Description: Manages the MPLS signaling and forwarding aspects of pseudowire connections including LDP and RSVP bindings.

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-IETF-PW-MPLS-MIB?

CISCO-IETF-PW-MPLS-MIB is a Cisco module that extends the IETF-derived pseudowire (PW) MIB framework to describe the MPLS-specific signaling and forwarding aspects of pseudowire connections, an area central to Cisco's MPLS/Carrier Ethernet transport technology. It complements CISCO-IETF-PW-MIB (Cisco's implementation of the pseudowire emulation edge-to-edge model) by adding attributes specific to running pseudowires over an MPLS packet-switched network, such as LDP or RSVP label bindings used to establish the PW tunnel. It is used to monitor the software/protocol status of pseudowire signaling, letting an operator confirm a given PW's MPLS label bindings and signaling-protocol state are correctly established and operational, which is essential for detecting pseudowire connectivity or signaling failures. It has an explicit dependency on CISCO-IETF-PW-MIB, whose generic pseudowire table this module augments with MPLS-specific detail. It is typically deployed on Cisco MPLS provider-edge (PE) routers using pseudowires (e.g., Layer 2 VPN/AToM) to carry customer Layer 2 traffic across an MPLS core. Engineers can download the CISCO-IETF-PW-MPLS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-IETF-PW-MPLS-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 MPLS provider-edge (PE) routers

Monitoring Examples

No specific object names were available in the extracted sample for this module, so a table/attribute-level monitoring walkthrough cannot be honestly constructed here. In general use, this MIB would extend the CISCO-IETF-PW-MIB pseudowire table with MPLS-specific label-binding and LDP/RSVP signaling-state information for each configured pseudowire, letting an operator confirm a PW's MPLS signaling has come up correctly.

What Can Be Monitored

  • MPLS pseudowire label bindings
  • LDP signaling state for pseudowires
  • RSVP signaling state for pseudowires
