L3MB_1.3.6.1.4.1.2011.5.25.227.2.1.5 hwBoardL3FwdResLack

Description

L3MB/4/FwdResLack:OID [OID] The layer 3 resource usage has reached or exceeded [Threshold]%.(EntPhysicalindex=[GAUGE],EntPhysicalName=[OCTET],Slot=[OCTET],ResourceType=[INTEGER])

The Layer 3 resource usage reaches or exceeds the upper threshold. Except the IPv4 route prefix entries, all Layer 3 resources have an upper usage threshold of 85%, which cannot be changed.

You can use the fib threshold-alarm command to set the upper threshold of the IPv4 route prefix entries.

By default, the upper threshold of the IPv4 route prefix entries is 85%.

Procedure

  1. Run the display acl resource [ slot slot ] command to view information about ACL resources, including ACL4 and ACL6 resources.
  2. Run the display current-configuration command to check the current configuration on the switch.
  3. Check the services that occupy ACL resources based on ACL resource information and the current configuration as follows, and delete unnecessary services to release ACL resources.

1.3.6.1.4.1.2011.5.25.227.2.3.1 Warning equipmentAlarm (5)

Parameters

Name Meaning
OID Indicates the MIB object ID of the alarm.
Slot=[OCTET] Indicates a slot ID.
ReasonId=[INTEGER]
Indicates an alarm reason ID:
  • nextHopTable(31) l3-forward-entries are abnormal.

Impact on the System

Layer 3 services involved in the alarm may become unavailable.
