Description: Manages Cisco WAN Frame Relay port configuration and operational status on MGX service modules.

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 CISCO-WAN-FR-PORT-MIB?

CISCO-WAN-FR-PORT-MIB is a Cisco enterprise MIB for configuring and monitoring Frame Relay ports on WAN service modules within Cisco MGX multiservice switching platforms, covering logical frame relay ports carried over T1/E1 physical lines. It exposes port configuration groups (line number, DS0 channel bitmap, speed, admin type), port state groups reflecting current operational status, and port counter groups for statistics on frame relay traffic. For monitoring, it lets an administrator confirm a frame relay port's administrative and operational state, check configured line speed and DS0 channelization, and pull traffic statistics to spot congestion or errors on the WAN link, which is core to diagnosing service-affecting problems on carrier frame relay circuits. It builds on standard T1/E1 physical-layer MIBs for the underlying line, since a frame relay port is logically layered on a DS0/T1/E1 channel. It is deployed on Cisco MGX WAN switching platforms used by carriers and enterprises to deliver Frame Relay services over T1/E1 access lines, and network engineers can download the CISCO-WAN-FR-PORT-MIB file directly to load it into their MIB browser for these platforms.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-WAN-FR-PORT-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 MGX WAN switch (Frame Relay service module)

Monitoring Examples

An operator would poll portAdmin and the corresponding operational state from frPortStateGrp for entries in frPortCnfPortGrpTable to confirm a frame relay port is administratively up and passing traffic, cross-checking portDs0ConfigBitMap and portSpeed to verify the correct DS0 channels and line speed are provisioned. If portRowStatus shows a port as active but frPortCntPortGrp statistics show rising errors, that points to a physical-layer or channelization problem on the underlying T1/E1 line rather than a configuration issue.

What Can Be Monitored

  • frame relay port admin/operational state
  • DS0 channel configuration
  • port line speed
  • port type
  • frame relay traffic statistics

How to Use in IPNetwork Monitor

Example using rcvPortFrames OID:

Select a Cisco MGX WAN switch (Frame Relay service module, legacy) 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 rcvPortFrames 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 frames Received on the ingress. 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 (in Frames), 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.
