EX4500 mac table grows to limit, all mac ages are 0

$
0
0

I'm hoping someone can point me in the right direction.

 

I have a few devices on my network that create new (bogus?) mac addresses every few seconds. I haven't figured out why, but this is secondary.

 

The top switch in that room is an EX4500 which sits above all switches in the room. It's all layer2, lots of vlans. All downstream interfaces are ae with lacp.

 

Anyway, when I do "show ethernet-switching table", the age of all mac addresses is 0 (or zero for googlability).

 

Why?

 

This being the case, this means that my mac-table-aging-time is never going to work right?

 

The reason I ask is because my mac table is filling up and I have to manually clear it once in a while because of these machines generating new macs every few seconds.

 

What can I do?
