Datapath bridge table age.

Aruba Employee
Q:

What is the age for datapath bridge table and when does Controller flushes those entries?



A:

If Controller has to send any unicast packet to the client, it has to look-up it's bridge table entry to find the Client's mac before it can forward any packet. The age for datapath bridge table entry is 8 minutes. If no traffic received from the client(s) on Controller datapath, their entry from datapath bridge table will be cleared after 8 minutes.

 

Bridge table entry can be viewed from "show datapath bridge table" and to validate if there are any traffic hitting Controller's datapath, "show datapath session table <client ip>" can be used.

 

(Master-Controller) #show datapath  bridge table
