I am trying to find out how i can display the up time/down time on Avaya switch ports
I don't know how to show it in the CLI, it's not in the output of
show interfaces verbose or
show port-statistics afaik...
Another option could be to query it using SNMP. Avaya supports the IF-MIB, and the ifTable entries contain an
ifLastChange value (.126.96.36.199.188.8.131.52.1.9):
The value of sysUpTime at the time the interface entered its current operational state. If the current state was entered prior to the last re-initialization of the local network management subsystem, then this object contains a zero value.
Note that this value is in "ticks", or 1/100ths of a second.
