The VRF SNMP Setting determines the polling intervals that are used by MPLS Manager to monitor VRFs. MPLS Manager monitors the VRFs by probing the SNMP tables on the PE or multi-VRF CE devices that are hosting the VRFs.

VRF SNMP Setting parameters and their values lists the VRF SNMP Setting parameters.

Table 1. VRF SNMP Setting parameters and their values






Default: ENABLED

Enables or disables:

  1. The MPLS Manager polling of VRF data.

  2. The subsequent analysis of the polled data to determine the status of VRFs.


30 to 3600 seconds

Default: 240 seconds

Sets the time between successive polls.


0 to 10 retries

Default: 3

Sets the number of retry polls to perform when the initial poll fails.


10 to 10000 milliseconds

Default: 700 milliseconds

Sets the amount of time to wait for the poll response before the first poll request times out. The timeout value doubles for each successive retry.

For Timeout=700 msec (0.7 sec) and Retries=3:

  • 0.7 seconds for first retry

  • 1.4 seconds for second retry

  • 2.8 seconds for third retry

For the VRF SNMP Setting, MPLS Manager uses the values polled from the discovered PE or multi-VRF CE devices when analyzing VRFs, including the values for MaxRoutes and MidRouteThreshold.
