Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is Nortel-Magellan-Passport-IpCosMIB?

Nortel-Magellan-Passport-IpCosMIB is a Nortel enterprise MIB for the Magellan Passport multiservice switching platform, managing IP class-of-service (CoS) mapping, DSCP marking, and queue assignment for IP traffic traversing the switch. It exposes row-status-controlled configuration tables for CoS policy groups, user assignments to those groups, and policy definitions, all following Nortel's characteristic virtual-router (vr) component-based provisioning model. Its relevance to device monitoring is primarily configuration-status oriented: administrators use it to verify that CoS policy provisioning (row status, component name, storage type) has been correctly applied and is active, which affects how traffic is queued and marked across the switch fabric. It is a Nortel Passport-specific MIB built on the platform's own virtual-router/component provisioning architecture rather than a standard IETF DiffServ MIB, though it serves an analogous CoS/QoS purpose. It is deployed on Nortel Magellan Passport multiservice switches in carrier and large enterprise WAN backbones handling mixed IP/ATM/Frame Relay traffic. Engineers can download the Nortel-Magellan-Passport-IpCosMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-IpCosMIB. 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.

Monitoring Examples

An administrator checks vrIpPgRowStatusTable (vrIpPgRowStatusEntry, keyed by vrIpPgIndex) to confirm a CoS policy group's vrIpPgRowStatus is active rather than stuck in a notReady or notInService state after provisioning. The vrIpPgUsersTable (vrIpPgUsersEntry, vrIpPgUsersValue, vrIpPgUsersRowStatus) is then reviewed to verify the expected set of users/interfaces has been correctly assigned to that CoS policy group, and vrIpPgPolicyRowStatusTable entries are checked to confirm the DSCP marking/queue policy itself is properly instantiated.

U32 vrIpPgCosTreatmentCos	1.3.6.1.4.1.562.2.4.1.100.6.20.3.10.1.1	Unsigned32	read-only	This attribute specifies the Class Of Service (COS) with which a packet would be forwarded when this COS treatment is selected.
INT vrIpPgCosTreatmentSetTosByte	1.3.6.1.4.1.562.2.4.1.100.6.20.3.10.1.3	INTEGER	read-write	This attribute specifies whether the router would change the Type Of Service (TOS) byte of packets when this COS treatment is selected. If set to yes, the TOS byte is changed based on the value of tos and tosMask.
HEX vrIpPgCosTreatmentTos	1.3.6.1.4.1.562.2.4.1.100.6.20.3.10.1.4	Hex	read-write	This attribute specifies the value of the Type Of Service (TOS) byte with which packets are updated when this COS treatment is selected. This attribute is ignored if setTosByte is set to no. The actual TOS byte of the packet is updated based on the tos and tosMask attribute using the following formula: New TOS = ( Original TOS & ~tosMask ) \| ( tos & tosMask ) For example: Original TOS byte: hex 8A (10001010 in binary) tos attribute: hex 12 (00010010 in binary) tosMask attribute: hex 3F (00111111 in binary) The changed TOS byte would be: hex 92 (10010010 in binary).

The mask specifies which bits within the original TOS byte are to be examined or updated by the router. When the setTosByte is set to yes, this attribute is used in conjunction with the tos attribute to determine how the TOS byte is updated using the following formula: New TOS = ( Original TOS & ~tosMask ) \| ( tos & tosMask ) For example: Original TOS byte: hex 8A (10001010 in binary) tos attribute: hex 12 (00010010 in binary) tosMask attribute: hex 3F (00111111 in binary) The changed TOS byte would be: hex 92 (10010010 in binary). When the TosMap component is provisioned under this Policy, this attribute is used in conjunction with the tos attribute of the TosMap component when packets are examined for matching TOS bits. By default, this attribute is set to the value of hex FC, i.e. bits 0-5 of the TOS byte ( differentiated services codepoint bits) are eligible to be examined and updated. When either the setTosByte is set to yes, or when the TosMap component is provisioned, a zero tosMask is considered invalid,
U32 vrIpPgCosTreatmentEmissionPriority	1.3.6.1.4.1.562.2.4.1.100.6.20.3.10.1.6	Unsigned32	read-write	This attribute specifies the emission priority to be assigned to packets when this CoS Treatment is selected. The use of the emission priority is egress media specific. This attribute can take a value from 1 to 8. 1 is treated as the highest priority and 8 the lowest. Some egress media support fewer then 8 emission prioritie. For these media the values which correspond to emission priorities lower then the lowest supported priority are treated as the lowest priority. For instance, if a media supports two priorities, high and normal, a vlaue of 1 corresponds to high priority and values of 2 to 8 correspond to normal priority.
U32 vrIpPgCosTreatmentDiscardPriority	1.3.6.1.4.1.562.2.4.1.100.6.20.3.10.1.7	Unsigned32	read-write	This attribute specifies the discard priority to be assigned to packets when this CoS Treatment is selected. VALUES ( 0 = unChanged )
vrIpPgUsersTable	1.3.6.1.4.1.562.2.4.1.100.6.20.432		not-accessible	This attribute specifies a list of components that are using this CosPolicyGroup.
