lecTopologyChange

Module: LAN-EMULATION-CLIENT-MIB

OID (symbolic): LAN-EMULATION-CLIENT-MIB::lecTopologyChange

OID (numeric): 1.3.6.1.4.1.353.5.3.1.1.2.1.9

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-only

Description: C19 Topology Change. Boolean indication that the LE Client is using the Forward Delay Time C18, instead of the Aging Time C17, to age non-local entries in its LE_ARP cache C16.

For a client which is not connected to the LES, this object is defined to have the value 'false'.

What is lecTopologyChange?

This read-only boolean OID indicates whether the LE Client is currently using the shorter Forward Delay Time instead of the normal Aging Time to age non-local LE_ARP entries, which happens during a topology-change period; it's always false for a client not connected to the LES.

Examples

Walk all instances (SNMPv2c):
