Description: Manages Cisco Video Distribution Switch fabric configuration and video stream routing.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is VDS-MIB?
VDS-MIB defines Virtual Data Source (VDS) extensions to the standard Remote Monitoring (RMON) MIB, letting a device present filtered "virtual" monitoring data sources rather than functioning as a video-distribution product as its short name might suggest. It exposes configuration objects for defining virtual data sources by selecting an underlying physical/logical interface and optionally narrowing the source further by VLAN or address filters. Its monitoring role is primarily to configure which traffic subset a given RMON probe/agent instance analyzes rather than exposing hardware/environmental status directly -- vdsControlIfName/vdsControlIfDescr/vdsControlIfAlias identify the physical interface backing a virtual source, and vdsControlVlanSelIndex/vdsControlAddrSelIndex configure VLAN- or address-based selection criteria (with the associated "Negate" objects inverting the filter). It explicitly extends the IETF RMON MIB (RFC 2819) framework, tying vdsControlParent back to a parent RMON data source. It is typically deployed on switches or RMON-capable network probes where operators want to scope RMON statistics collection to a specific VLAN or address range rather than an entire physical port. Engineers implementing or auditing this functionality typically reference the VDS-MIB RFC/standard documentation for the authoritative specification.
IPNetwork Monitor allows you to monitor SNMP objects defined in VDS-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- extension to the vendor-neutral IETF RMON standard, implemented on switches or RMON-capable network probes rather than tied to one manufacturer
Monitoring Examples
An administrator would create an entry in vdsControlTable/vdsControlEntry indexed by vdsControlIndex, set vdsControlParent to reference the underlying interface, and populate vdsControlVlanSelIndex/vdsControlAddrSelIndex (with vdsControlVlanSelNegate/vdsControlAddrSelNegate as needed) to scope RMON monitoring to a single VLAN or address range. Checking vdsControlIfDescr/vdsControlIfName/vdsControlIfAlias for that entry lets the operator confirm which physical interface a given virtual data source is actually built on, useful when troubleshooting why RMON statistics for a VLAN look inconsistent with expectations.
What Can Be Monitored
- virtual data source to physical interface mapping
- VLAN selection filter for a virtual source
- address selection filter for a virtual source
- filter negation (include vs exclude) settings
- parent data source association

| vdsMIB | 1.3.6.1.4.1.99999.64 | The MIB module for representing Virtual Data Source Extensions to the Remote Monitoring MIB. | ||
| vdsMIBObjects | 1.3.6.1.4.1.99999.64.1 | |||
| vdsControl | 1.3.6.1.4.1.99999.64.1.1 | |||
| BIT vdsSelectCaps | 1.3.6.1.4.1.99999.64.1.1.1 | Bits | read-only | An indication of the virtual data source packet selection capabilities of this agent. This object should be set during system initialization, and should remain stable until the next re-initialization of the agent. If this agent supports virtual LAN based packet selection, and therefore allows entries to be created in the vdsVlanSelTable, then the 'vlanSelect' BIT will be set. If this agent allows multiple vdsVlanSelEntries to be configured for a single virtual data source, then the 'vlanMulti' BIT will be set. If this agent supports network address based packet selection, and therefore allows entries to be created in the vdsAddrSelTable, then the 'addrSelect' BIT will be set. If this agent allows multiple vdsAddrSelEntries to be configured for a single virtual data source, then the 'addrMulti' BIT will be set. If this agent supports protocol based packet selection, and therefore allows entries to be created in the vdsProtoSelTable, then the 'protoSelect' BIT will be set. If this agent allows multiple vdsProtoSelEntries to be configured for a single virtual data source, then the 'protoMulti' BIT will be set. If this agent supports QoS based packet selection, and therefore allows entries to be created in the vdsQosSelTable, then the 'qosSelect' BIT will be set. If this agent allows multiple vdsQosSelEntries to be configured for a single virtual data source, then the 'qosMulti' BIT will be set. If this agent supports channelTable based packet selection, and therefore allows entries to be created in the vdsChanSelTable, then the 'chanSelect' BIT will be set. If this agent allows multiple vdsChanSelEntries to be configured for a single virtual data source, then the 'chanMulti' BIT will be set. If this agent supports URL based HTTP packet selection, and therefore allows entries to be created in the vdsUrlSelTable, then the 'urlSelect' BIT will be set. If this agent allows multiple vdsUrlSelEntries to be configured for a single virtual data source, then the 'urlMulti' BIT will be set. If this agent supports combinations of packet selection mechanisms to be used within the same virtual data source, and therefore allows entries to be created in at least two of the vds*SelTables, then the 'comboSelect' BIT will be set. |
| vdsControlTable | 1.3.6.1.4.1.99999.64.1.1.2 | not-accessible | This table contains one row per virtual data source, as configured by NMS application(s). It is used to control the overall configuration of each virtual data source. The agent will maintain a proprietary virtual interface, on behalf of each active vdsControlEntry. All packets which are monitored on the 'parent' interface (identified by the vdsControlParent object) will be classified and processed according to the configuration for each relevant vdsControlEntry and associated vds*SelEntries. Each of the selection algorithms produces a boolean result (i.e., 'selected' or 'not selected'), and these results are combined (i.e., logical AND/OR expression) to produce a single boolean result for the packet. If a packet is selected, then it will be somehow presented for monitoring on the associated virtual interface maintained by the agent. Since a virtual interface only exists in the RMON agent, it is expected that the same agent will be supporting an implementation of one or more RMON MIBs, which will allow RMON control table dataSource objects to reference the ifEntry created on behalf of a vdsControlEntry. The implementation details of this 'linkage', or any use of this ifEntry other than remote monitoring, is outside the scope of this document. Additional entries in the vdsVlanSelTable, vdsAddrSelTable, vdsProtoSelTable, vdsQosSelTable, vdsChanSelTable, and/or vdsUrlSelTable will be required, depending on the configuration of this entry. At least one selection mechanism must be configured per vdsControlEntry. The initial state of all packet selection algorithms is 'not selected', therefore a virtual data source will have no effect unless a vds*SelEntry is properly configured (in addition to this entry). NMS applications must configure the appropriate vds*SelEntries before activated this control entry, and those vds*SelEntries may not be modified while this entry is active. It is an implementation-specific manner as to the complexity and capacity of the entries allowed in this table. Actual configurations will be constrained by agent functionality and platform resources. | |
| vdsControlEntry | 1.3.6.1.4.1.99999.64.1.1.2.1 | not-accessible | Information about a particular virtual data source. | |
| I32 vdsControlIndex | 1.3.6.1.4.1.99999.64.1.1.2.1.1 | Integer32 | not-accessible | An arbitrary and unique index for this vdsControlEntry. |
| SMO vdsControlParent | 1.3.6.1.4.1.99999.64.1.1.2.1.2 | SmonDataSource | read-create | This object identifies the actual data source to be used as the source of all packets for this virtual data source. A valid dataSourceCapsEntry must be maintained by the agent on behalf of this 'parent' interface. If the ifOperStatus for the parent's ifEntry is not equal to 'up', then no packets will be available to this virtual data source. This object must identify a valid SmonDataSource. Virtual data sources cannot be represented in the SMON dataSourceCapsTable. However, the dataSourceRmonCaps object in the dataSourceCapsEntry for this entry can be used to identify most of the attributes that a virtual data source inherits from its parent. The 'countErrFrames', 'countAllGoodFrames', and 'babyGiantsCountAsGood' BITs are all inherited from the parent data source. The 'countAnyRmonTables' BIT is not inherited, as it is assumed to be set for virtual data sources. An agent is required to support at least one RMON collection type for each virtual data source. This object may not be modified if the associated vdsControlStatus object is equal to active(1). |
| STR vdsControlIfDescr | 1.3.6.1.4.1.99999.64.1.1.2.1.3 | DisplayString | read-create | A textual string describing this virtual data source. This configured value is used for the value of the ifDescr instance created on behalf of this control entry. |
| STR vdsControlIfName | 1.3.6.1.4.1.99999.64.1.1.2.1.4 | DisplayString | read-create | A textual string naming this virtual data source. This configured value is used for the value of the ifName instance created on behalf of this control entry. |
| STR vdsControlIfAlias | 1.3.6.1.4.1.99999.64.1.1.2.1.5 | DisplayString | read-create | A textual string specifying an alias name for this virtual data source. This configured value is used for the value of the ifAlias instance created on behalf of this control entry. |
| I32 vdsControlVlanSelIndex | 1.3.6.1.4.1.99999.64.1.1.2.1.6 | Integer32 | read-create | This object controls whether any Virtual LAN traffic selection is performed on behalf of this vdsControlEntry, and is used in conjunction with the vdsControlVlanSelNegate object. If this object contains the value zero, then no Virtual LAN based traffic selection is performed on behalf of this vdsControlEntry. Otherwise, this object identifies one or more rows in the vdsVlanSelTable, (i.e., with the same vdsVlanSelIndex value as identified by this object) which specify the Virtual LANs to select for monitoring, from the parent data source. This object may not be modified if the associated vdsControlStatus object is equal to active(1). |
| T/F vdsControlVlanSelNegate | 1.3.6.1.4.1.99999.64.1.1.2.1.7 | TruthValue | read-create | This object controls the boolean sense of the result of the Virtual LAN based packet selection algorithm, and has no effect if the associated vdsControlVlanSelIndex object is equal to zero. If a packet that is 'tested' against the selection list (specified by the vdsControlVlanSelIndex) would be selected, and this object equals 'true', then the packet is not selected. This object may not be modified if the associated vdsControlStatus object is equal to active(1). |
| I32 vdsControlAddrSelIndex | 1.3.6.1.4.1.99999.64.1.1.2.1.8 | Integer32 | read-create | This object controls whether any network address based traffic selection is performed on behalf of this vdsControlEntry, and is used in conjunction with the vdsControlAddrSelNegate object. If this object contains the value zero, then no network address based traffic selection is performed on behalf of this vdsControlEntry. Otherwise, this object identifies one or more rows in the vdsAddrSelTable, (i.e., with the same vdsAddrSelIndex value as identified by this object) which specify the hosts and/or host-pairs to select for monitoring, from the parent data source. This object may not be modified if the associated vdsControlStatus object is equal to active(1). |
| T/F vdsControlAddrSelNegate | 1.3.6.1.4.1.99999.64.1.1.2.1.9 | TruthValue | read-create | This object controls the boolean sense of the result of the network address based packet selection algorithm, and has no effect if the associated vdsControlAddrSelIndex object is equal to zero. If a packet that is 'tested' against the selection list (specified by the vdsControlAddrSelIndex) would be selected, and this object equals 'true', then the packet is not selected. This object may not be modified if the associated vdsControlStatus object is equal to active(1). |
| I32 vdsControlProtoSelIndex | 1.3.6.1.4.1.99999.64.1.1.2.1.10 | Integer32 | read-create | This object controls whether any protocol based traffic selection is performed on behalf of this vdsControlEntry, and is used in conjunction with the vdsControlProtoSelNegate object. If this object contains the value zero, then no protocol based traffic selection is performed on behalf of this vdsControlEntry. Otherwise, this object identifies one or more rows in the vdsProtoSelTable, (i.e., with the same vdsProtoSelIndex value as identified by this object) which specify the protocol encapsulations to select for monitoring, from the parent data source. This object may not be modified if the associated vdsControlStatus object is equal to active(1). |
| T/F vdsControlProtoSelNegate | 1.3.6.1.4.1.99999.64.1.1.2.1.11 | TruthValue | read-create | This object controls the boolean sense of the result of the protocol based packet selection algorithm, and has no effect if the associated vdsControlProtoSelIndex object is equal to zero. If a packet that is 'tested' against the selection list (specified by the vdsControlProtoSelIndex) would be selected, and this object equals 'true', then the packet is not selected. This object may not be modified if the associated vdsControlStatus object is equal to active(1). |
| I32 vdsControlQosSelIndex | 1.3.6.1.4.1.99999.64.1.1.2.1.12 | Integer32 | read-create | This object controls whether any quality of service based traffic selection is performed on behalf of this vdsControlEntry, and is used in conjunction with the vdsControlQosSelNegate object. If this object contains the value zero, then no quality of service based traffic selection is performed on behalf of this vdsControlEntry. Otherwise, this object identifies one or more rows in the vdsQosSelTable, (i.e., with the same vdsQosSelIndex value as identified by this object) which specify the QoS classifications to select for monitoring, from the parent data source. This object may not be modified if the associated vdsControlStatus object is equal to active(1). |
| T/F vdsControlQosSelNegate | 1.3.6.1.4.1.99999.64.1.1.2.1.13 | TruthValue | read-create | This object controls the boolean sense of the result of the quality of service based packet selection algorithm, and has no effect if the associated vdsControlQosSelIndex object is equal to zero. If a packet that is 'tested' against the selection list (specified by the vdsControlQosSelIndex) would be selected, and this object equals 'true', then the packet is not selected. This object may not be modified if the associated vdsControlStatus object is equal to active(1). |
| I32 vdsControlChanSelIndex | 1.3.6.1.4.1.99999.64.1.1.2.1.14 | Integer32 | read-create | This object controls whether any content (channelTable) based traffic selection is performed on behalf of this vdsControlEntry. If this object contains the value zero, then no content based traffic selection is performed on behalf of this vdsControlEntry. Otherwise, this object identifies one or more rows in the vdsChanSelTable, (i.e., with the same vdsChanSelIndex value as identified by this object) which specify the RMON channels to select for monitoring, from the parent data source. This object may not be modified if the associated vdsControlStatus object is equal to active(1). |
| I32 vdsControlUrlSelIndex | 1.3.6.1.4.1.99999.64.1.1.2.1.15 | Integer32 | read-create | This object controls whether any URL based traffic selection is performed on behalf of this vdsControlEntry, and is used in conjunction with the vdsControlUrlSelNegate object. If this object contains the value zero, then no URL based traffic selection is performed on behalf of this vdsControlEntry. Otherwise, this object identifies one or more rows in the vdsUrlSelTable, (i.e., with the same vdsUrlSelIndex value as identified by this object) which specify the URL classifications to select for monitoring, from the parent data source. This object may not be modified if the associated vdsControlStatus object is equal to active(1). |
| T/F vdsControlUrlSelNegate | 1.3.6.1.4.1.99999.64.1.1.2.1.16 | TruthValue | read-create | This object controls the boolean sense of the result of the URL based packet selection algorithm, and has no effect if the associated vdsControlUrlSelIndex object is equal to zero. If a packet that is 'tested' against the selection list (specified by the vdsControlUrlSelIndex) would be selected, and this object equals 'true', then the packet is not selected. This object may not be modified if the associated vdsControlStatus object is equal to active(1). |
| INT vdsControlExprType | 1.3.6.1.4.1.99999.64.1.1.2.1.17 | INTEGER | read-create | This object controls how the various packet selection mechanisms are combined, on behalf of this vdsControlEntry. Each vds*SelTable group configured on behalf of this entry will be evaluated according to the rules specified in each table. If combinations of packet selection sources are supported, then this object can be used to control how the boolean results from each selection process are combined. If this object contains the value 'union(1)', then the packets contained in this virtual data source are selected by the union of all packet selection mechanisms specified in this entry. I.e., any configured selection mechanism that produces a 'selected' result will cause a packet to be selected for the virtual data source. If this object contains the value 'intersect(1)', then the packets contained in this virtual data source are selected by the intersection of all packet selection mechanisms specified in this entry. I.e., all configured selection mechanisms must produce a 'selected' result, for a packet to be selected for the virtual data source. This object may not be modified if the associated vdsControlStatus object is equal to active(1). |
| NUM vdsControlIfIndex | 1.3.6.1.4.1.99999.64.1.1.2.1.18 | InterfaceIndexOrZero | read-only | This object identifies the virtual interface that has been created on behalf of this vdsControlEntry. Unless this entry is activated, this object will contain the value zero. Upon row activation, the agent will set this object to the ifIndex value assigned on behalf of this vdsControlEntry. The associated ifEntry (with an ifType of 'propVirtual') will exist in the ifTable as long as this entry is active. |
| STR vdsControlOwner | 1.3.6.1.4.1.99999.64.1.1.2.1.19 | OwnerString | read-create | The entity that configured this entry and is therefore using the resources assigned to it. |
| STO vdsControlStorageType | 1.3.6.1.4.1.99999.64.1.1.2.1.20 | StorageType | read-create | The non-volatile storage behavior for this entry. |
| ROW vdsControlStatus | 1.3.6.1.4.1.99999.64.1.1.2.1.21 | RowStatus | read-create | The status of this virtual data source entry. An entry may not exist in the active state unless all objects in the entry have an appropriate value. If this object is not equal to active(1), any RMON collection data in progress, for which the dataSource object references the ifEntry associated with this virtual data source, and the ifEntry itself, shall be deleted. |
| vdsSelect | 1.3.6.1.4.1.99999.64.1.2 | |||
| vdsVlanSelTable | 1.3.6.1.4.1.99999.64.1.2.1 | not-accessible | This table controls how Virtual LAN based packet selection is performed on behalf of particular vdsControlEntries configured on this agent. For each vdsControlEntry that references this table, the vdsControlParent object must specify a data source in the form 'ifIndex.', where 'I' represents an ifIndex value of an interface which supports IEEE 802.1Q VLAN encapsulation. VLAN data sources are identified by the IEEE VLAN ID field [DOT1Q]. All packets which belong to the VLAN identified by the vdsVlanSelVID object shall be selected. All entries with the same vdsControlVlanSelIndex are evaluated as a group, and an individual packet is selected if the evaluation of any row within the group produces a 'selected' result. There is no evaluation ordering defined for each row within a group, and an agent may choose to stop evaluation after the first 'selected' result. It is an implementation-specific manner as to the complexity and capacity of the entries allowed in this table. Actual configurations will be constrained by agent functionality and platform resources. | |
| vdsVlanSelEntry | 1.3.6.1.4.1.99999.64.1.2.1.1 | not-accessible | Information about a particular Virtual LAN based packet selection control entry. | |
| I32 vdsVlanSelIndex | 1.3.6.1.4.1.99999.64.1.2.1.1.1 | Integer32 | not-accessible | An arbitrary and unique group index for this vdsVlanSelEntry. All entries in this table, for which this object contains the same value, will be evaluated together as a group, on behalf of particular vdsControlEntries. |
| I32 vdsVlanSelSubIndex | 1.3.6.1.4.1.99999.64.1.2.1.1.2 | Integer32 | not-accessible | An arbitrary and unique index for this vdsVlanSelEntry. Note that no packet selection algorithm evaluation order is implied by the value of this object. |
| I32 vdsVlanSelVID | 1.3.6.1.4.1.99999.64.1.2.1.1.3 | Integer32 | read-create | The VLAN ID value to be used for packet selection. Packets determined to belong to the VLAN identified by this object will be included for selection. The packets selected are based on the IEEE 802.1Q VLAN-ID (VID), for each good frame attributed to the data source for the collection. Tagged packets match the VID for the range between 1 and 4094. An external RMON probe MAY detect VID=0 on an Inter Switch Link, in which case the packet belongs to a VLAN determined by the PVID of the ingress port. This object may not be modified if the associated vdsVlanSelStatus object is equal to active(1). |
| STO vdsVlanSelStorageType | 1.3.6.1.4.1.99999.64.1.2.1.1.4 | StorageType | read-create | The non-volatile storage behavior for this entry. |
| ROW vdsVlanSelStatus | 1.3.6.1.4.1.99999.64.1.2.1.1.5 | RowStatus | read-create | The status of this Virtual LAN selection entry. An entry may not exist in the active state unless all objects in the entry have an appropriate value. This object may not be modified while any vdsControlEntry that references this entry is active. |
| vdsAddrSelTable | 1.3.6.1.4.1.99999.64.1.2.2 | not-accessible | This table controls how network address based packet selection is performed on behalf of particular vdsControlEntries configured on this agent. Packet selection can be based on a single host address, or a host-address pair, and is determined only by the Source and Destination addresses found in each packet, not by the 'packet direction' on the network. One address or address- pair is specified in each vdsAddrSelEntry. All entries with the same vdsControlAddrSelIndex are evaluated as a group, and an individual packet is selected if the evaluation of any row within the group produces a 'selected' result. There is no evaluation ordering defined for each row within a group, and an agent may choose to stop evaluation after the first 'selected' result. It is an implementation-specific manner as to the complexity and capacity of the entries allowed in this table. Actual configurations will be constrained by agent functionality and platform resources. | |
| vdsAddrSelEntry | 1.3.6.1.4.1.99999.64.1.2.2.1 | not-accessible | Information about a particular address based packet selection control entry. | |
| I32 vdsAddrSelIndex | 1.3.6.1.4.1.99999.64.1.2.2.1.1 | Integer32 | not-accessible | An arbitrary and unique group index for this vdsAddrSelEntry. All entries in this table, for which this object contains the same value, will be evaluated together as a group, on behalf of particular vdsControlEntries. |
| I32 vdsAddrSelSubIndex | 1.3.6.1.4.1.99999.64.1.2.2.1.2 | Integer32 | not-accessible | An arbitrary and unique index for this vdsAddrSelEntry. Note that no packet selection algorithm evaluation order is implied by the value of this object. |
| INT vdsAddrSelType | 1.3.6.1.4.1.99999.64.1.2.2.1.3 | INTEGER | read-create | This object controls the way vdsAddrSelEntries are evaluated, for packet selection purposes. If this object has a value of 'host(1)', then this entry selects all packets addressed to or from 'host1', and only the vdsAddrSelHost1 and vdsAddrSelHost1Mask objects are used in this packet selection process. Refer to the description clauses for these objects for details on the packet selection algorithm. If this object has a value of 'conversation(2)', then this entry selects all packets addressed from 'host1' to 'host2', and all packets addressed from 'host2' to 'host1'. The vdsAddrSelHost1, vdsAddrSelHost1Mask, vdsAddrSelHost2 and vdsAddrSelHost2Mask objects are used in the packet selection process. Refer to the description clauses for these objects for details on the packet selection algorithm. This object may not be modified if the associated vdsAddrSelStatus object is equal to active(1). |
| OCT vdsAddrSelNetProtoID | 1.3.6.1.4.1.99999.64.1.2.2.1.4 | OCTET STRING | read-create | This object is used in conjunction with the vdsAddrSelNetProtoParms object to specify the protocolDirEntry which identifies the network layer protocol used in this entry. Only packets which contain a network layer protocol which matches the protocol identified by this entry will be considered in the address based packet selection algorithms defined in this table. If an 'exact' encapsulation of a network protocol is specified, (e.g., a specific base layer encapsulation is present instead of a 'wild-card' base layer, or a tunneled network encapsulation is present) then only packets which match the same encapsulation (i.e., same protocols up to and including the last protocol layer specified in this entry) will be considered in the address based packet selection algorithms defined in this table. The associated vdsAddrSelHost1, vdsAddrSelHostMask, vdsAddrSelHost2, and vdsAddrSelHost2Mask objects will be interpreted according to the value of this object and the associated vdsAddrSelNetProtoParms object. This object may not be modified if the associated vdsAddrSelStatus object is equal to active(1). |
| OCT vdsAddrSelNetProtoParms | 1.3.6.1.4.1.99999.64.1.2.2.1.5 | OCTET STRING | read-create | This object is used in conjunction with the vdsAddrSelNetProtoID object to specify the protocolDirEntry which identifies the network layer protocol used in this entry. The associated vdsAddrSelHost1, vdsAddrSelHostMask, vdsAddrSelHost2, and vdsAddrSelHost2Mask objects will be interpreted according to the value of this object and the associated vdsAddrSelNetProtoID object. Refer to the vdsAddrSelNetProtoID description clause for more details pertaining to this object. This object may not be modified if the associated vdsAddrSelStatus object is equal to active(1). |
| OCT vdsAddrSelHost1Addr | 1.3.6.1.4.1.99999.64.1.2.2.1.7 | OCTET STRING | read-create | This object identifies a network address to be used as a parameter in the address based packet selection process. It must be a well-formed address according to the encoding rules defined for the network protocol for this entry (identified by the vdsAddrSelNetProtoID and vdsAddrSelNetProtoParms objects). For each examined packet which matches the network type (according to the algorithm defined in the vdsAddrSelNetProtoID object): 1) 'Bitwise AND' each octet of this object with each octet of the associated vdsAddrSelHost1Mask value. Note that the result of this step is a constant value, and may be used for all relevant packets, rather than re-computing this value each time a packet is processed. 2) 'Bitwise AND' each octet of the network source address in the packet with each octet of the associated vdsAddrSelHost1Mask value 3) Compare the results of step (1) and step (2); if equal, the packet is selected; otherwise continue to step (4) 4) 'Bitwise AND' each octet of the network destination address in the packet with each octet of the associated vdsAddrSelHost1Mask value 5) Compare the results of step (1) and step (4); if equal, the packet is selected, otherwise it is not selected. This object may not be modified if the associated vdsAddrSelStatus object is equal to active(1). |
| OCT vdsAddrSelHost1Mask | 1.3.6.1.4.1.99999.64.1.2.2.1.8 | OCTET STRING | read-create | This object identifies a mask that may be applied during network address packet selection. It is used differently, depending on the value of the associated vdsAddrSelType object. It must be a well-formed address mask, according to the encoding rules defined for the network protocol for this entry (identified by the vdsAddrSelNetProtoID and vdsAddrSelNetProtoParms objects). If this object is smaller in length than the vdsAddrSelHost1Addr object, then this object shall be conceptually extended with 'one' bits.
