Description: The aging time of each entry in the path MTU discovery table.

What is zyPathMtuDiscoveryExpiredTime?

This object reports the remaining aging time for a specific entry in the IPv6 Path MTU Discovery table before that discovered MTU value is dropped and needs to be re-probed. An administrator reads this to understand how long the switch will keep using a previously discovered path MTU before re-verifying it. For example, a low zyPathMtuDiscoveryExpiredTime value for a busy path means the switch will soon need to re-run path MTU discovery for that destination.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.890.1.15.3.36.1.1.1.4
snmpwalk -v2c -c public <target> ZYXEL-IPV6-PATH-MTU-MIB::zyPathMtuDiscoveryExpiredTime

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.890.1.15.3.36.1.1.1.4.1
snmpget -v2c -c public <target> ZYXEL-IPV6-PATH-MTU-MIB::zyPathMtuDiscoveryExpiredTime.1
