Description: An Enterasys Networks extension to the MGMD MIB, covering configuration of IGMP/MLD snooping and multicast group management.

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 ENTERASYS-MGMD-EXT-MIB?

ENTERASYS-MGMD-EXT-MIB is a proprietary Enterasys Networks extension covering Multicast Group Membership Discovery (MGMD, i.e., IGMP and MLD snooping) configuration beyond what standard IETF multicast MIBs provide. It exposes global configuration objects (revision string, group-table sizing limits) and a per-interface table controlling IGMP/MLD query behavior, fast-leave processing, and the ability to clear learned multicast groups. Its monitoring value is multicast-service configuration and capacity status: an administrator can check how many multicast groups are currently learned against the configured minimum/maximum/default group-table size, and confirm per-interface query and fast-leave settings, which helps diagnose multicast streaming issues (e.g., a group table hitting its maximum and dropping new group memberships). It is explicitly described as going beyond standard IETF multicast MIBs, implying it complements but does not replace them. It is deployed on Enterasys/Extreme Networks switches handling IPTV or other multicast-heavy traffic where IGMP/MLD snooping behavior needs fine vendor-specific tuning. Engineers can download the ENTERASYS-MGMD-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ENTERASYS-MGMD-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

Enterasys/Extreme Networks switch (multicast/IGMP-MLD snooping capable)

Monitoring Examples

An administrator troubleshooting a multicast video stream that suddenly stops for some subscribers would check etsysMgmdExtConfigNumberOfGroups against etsysMgmdExtConfigMaxNumberOfGroups to see if the switch's group table is full, and review etsysMgmdExtConfigFullAction to understand what the switch does when that limit is reached (e.g., reject new joins). Per-interface, etsysMgmdExtInterfaceTable/etsysMgmdExtInterfaceEntry would be checked via etsysMgmdExtInterfaceQueryEnableState and etsysMgmdExtInterfaceFastLeaveState to confirm IGMP querying and fast-leave are enabled as expected on the access port, and etsysMgmdExtInterfaceClearGroups could be invoked to force-clear a stuck multicast group entry during troubleshooting.

What Can Be Monitored

current number of learned multicast groups
configured min/max/default group table size
per-interface IGMP/MLD query enable state

How to Use in IPNetwork Monitor

Example using etsysMgmdExtStatsCntrsNumV1QueriesSent OID:

Select an Enterasys Networks switch (legacy, later Extreme Networks) (IGMP/MLD snooping extensions) 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 etsysMgmdExtStatsCntrsNumV1QueriesSent 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 version 1 queries this device has sent out. 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 Counter32-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.

Example: If this set has protocols(bits) 1 and 5 set to a '1', and the classification is 'multicastData', this will force IGMP to treat received frames with IP protocol ids of 1 and 5 as 'multicast data', and forward those frames to IGMP joined clients. Similarly if ids 1 and 5 were set to 'routing protocol' then IGMP would treat received frames with these ids as routing protocols, etc.
