aaa group server loadbalance?

[KelvinT]

Hello,

Does the "aaa group server radius" command on a switch loadbalance the server or just use the first on the list until it is unavailable?

Example:

aaa group server radius ISE

Server name ISE1

Server name ISE2

Server name ISE3

Thanks

Thanks for your reply.

This document is very useful but somewhat confusing.  So if this feature (load-balancing) isn't enabled does that mean the switch will continue to use server1 until it is unavailable?

Thanks again

Hi there,

The servers are tried in sequence with the subsequent servers acting as a failover backup of the preceding listed server.

If a server does not respond to a request it is marked as 'dead'  (typically for one minute) and the failover server is tried.

cheers,

Seb.

Thanks for your reply.

So if server1 is available does that mean every access attempt uses server1 until it is unavailable or does it do a round robin LB?
