ibmOsaExpATMForwardDelayTime

Module: IBM-OSA-MIB

OID (symbolic): IBM-OSA-MIB::ibmOsaExpATMForwardDelayTime

OID (numeric): 1.3.6.1.4.1.2.6.188.1.7.1.31

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: Forward Delay Time. The maximum time that a LE Client will maintain an entry for a non-local MAC address in its LE_ARP cache in the absence of a verification of that relationship, as long as the Topology Change flag C19 is true. ibmOsaExpATMForwardDelayTime SHOULD BE less than ibmOsaExpATMAgingTIme. When it is not, ibmOsaExpATMAgingTime governs LE_ARP aging. This time value is expressed in seconds. Corresponds to Initial State Parameter C18.

What is ibmOsaExpATMForwardDelayTime?

The Forward Delay Time (4-30 seconds), the maximum time a non-local MAC address entry is kept in the ARP cache without re-verification while a Topology Change is in effect; this should be less than ibmOsaExpATMAgingTime, otherwise the aging time governs instead.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2.6.188.1.7.1.31
snmpwalk -v2c -c public <target> IBM-OSA-MIB::ibmOsaExpATMForwardDelayTime

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2.6.188.1.7.1.31.1
snmpget -v2c -c public <target> IBM-OSA-MIB::ibmOsaExpATMForwardDelayTime.1
