Last link flap missing from 'show interface' details | ASR9K

[DandelionQueen]

I have an up/up interface on an ASR9K that doesn't have any "Last Link flapped" info while other interfaces on the same router/linecard do. Doing a stare and compare and not finding any configuration or hardware differences that would explain why one interface gives uptime data and another doesn't. Has anyone seen this before? Is there anything that can be done to correct this?

Hello @DandelionQueen ,

interface Te0/5/0/3 has a last link flapped of 5 years and 15 weeks.

can you check the node uptime using a show version ?

interfaceTe0/5/0/1  has no info about the last link flap.

It might be the sign the interface is up from the last system reload that should be more then 5 years ago.

May I ask you why both interfaces have the same IP internet address of 192.168.0.1/16 are they in different VRFs ?

Or you have modified the output  before posting for hiding the real IP addresses ?

Hope to help

Giuseppe
