H3C-EVC-MIB

Description: H3C MIB for Ethernet Virtual Connection (EVC) service management in carrier Ethernet network deployments.

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.

H3C-EVC-MIB is an H3C proprietary MIB for managing Ethernet Virtual Connections (EVCs), the Metro Ethernet Forum concept of a logical point-to-point or multipoint Ethernet service instance carried over a provider network. It exposes per-port service instance capability and limits, plus a service instance table keyed by service instance ID, holding encapsulation type/rule and associated S-VLAN ID range for each EVC. This is primarily a service-configuration MIB, letting an administrator verify how many service instances a port supports and whether encapsulation/VLAN mappings are correctly provisioned, which is important for diagnosing Carrier Ethernet service faults. It aligns conceptually with Metro Ethernet Forum EVC concepts though it is an H3C-proprietary implementation with its own object structure rather than a direct IETF standard mapping. It is deployed on H3C carrier/metro Ethernet switches and routers offering Ethernet Virtual Connection services. Engineers can download the H3C-EVC-MIB file directly to load it into their MIB browser.

An operator would poll h3cEvcSrvInstTable/h3cEvcSrvInstEntry (indexed by h3cEvcSrvInstId) to check h3cEvcSrvInstEncap and the h3cEvcSrvInstSvlanIdListLow/High range, confirming a service instance is correctly mapped to its expected S-VLAN range. h3cEvcPortMaxSrvInstNum tells the operator how many more service instances a given port can still support before hitting the configured limit.
