CISCO-VLAN-GROUP-MIB

Description: Manages Cisco VLAN groups that map VLANs to policy groups for simplified VLAN administration.

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.

CISCO-VLAN-GROUP-MIB is a Cisco Catalyst switch MIB for VLAN Group Mapping, a feature that groups multiple VLANs under a single named group for simplified policy application (such as applying QoS or access policy to a whole group rather than each VLAN individually). It exposes a configuration table mapping group names to VLAN membership bitmaps spanning up to 4000+ VLANs, along with row-creation/storage-type controls. This is primarily a configuration-plane MIB rather than a runtime performance/fault MIB, so its monitoring value is in verifying that VLAN group membership matches intended network policy and catching unintended additions/removals of VLANs from a group. It depends on the standard VLAN numbering model (IEEE 802.1Q) that underlies Cisco's Catalyst VLAN infrastructure. It is deployed on Cisco Catalyst switches using VLAN groups to simplify multi-VLAN policy administration. Network engineers evaluating or troubleshooting this functionality can download the CISCO-VLAN-GROUP-MIB file directly to load it into their MIB browser.

cvgConfigTable/cvgConfigEntry exposes cvgConfigGroupName alongside cvgConfigVlansFirst2K and cvgConfigVlansSecond2K bitmaps identifying exactly which VLANs (1-4094) belong to a named group. An admin comparing the live bitmap against the intended VLAN list can catch configuration drift, such as a VLAN accidentally left out of (or included in) a policy group, and cvgConfigRowStatus shows whether a group entry is active or being modified.

Cisco MIB for managing VLAN groups and grouping policies, enabling dynamic configuration and monitoring of Virtual LANs and their associated membership rules on Cisco switches.
