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 CISCO-VISM-CONN-MIB?

CISCO-VISM-CONN-MIB is a Cisco Systems proprietary MIB reporting configuration and connection state for VISM (Voice Interworking Service Module) cards on Cisco MGX WAN switches, which require one active AAL5 bearer PVC and one active AAL5 control PVC between the VISM card and the PXM controller to carry VoIP traffic. Its channel table, keyed by channel number, reports row status, port number, local/remote loopback state, test type/state/round-trip-delay result, and PVC type. As a hardware/software-status MIB it lets an administrator confirm a VISM channel's bearer/control PVCs are up and loopback tests are passing when diagnosing a VoIP call-quality or connectivity issue. It is deployed on Cisco MGX WAN switches with VISM cards providing VoIP interworking. Engineers can download the CISCO-VISM-CONN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-VISM-CONN-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

Cisco MGX WAN switches with VISM (Voice Interworking Service Module) cards

Monitoring Examples

An administrator checks vismChanRTDResult after running a loopback test on a channel reporting call-quality complaints, to confirm round-trip delay across the VISM-to-PXM PVC path is within acceptable bounds.

What Can Be Monitored

VISM channel PVC type/status
loopback test state and round-trip delay

ciscoVismConnMIB	1.3.6.1.4.1.351.150.86			The MIB module to contains configuration and connection state information the VISM. For VoIP(Voice over IP) support, VISM needs one active AAL5 bearer PVC and one active AAL5 control PVC between the VISM card and the PXM. The redundant PVC feature is supported for AAL5 PVCs. Each redundant PVC pair has one active PVC and one standby PVC. There can be one AAL5 bearer redundant PVC pair and one AAL5 control redundant PVC pair. All PVCs are added on the ATM virtual port=1. For the AAL2 trunking application, there can be multiple AAL2 bearer PVCs. Also, AAL2 bearer PVC in this case, is between the two media gateways, instead of just between the VISM and the PXM. Up to 64 AAL2 bearer PVCs are supported for this application. Terminologies Used: PVC - Permanent Virtual Circuit OR Permanent Virtual Connection. SPVC - Soft Permanent Virtual Circuits. This is a PVC controlled by PNNI Controller. AAL - ATM Adaption Layer. PXM - Processor Switch Module. VC - Virtual Channel. CAC - Connection Admission Control. LCN - Logical Channel Number. VCI - Virtual Channel Identifier.

INT vismChanActivityState	1.3.6.1.4.1.351.110.5.5.3.1.1.1.28	INTEGER	read-only	Indicates whether the PVC is currently used to carry IP traffic or not, and whether it has failed. The possible states are: 'active (1)' : Channel is healthy and is currently designated to carry IP traffic. A channel can only be active if it is also unlocked. 'standby (2)' : Channel is healthy but not designated to carry IP traffic. Switchover to this channel is allowed. 'failed (3)' : Channel is unable to carry any traffic. 'unknown (4)' : Channel is unprotected and hence health of the channel is not monitored. The default value upon creation of the row will be 'standby (2)' for a protected channel and 'unknown (4)' for an unprotected channel. VISM may then transition a 'protected (1)' channel to active if it determines that this channel should be the one carrying the traffic.
U32 vismChanAisDelayTime	1.3.6.1.4.1.351.110.5.5.3.1.1.1.50	Unsigned32	read-write	This object defines the duration for which ATM network alarms on this PVC will be prevented from propagating onto the TDM side when AIS suppression is enabled.
T/F vismChanAisSuppression	1.3.6.1.4.1.351.110.5.5.3.1.1.1.49	TruthValue	read-write	AIS suppression can be enabled(true) or disabled(false). When AIS suppression is disabled on a PVC, ATM network alarms on that PVC will immediately propagate to the TDM side and cause T1/E1 line alarms. When AIS suppression is enabled on a PVC, ATM network alarms will not propagate to the TDM side and cause T1/E1 line alarms for the duration of the AIS delay time setting. However, if the ATM network alarms persist causing the AIS delay timer to expire, the ATM network alarms will be allowed to propagate onto the TDM side and cause T1/E1 line alarms.
INT vismChanApplication	1.3.6.1.4.1.351.110.5.5.3.1.1.1.38	INTEGER	read-write	This object defines the application that the LCN is used for. There are 4 types of PVCs known so far: 'control (1)' : Control PVC used for carrying control traffic only (XGCP packets). 'bearer (2)' : Bearer PVC, used for carrying voice payload traffic only. 'signaling(3)' : Signaling PVC, used for carrying the signaling protocol messages.
I32 vismChanCdvt	1.3.6.1.4.1.351.110.5.5.3.1.1.1.33	Integer32	read-write	This object defines the CDVT (Cell Delay Variation Tolerance) for the connection. CDVT is useful for determining the playout buffer size in the DSPs. This object is applicable only in AAL1 adaptation. For AAL2, the equivalent of this parameter, known as PDVT (Packet Delay Variation Tolerance) is internally derived.
I32 vismChanClrEgress	1.3.6.1.4.1.351.110.5.5.3.1.1.1.37	Integer32	read-write	This object defines the CLR (Cell Loss Ratio) for the PVC in egress direction. This field is also meaningful for VBR connections only.
I32 vismChanClrIngress	1.3.6.1.4.1.351.110.5.5.3.1.1.1.32	Integer32	read-write	This object defines the CLR (Cell Loss Ratio) for the PVC in ingress direction. This field is also meaningful for VBR connections only.
vismChanCnfGrpEntry	1.3.6.1.4.1.351.110.5.5.3.1.1.1		not-accessible	An entry for each voice channel. An entry is created when the vismChanRowStatus is set to 'add'. An entry is deleted when the vismChanRowStatus is set to 'del'.
vismChanCnfGrpTable	1.3.6.1.4.1.351.110.5.5.3.1.1		not-accessible	The channel configuration table for voice traffic.
INT vismChanConnType	1.3.6.1.4.1.351.110.5.5.3.1.1.1.9	INTEGER	read-write	This object identifies the connection type.
T/F vismChanDirectRoute	1.3.6.1.4.1.351.110.5.5.3.1.1.1.48	TruthValue	read-write	This object serves to associate a preferred route as directed route (corresponds to the preferred route object vismChanPrefRouteId). A directed route specifies that the associated preferred route is the only permission route for the connection to take. Should the associated preferred route be unavailable, the connection is failed. The object is not applicable if there is no associated preferred route with the connection or in other words if the object vismChanPrefRouteId has a value of 0.
I32 vismChanFallbackLcn	1.3.6.1.4.1.351.110.5.5.3.1.1.1.39	Integer32	read-write	This object defines the LCN to be used as a fallback mechanism, in case the primary PVC fails. This is applicable if the PVC is configured for redundancy. The redundancy is applicable for both applications i.e control PVC and bearer PVC. This object is applicable only if the vismChanProtection is set to 'protected'. It is mandatory if the PVC is protected.
INT vismChanLockingState	1.3.6.1.4.1.351.110.5.5.3.1.1.1.29	INTEGER	read-write	This object is used to control the switchover of protected channels. 'unlock (1)' : Transition state to unlock. A channel which is in lock state has to be brought to 'unlock (1)' state for it to be available for switchover. Whether a switchover to a channel is allowed or not is dependent on both vismChanActivityState and vismChanLockingState. A switchover is allowed if its vismChanActivityState is standby and its vismChanLockingState is unlock. Changing the vismChanLockingState to unlock does not cause a change in the vismChanActivityState. A channel which is in unlock state may carry traffic depending on its activity state (active or standby). 'lock (2)' : Transition state to 'lock (2)'. If the activity state is active, it transitions to standby and a switchover occurs to another channel which is standby and 'unlocked (1)'. When a channel is in 'lock (2)' state, switchover to this channel is not allowed. A channel which is in 'lock (2)' state, is always in either standby or failed state. Hence it will not carry any traffic. Switchover to a channel which is in 'lock (2)' state is not allowed. This object can be set to 'locked (2)' to force a switchover and/or to perform maintenance operations related to that channel. A channel that is 'unprotected' will always be in 'unlock (1)' state. It can not be set to 'lock (2)' state.
INT vismChanLocRmtLpbkState	1.3.6.1.4.1.351.110.5.5.3.1.1.1.4	INTEGER	read-write	Loopback on cellbus in egress direction. 'enable (1)' : When you enable this option on a connection (channel) then all the cells that are coming from the network side would be looped back toward the network and all the frames coming from the user side would be dropped. 'disable (2)': disables the remote loopback for a channel.
I32 vismChanMbsEgress	1.3.6.1.4.1.351.110.5.5.3.1.1.1.36	Integer32	read-write	This object defines the MBS (Max. Burst Size) for a PVC in egress direction. This object is meaningful for VBR connections only.
I32 vismChanMbsIngress	1.3.6.1.4.1.351.110.5.5.3.1.1.1.31	Integer32	read-write	This object defines the MBS (Max. Burst Size). This object is meaningful for VBR connections only. This object defines the MBS value for the ingress direction of the PVC. The MBS value cannot be greater than 10 times vismChanScrIngress value.
I32 vismChanNumNextAvailable	1.3.6.1.4.1.351.110.5.5.3.1.2	Integer32	read-only	This object contains the next unused channel number. When channels are available the range is 32..510. This number can be used in channel config table. Value 0 for this object indicates that no more channels are available.
I32 vismChanPortNum	1.3.6.1.4.1.351.110.5.5.3.1.1.1.3	Integer32	read-write	This refers to the virtual port between VISM and PXM. This number is defaulted to the appropriate number for the shelf, in PXM1 the value is 1 and 255 for PXM1E.
INT vismChanPreference	1.3.6.1.4.1.351.110.5.5.3.1.1.1.27	INTEGER	read-write	This object is used to identify a PVC as primary or secondary. The primary PVC should be added before the secondary. Similarly secondary should be deleted before deleting the primary. When the protection group is setup, the primary becomes active and secondary becomes standby. The distinction of 'primary (1)' and 'secondary(2)' is meaningful only if the PVC is 'protected (1)'.
U32 vismChanPrefRouteId	1.3.6.1.4.1.351.110.5.5.3.1.1.1.47	Unsigned32	read-write	This object serves to associate a preferred route with a connection. The value of '0' means no preferred route is associated with this connection. Usage: - If the value of this set to 0, the object vismChanDirectRoute is automatically set to FALSE by the agent. - The preferred route is defined in cwaPrefRouteConfTable object.
INT vismChanProtection	1.3.6.1.4.1.351.110.5.5.3.1.1.1.26	INTEGER	read-write	This object is used to configure a PVC protection group (or redundant group) with the PVCs protecting each other. Currently only two PVCs are supported in a protection group. One of them is primary and the other one is secondary. This is intended for PVCs designated to carry control traffic and needs to be protected. However the same PVC may also be used to carry VoIP bearer traffic or other traffic. Channels that are 'protected (1)' share the following characteristics: 1. They are monitored for their health (including emission of traps in case of state changes). 2. An active channel is protected by another protected channel which is standby. This means when an active channel fails, switchover to another channel will happen if one is available. 3. It is also possible to do a forced switchover (through locking). Even in the case of forced switchover, switchover to another channel, which is in standby, will happen. 4. Channels may be locked to force switchover and/or to take the channel out of service in a graceful fashion. This object takes the default value of 'unprotected (2)' during the creation of the table entry. Once the primary and secondary channels have been created as 'unprotected (2)' channels, they can be 'protected (1)' by doing a SET on the primary channel by specifying the vismChanProtection as protected and by specifying the vismChanFallbackLcn as the LCN number of the secondary channel. The sequence of operations for setting up the 'protection (1)' group is: step 1: Add primary channel as unprotected step 2: Add secondary channel as unprotected. The PCR value for the secondary should be the same as that of the primary. step 3: Do a SET on the primary channel with vismChanProtection set to 'protected (1)' and vismChanFallbackLcn set to the LCN number of the secondary channel. This operation sets-up the protection group. The primary channel becomes active and the secondary channel becomes standby. Please note that all the CAC related parameters for the both the PVCs in the protecting group should be same. In other words the vismChanCacMaster, vismChanCarrierLossPolicy, vismChanCacRejectionPolicy, VAD tolerance etc.. should have the same value for the PVCs that are protecting each other, else the set request to protect two channels will be rejected. Once the protection group is setup, if the active channel fails, it automatically switches over to the standby. The standby channel then becomes active. The channels can be removed from the protection group by setting this object to unprotected. Deletion of a 'protected (1)' channel is not allowed. Channels have to be removed from the protection group first before deleting. The sequence of operations for deleting 'protected (1)' channels are: step 1: Remove the channels from the protection group by setting vismChanProtection to unprotected. step 2: Delete secondary channel. step 3: Delete primary channel.

T/F vismChanReroute	1.3.6.1.4.1.351.110.5.5.3.1.1.1.40	TruthValue	read-write	This is used by the administrator to trigger the re-routing of the connection. The re-routing takes effect, when this object is set to 'true (1)'. When set to 'false (2)', no action is taken. A get on this object always returns 'false (2)'.
INT vismChanRowStatus	1.3.6.1.4.1.351.110.5.5.3.1.1.1.2	INTEGER	read-write	An entry is created by setting this object to 'add (1)' : Adds an entry to the table. 'mod (3)' : This is used to modify an existing entry. 'del (2)' : This is used to delete an existing. 'outOfService (4)': Setting this object to this value takes the channel out of service or brings the channel 'down (2)'. The channel can be brought 'up (1)' again by setting the object to 'mod (3)'. If there is redundant configuration for the channel, an active channel can be deleted only after locking the channel.

INT vismFarEndAddressType	1.3.6.1.4.1.351.110.5.5.3.1.1.1.41	INTEGER	read-write	The address type can be one of five types: NSAP, E164, GWID, notapplicable or unspecified. It determines which object contains the scope for the VCCI, i.e. whether the VCCI needs to be unique relative to NSAP, E164 address or GWID. 'notApplicable (1)' : no valid addresses are required and no validation of VCCI uniqueness for a remote address is performed. 'nsap (2)' : object vismFarEndNSAPAddress contains the address. 'e164 (3)' : object vismFarEndE164Address contains the address. 'gwid (4)' : object vismFarEndGWIDAddress contains the address. 'unspecified (5)' : no valid addresses are required but VCCI needs to be unique. While this object is writeable, it is recommended not to change the value of this object once it has been created. However, upon modification to any value other than notapplicable, it will be ensured that the resulting combination of VCCI and remote address is unique. Requests that would result in a non-unique combination will be rejected. If the vismFarEndAddressType is one of 'nsap', 'e164' or 'gwid', the far end address has to be specified.
STR vismFarEndE164Address	1.3.6.1.4.1.351.110.5.5.3.1.1.1.42	DisplayString	read-write	The E.164 address of the far end peer. The address is expressed as decimal numbers with up to 15 digits. If the vismFarEndAddressType is different from e164, this object is not applicable and it should be ignored. This object serves as the scope for VCCI identifiers (vismVCCI), if vismFarEndAddressType is equal to e164. In that case, the combination of (vismFarEndE164Address, vismVCCI) will always be unique for any given agent. It thus constitutes a label denoting the scope for a VCCI address space; it has no purpose otherwise. While this object is writeable, it is recommended not to change the value of this object once it has been created. However, upon modification, it will be ensured that the resulting combination of VCCI and remote E164 address is unique (as long as the remote address type is E164). Requests that would result in a non-unique combination will be rejected. Beyond this, there are no other integrity constraints that will be enforced for this object. This includes network-level consistency with the actual address of the remote peer. The value of this object cannot be modified when there are active calls on this PVC. The valid characters allowed are '0..9'.
STR vismFarEndGWIDAddress	1.3.6.1.4.1.351.110.5.5.3.1.1.1.43	DisplayString	read-write	The gateway ID of the far end peer. The address is expressed as ASCII characters. If the vismFarEndAddressType is different from gwid(4), this object is not applicable and it should be ignored. This object serves as the scope for VCCI identifiers (vismVCCI) if vismFarEndAddressType is equal to gwid(4). In that case, the combination of (vismFarEndGWIDAddress, vismVCCI) will always be unique for any given agent. It thus constitutes a label denoting the scope for a VCCI address space; it has no purpose otherwise. While this object is writeable, it is recommended not to change the value of this object once it has been created. However, upon modification, it will be ensured that the resulting combination of VCCI and far end GWID address is unique (as long as the vismFarEndAddress type is GWID). Requests that would result in a non-unique combination will be rejected. Beyond this, there are no other integrity constraints that will be enforced for this object. This includes network-level consistency with the actual address of the remote peer. The value of this object cannot be modified when there are active calls on this PVC. All ASCII characters are allowed by this object.
OCT vismFarEndNSAPAddress	1.3.6.1.4.1.351.110.5.5.3.1.1.1.44	OCTET STRING	read-write	This object contains the 20 byte NSAP address of the far end peer. If the vismFarEndAddressType is different from 'nsap', this object is not applicable and it should be ignored. This object serves as the scope for VCCI identifiers (vismVCCI) if vismFarEndAddressType is equal to 'nsap'. In that case, the combination of (vismFarEndNSAPAddress, vismVCCI) will always be unique for any given agent. It thus constitutes a label denoting the scope for a VCCI address space; it has no purpose otherwise. While this object is writeable, it is recommended not to change the value of this object once it has been created. However, upon modification, it will be ensured that the resulting combination of VCCI and far end NSAP address is unique (as long as the far end address type is GWID). Requests that would result in a non-unique combination will be rejected. Beyond this, there are no other integrity constraints that will be enforced for this object. This includes network-level consistency with the actual address of the remote peer. The value of this object cannot be modified when there are active calls on this PVC. When the user adds a connection, by default the value of this object will be set to vismRemoteNSAP, unless the user specifies a value for this object. This object is represented as hex (0 .. 9,A .. F).

I32 vismStateChanNum	1.3.6.1.4.1.351.110.5.5.3.2.1.1.1	Integer32	read-only	Refers to the channel Number LCN.
I32 vismVCCI	1.3.6.1.4.1.351.110.5.5.3.1.1.1.45	Integer32	read-write	The VCCI, or Virtual Circuit Connection Identifier, is a variable that identifies a virtual circuit connection between two nodes. A virtual circuit connection, or VCC, consists of one virtual circuit link or a series of concatenated virtual circuit links. In its most common usage, the value of the VCCI is unique between the nodes at the extremities of the virtual circuit connection, but not on a network-wide basis. Hence, its value needs to be qualified by the ATM addresses of these end nodes. At one of these end nodes, its value needs to be qualified by the ATM address of the far-end node. Some applications can extend this definition to make the VCCI value unique on a network-wide basis. This is specially possible when VCCIs are administered from a management system and not locally assigned by a node. In this MIB, the VCCI serves as a label to be assigned by an external application. VCCIs need to be unique for a given remote peer, however, the same VCCI can be reused for different remote peers. Accordingly, the combination of (remote address, VCCI) will always be unique for any given agent. This allows a controller to refer to a VC by the VCCI and remote peer address, in contrast to VPI/VCI and port. It thus constitutes a convenience feature, providing an alternative identification scheme for a VC which is managed by an outside user, such as a management system. The remote peer address can be specified in NSAP, E.164, or GWID format, as indicated by the address type (vismRemoteAddressType). Depending on the address type specified, uniqueness will be relative to NSAP, E.164 address, or GWID. It is recommended not to change the value of this object once it has been created. However, upon modification, it will be ensured that the resulting combination of VCCI and remote address is unique. Requests that would result in a non-unique combination will be rejected. Beyond this, there are no other integrity constraints that will be enforced for this object. This includes network-level consistency whether the remote peer, or an external controller, use the same VCCI designation for the VC.
INT vismVpcFlag	1.3.6.1.4.1.351.110.5.5.3.1.1.1.17	INTEGER	read-write	This object specifies the connection type which is used by PXM to setup connection.
