Description: Extreme Networks MIB for Policy-Based Quality of Service (PBQoS), managing QoS policies and traffic classification rules on Extreme switches.

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 EXTREME-PBQOS-MIB?

EXTREME-PBQOS-MIB is a vendor-specific Extreme Networks MIB (extremeQosPolicy, under the extremeAgent enterprise tree) that models Policy-Based QoS rules for classifying and prioritizing traffic on ExtremeWare-based switches. Its central extremeQosRuleTable defines classification patterns per rule — inbound port, IP source/destination address ranges, transport protocol and L4 port ranges, and IP TOS match/mask — each mapped to an extremeQosRuleQosProfileIndex that determines forwarding treatment, along with a live extremeQosRuleCounter of matched packets and an extremeQosRuleRowStatus for rule lifecycle. Scope and direction objects further indicate whether a rule applies to signaled flows (e.g., RSVP) versus inband data traffic. Monitoring it lets operators confirm which QoS classification rules are active and verify hit counts to see whether traffic is actually matching intended rules, and it's deployed on Extreme Networks switches running ExtremeWare's QoS Policy feature — administrators can download the EXTREME-PBQOS-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EXTREME-PBQOS-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

Extreme Networks switches running ExtremeWare (Policy-Based QoS feature)

Monitoring Examples

An operator polls extremeQosRuleTable to check extremeQosRuleCounter for a rule matching a given source/destination address range while extremeQosRuleRowStatus shows active(1); a rule that's active but whose counter never increments would indicate traffic isn't hitting the expected classification pattern, pointing to a misconfigured range or a precedence conflict with another rule.

What Can Be Monitored

QoS rule classification criteria (IP ranges, ports, protocol, TOS)
rule-to-QoS-profile mapping
per-rule matched packet counters
rule row status (active/inactive lifecycle)
next-available rule index for row creation
hardware flow table clear controls

How to Use in IPNetwork Monitor

Example using extremeQosRuleCounter OID:

Select an Extreme Networks switch running ExtremeWare (Policy-Based QoS) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type extremeQosRuleCounter into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of packets matching this QoS rule. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
extremeQosPolicy	1.3.6.1.4.1.1916.1.7			Extreme QoS Policy configuration objects
INT extremeNextAvailableQosRuleIndex	1.3.6.1.4.1.1916.1.7.1	INTEGER	read-only	The value of the next available QoS Rule index. This object is used by an NMS to select an index value for row-creation in the extremeQosRuleTable. The current value of this object is changed to a new value when the current value is written to an agent's table. Row creation using the current value of this object allocates a extremeQosRuleIndex. Note the following: 1. A newly created row does not have to be active(1) for the agent to allocate the extremeQosRuleIndex. 2. Race conditions between multiple NMS's end when a row is created. Rows are deemed created when a setRequest is successfully committed (i.e. the errorStats is noError(0)). 3. An agent that exhausts its supply of extremeQosRuleIndex values returns zero as the value of this object. This can be used by an NMS as an indication to deleted unused rows and reboot the device.
extremeQosRuleTable	1.3.6.1.4.1.1916.1.7.2		not-accessible	Table of QoS policy rules. Entries that duplicate the exact same set of policy conditions are not allowed.
extremeQosRuleEntry	1.3.6.1.4.1.1916.1.7.2.1		not-accessible	Entry in table of QoS policy rules
INT extremeQosRuleIndex	1.3.6.1.4.1.1916.1.7.2.1.1	INTEGER	read-create	An index into the table of QoS policy pattern rules. The index for a manager to use for creating new rows is determined by reading the value of extremeNextAvailableQosRuleIndex.
INT extremeQosRuleScope	1.3.6.1.4.1.1916.1.7.2.1.2	INTEGER	read-create	The scope of conditions in which this rule applies. The value 'signaled' means that the policy rule is applied only to QoS signaling messages e.g. RSVP. The value 'inband' means that the policy rule is applied only to data traffic passing through this node. the value 'any' means that the policy is applied to any of the above conditions. Only the value 'any' is supported in ExtremeWare 6.0.
INT extremeQosRuleDirection	1.3.6.1.4.1.1916.1.7.2.1.3	INTEGER	read-create	The direction in which this rule applies. The value 'forward' means that the rule is applied to data streams in the direction specified by the classification pattern. The value 'backward' means that the rule is applied in the reverse direction. The value 'any' means that the rule is applied for traffic in either direction of data flow. Note that the direction is applied to where the data flow itself will go, not to the direction of any signaling messages e.g. RSVP. Only the value 'forward' is supported in ExtremeWare 6.0.
INT extremeQosRuleInPort	1.3.6.1.4.1.1916.1.7.2.1.4	INTEGER	read-create	The ifIndex value of the physical switch input port for which this rule applies. Rules that indicate an individual value for this object have a lower precedence in ExtremeWare than rules that specify IP patterns. Conversely, rules that use IP patterns must apply to all physical ports and specify a value of 0 for this object. Any attempt to write a rule that indicates an individual value for this object together with non-default values for any of { extremeQosRuleDestAddrStart, extremeQosRuleDestAddrEnd, extremeQosRuleSrcAddrStart, extremeQosRuleSrcAddrEnd, extremeQosRuleProtocol, extremeQosRuleDestL4PortStart, extremeQosRuleDestL4PortEnd, extremeQosRuleSourceL4PortStart, extremeQosRuleSourceL4PortEnd and extremeQosRuleInPortMask } will be rejected by the agent.
POR extremeQosRuleInPortMask	1.3.6.1.4.1.1916.1.7.2.1.5	PortList	read-create	The list of physical switch input ports which further qualifies an IP flow. This object is an octet string with the MSB of octet 0 indicating port 0 and LSB indicating port 7. Similarly, the MSB of octet 1 indicates port 8 and it's LSB indicates port 15 and so on. The port numbers are 0-based. This object has no meaning for rules defined on physical ports that are not associated with an IP flow. Port based rules can be defined by assigning a non zero value to extremeQosRuleInPort. Any attempt to set this value without specifying the source/destination address range and/or source/destination l4 port range will be rejected by the agent. For IP flows that apply to all physical ports in the switch, this will be a zero length octet string.
IP extremeQosRuleDestAddrStart	1.3.6.1.4.1.1916.1.7.2.1.6	IpAddress	read-create	The start of the destination IP address range for which this rule applies.If this object has any value other than the default then this rule takes precedence over any rule that specifies an individual physical input port, a VLAN or any incoming implicit 802.1p traffic class rule. Any attempt to write a rule that indicates a non-default value for this object together with an individual port value for extremeQosRuleInPort will be rejected by the agent.
IP extremeQosRuleDestAddrEnd	1.3.6.1.4.1.1916.1.7.2.1.7	IpAddress	read-create	The end of the destination IP address range for which this rule applies. If this object has any value other than the default then this rule takes precedence over any rule that specifies an individual physical input port, a VLAN or any incoming implicit 802.1p traffic class rule. Any attempt to write a rule that indicates a non-default value for this object together with an individual port value for extremeQosRuleInPort will be rejected by the agent.
IP extremeQosRuleSrcAddrStart	1.3.6.1.4.1.1916.1.7.2.1.8	IpAddress	read-create	The start of the source IP address range for which this rule applies. If this object has any value other than the default then this rule takes precedence over any rule that specifies an individual physical input port, a VLAN or any incoming implicit 802.1p traffic class rule. Any attempt to write a rule that indicates a non-default value for this object together with an individual port value for extremeQosRuleInPort will be rejected by the agent.
IP extremeQosRuleSrcAddrEnd	1.3.6.1.4.1.1916.1.7.2.1.9	IpAddress	read-create	The end of the source IP address range for which this rule applies. If this object has any value other than the default then this rule takes precedence over any rule that specifies an individual physical input port, a VLAN or any incoming implicit 802.1p traffic class rule. Any attempt to write a rule that indicates a non-default value for this object together with an individual port value for extremeQosRuleInPort will be rejected by the agent.
INT extremeQosRuleProtocol	1.3.6.1.4.1.1916.1.7.2.1.10	INTEGER	read-create	The IP protocol number for which this rule applies. If this object has any value other than 'any' then this rule takes precedence over any rule that specifies an individual physical input port, a VLAN or any incoming implicit 802.1p traffic class rule. Any attempt to write a rule that indicates a non-default value for this object together with an individual port value for extremeQosRuleInPort will be rejected by the agent.
L4P extremeQosRuleDestL4PortStart	1.3.6.1.4.1.1916.1.7.2.1.11	L4Port	read-create	The destination starting layer 4 port number that would be used to match an IP flow. The value of 0 means that all layer 4 information would be ignored when matching an IP flow. If this object has any value other than 0 then this rule takes precedence over any rule that specifies an individual physical input port, a VLAN or any incoming implicit 802.1p traffic class rule. Any attempt to write a rule that indicates a non-default value for this object together with an individual port value for extremeQosRuleInPort will be rejected by the agent. Any attempt to write an ICMP rule specifying an IP pattern with a non-default value for this object will be rejected by the agent.
L4P extremeQosRuleSourceL4PortStart	1.3.6.1.4.1.1916.1.7.2.1.12	L4Port	read-create	The source starting layer 4 port number that would be used to match an IP flow. The value of 0 means that all layer 4 information would be ignored when matching an IP flow. If this object has any value other than 0 then this rule takes precedence over any rule that specifies an individual physical input port, a VLAN or any incoming implicit 802.1p traffic class rule. Any attempt to write a rule that indicates a non-default value for this object together with an individual port value for extremeQosRuleInPort will be rejected by the agent. NOTE: For an ICMP rule that specifies an IP pattern, this object has a different meaning in that it specifies the ICMP Type and Code values, in the following manner: The value of the Type must be shifted to the left by 8 bits and logical ORed with the value of the Code. The result will be stored in this object. In this case, this object can only contain values between 0 and 65535 inclusive since the ICMP Type and Code values are limited between 0 and 255 each.
OCT extremeQosRuleTosMask	1.3.6.1.4.1.1916.1.7.2.1.13	OCTET STRING	read-create	A mask for the incoming IP Type-of-Service field to be applied when matching. The value of 0 means that any incoming IP ToS field is ignored. Only the default value is supported in ExtremeWare 6.0.
OCT extremeQosRuleTosMatch	1.3.6.1.4.1.1916.1.7.2.1.14	OCTET STRING	read-create	If the value of the incoming IP Type-of-Service field, after applying a mask of extremeQosRuleTosMask, is this value then this rule is applied. Only the default value is supported in ExtremeWare 6.0.
INT extremeQosRuleQosProfileIndex	1.3.6.1.4.1.1916.1.7.2.1.15	INTEGER	read-create	A pointer into the extremeQosProfileTable indicating the QoS treatment and actions to be applied to traffic matching this rule. A value of 0 means that this traffic will be dropped/discarded. The default value is that this traffic gets the default QoS treatment and actions.
STR extremeQosRuleOwner	1.3.6.1.4.1.1916.1.7.2.1.16	OwnerString	read-create	Indicates the identity of the manager that configured this entry.
ROW extremeQosRuleRowStatus	1.3.6.1.4.1.1916.1.7.2.1.17	RowStatus	read-create	The row status for this QoS rule. This OBJECT can be set to: active(1) createAndGo(4) createAndWait(5) destroy(6) The following values may be read: active(1) notReady(3).
L4P extremeQosRuleDestL4PortEnd	1.3.6.1.4.1.1916.1.7.2.1.18	L4Port	read-create	The destination last layer 4 port number that would determine the l4 port range to match an IP flow. The value of 0 means that all layer 4 information would be ignored when matching an IP flow. If this object has any value other than 0 then this rule takes precedence over any rule that specifies an individual physical input port, a VLAN or any incoming implicit 802.1p traffic class rule. Any attempt to write a rule that indicates a non-default value for this object together with an individual port value for extremeQosRuleInPort will be rejected by the agent. Any attempt to write an ICMP rule specifying an IP pattern with a non-default value for this object will be rejected by the agent.
L4P extremeQosRuleSourceL4PortEnd	1.3.6.1.4.1.1916.1.7.2.1.19	L4Port	read-create	The source last layer 4 port number that would determine the l4 port range to match an IP flow. The value of 0 means that all layer 4 information would be ignored when matching an IP flow. If this object has any value other than 0 then this rule takes precedence over any rule that specifies an individual physical input port, a VLAN or any incoming implicit 802.1p traffic class rule. Any attempt to write a rule that indicates a non-default value for this object together with an individual port value for extremeQosRuleInPort will be rejected by the agent. Any attempt to write an ICMP rule specifying an IP pattern with a non-default value for this object will be rejected by the agent.
INT extremeQosRulePrecedence	1.3.6.1.4.1.1916.1.7.2.1.20	INTEGER	read-create	The precedence used to select one rule over potentially multiple rules that might match an L3/L4 flow. The rule with highest precedence takes precedence over any rule that specifies a matching flow, individual physical input port, a VLAN or any incoming implicit 802.1p traffic class rule. Any attempt to write a rule that indicates a non-default value for this object together with an individual port value for extremeQosRuleInPort will be rejected by the agent.
C64 extremeQosRuleCounterEx	1.3.6.1.4.1.1916.1.7.2.1.21	Counter64	read-only
