Description: Adds Cisco-specific TE tunnel attributes and performance statistics to the IETF MPLS Traffic Engineering MIB.

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-MPLS-TE-STD-EXT-MIB?

CISCO-MPLS-TE-STD-EXT-MIB is a Cisco extension to the IETF MPLS-TE-STD-MIB, adding Cisco-specific managed objects for MPLS Traffic Engineering (TE) tunnels on Cisco routing platforms. Its principal content is the auto-bandwidth feature, which lets an MPLS TE tunnel automatically resize its reserved bandwidth to match measured load, exposing configuration thresholds along with adjustment, overflow, and underflow parameters. From a monitoring standpoint it supports watching software-level tunnel behavior -- the current auto-bandwidth status, and how close a tunnel's actual load is to its overflow/underflow thresholds -- to catch tunnels that are chronically over- or under-provisioned. It explicitly extends the standards-based MPLS-TE-STD-MIB (IETF) and is meant to be used alongside it rather than standalone. It is deployed on Cisco MPLS-TE-capable routers in service-provider and large enterprise WAN/MPLS backbones that use dynamically adjusted TE tunnel bandwidth. Engineers can download the CISCO-MPLS-TE-STD-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-MPLS-TE-STD-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

  • Cisco routers/label switch routers running MPLS Traffic Engineering (auto-bandwidth extension to MPLS-TE-STD-MIB)

Monitoring Examples

cmplsTunnelAutoBWTable/cmplsTunnelAutoBWEntry rows (keyed per TE tunnel) expose cmplsTunnelAutoBWStatus, cmplsTunnelAutoBWMin, and cmplsTunnelAutoBWMax so an operator can confirm auto-bandwidth is enabled and see its allowed range. Polling cmplsTunnelAutoBWAdjThreshPercs/BW alongside cmplsTunnelAutoBWOverflowThreshPercs/BW and cmplsTunnelAutoBWOverflowLimit reveals whether a tunnel is repeatedly hitting its overflow threshold -- a sign that its configured max bandwidth is too low for actual traffic. cmplsTunnelAutoBWUnderflowThreshPercs/BW would similarly flag a tunnel that is over-provisioned relative to its real load.

What Can Be Monitored

  • auto-bandwidth enable status per tunnel
  • min/max auto-bandwidth range
  • overflow/underflow threshold and limits
  • bandwidth adjustment thresholds

How to Use in IPNetwork Monitor

Example using cmplsTunnelAutoBWApplications OID:

Select a Cisco MPLS-TE routers/label switch router 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 cmplsTunnelAutoBWApplications 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. This object indicates the number of auto bandwidths applied. 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.
