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 reached or exceeded the upper threshold. Except IPv4 route prefix entries, all Layer 3 resources have an upper usage threshold of 85%.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.227.2.1.5 Warning equipmentAlarm(5)

Parameters

Name Meaning
OID Indicates the MIB object ID of the alarm.
Threshold Indicates the upper threshold of the layer 3 resource usage.
EntPhysicalindex Indicates the index of the physical entity.
EntPhysicalName Indicates the name of the physical entity.
Slot Indicates the slot ID.
ResourceType Indicates the ID of a Layer 3 resource.
  • hostTablePrefixTable(27) indicates the host route prefix entry.
  • routingTablePrefixTable(28) indicates the IPv4 route prefix entry.
  • ecmpNextHopTable(29) indicates the next hop entry of the equal-cost route.
  • layer3InterfaceTable(30) indicates the Layer 3 outbound interface entry.
  • nextHopTable(31) indicates the next hop entry.
  • tunnelDecapsulationTable(32) indicates the tunnel encapsulation and decapsulation entry.
  • ipv6RoutingTablePrefixTable(47) indicates the IPv6 route prefix entry.

Impact on the System

When the Layer 3 resource usage exceeds the upper threshold, services are not affected. If the usage of all Layer 3 resources reaches 100%, new Layer 3 services are unavailable.

Possible Causes

The Layer 3 resource usage exceeded the upper threshold, or the usage reached 100%.

Procedure

  1. Lower the Layer 3 resource usage.

    • Delete unnecessary host routes, and ND and ARP entries to release host route prefix resources.
    • Delete unnecessary network segment routes to release IPv4 route prefix resources.
    • Delete unnecessary equal-cost routes to release next hop resources.
    • Delete unnecessary Layer 3 interfaces to release Layer 3 interface resources.
    • Delete unnecessary routes including host routes and network segment routes, and ND and ARP entries to release next hop resources.
    • Delete tunnels to release tunnel encapsulation and decapsulation resources.
    • Delete unnecessary network segment routes to release IPv6 route prefix entries.

  2. Collect alarm, log, and configuration information, and contact technical support personnel.
