What Is CISCO-SWITCH-MULTICAST-MIB?

CISCO-SWITCH-MULTICAST-MIB is a Cisco Systems, Inc. proprietary MIB managing Multicast Switching (hardware multicast-packet replication) on Cisco Layer 2/3 devices, covering both ingress-only and ingress+egress replication models across VPNs/VRFs. Its objects cover MVPN hardware-switching status, VRF-Lite status, mroute/processor consistency-check flags, a replication-capability table, a replication-config table (address type, current mode, auto-detect flag), a global replication-mode object, an MVRF-stats table (name, total/partial/RPF-miss flows), and Bidir-PIM DF (Designated Forwarder) usage counters and per-MVRF usage table. As a configuration/performance MIB it lets an administrator confirm hardware multicast-replication mode and watch per-VRF multicast flow counts on a Cisco switch. It is deployed on Cisco Systems Layer 2/3 switching equipment (multicast switching). Engineers can download the CISCO-SWITCH-MULTICAST-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-SWITCH-MULTICAST-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

  • Cisco Systems Layer 2/3 switching equipment (multicast switching)

Monitoring Examples

An administrator checks cswmMvrfTotalFlows and cswmMvrfPartialFlows to watch multicast flow-setup health per VRF on a Cisco switch.

What Can Be Monitored

  • hardware multicast-replication mode and per-VRF flow counts

How to Use in IPNetwork Monitor

Example using cswmFlowResultPackets OID:

Select a Cisco Catalyst switch (Layer 2/3 switching platforms) 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 cswmFlowResultPackets 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 total number of multicast traffic packets forwarded for this flow. 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 Counter64-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.
