Description: Huawei switch Layer 2 multicast address management extensions MIB for per-VLAN multicast group filtering policies.
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 HUAWEI-SWITCH-L2MAM-EXT-MIB?
HUAWEI-SWITCH-L2MAM-EXT-MIB is a Huawei enterprise MIB extending Layer 2 MAC-address management functionality on Huawei switches, specifically adding per-VLAN multicast group filtering policy objects. It exposes configuration data describing which multicast MAC addresses or groups are permitted or filtered on a per-VLAN basis, rather than raw traffic counters. Its monitoring value is primarily configuration verification: confirming that multicast filtering policies applied per VLAN match intent, which matters for controlling unwanted multicast flooding in switched networks. It extends the base Layer 2 MAC-address management MIB on the same platform and is used together with standard bridge/VLAN MIBs. Deployment context is Huawei Layer 2/Layer 3 switches in campus or metro networks running multicast services such as IPTV, where HUAWEI-SWITCH-L2MAM-EXT-MIB SNMP monitoring confirms per-VLAN multicast filtering policy matches intent.
IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-SWITCH-L2MAM-EXT-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
- Huawei Layer 2/Layer 3 switch
Monitoring Examples
An administrator would inspect the per-VLAN multicast filtering policy objects to confirm a given VLAN correctly permits or blocks specific multicast groups, and an unexpected filtering entry would explain why a multicast stream (e.g., an IPTV channel) is not reaching subscribers on that VLAN.
What Can Be Monitored
- per-VLAN multicast filtering policy
- MAC address management entries
- multicast group permissions
