COA max number servers

How many ISE server can I configure under the command "aaa server radius dynamic-author" in IOS? I'm using a C3560 with 12.2.55 SE10.

I believe it is eight (8) but

I believe it is eight (8) but I don't remember the exact number. How many do you need? 🙂

Thank you for your reply Neno

I need at least 5 but at this time the config will not let me more than 4.

Sorry for the delayed

Sorry for the delayed response! I tested this in my lab and I was able to configure way more than 4:

aaa server radius dynamic-author
client 192.168.40.100 server-key 7 xxxx
client 192.168.40.101 server-key 7 xxxx
client 192.168.40.111 server-key 7 xxxx
client 192.168.40.112 server-key 7 xxxx
client 192.168.40.113 server-key 7 xxxx
client 192.168.40.114 server-key 7 xxxx
client 192.168.40.115 server-key 7 xxxx
client 192.168.40.116 server-key 7 xxxx
client 192.168.40.117 server-key 7 xxxx
client 192.168.40.118 server-key 7 xxxx
client 192.168.40.119 server-key 7 xxxx
client 192.168.40.120 server-key 7 xxxx

I am using a 2960-C switch running 15.0(2)SE6

I am guessing this is a software limitation. Thus, I would suggest upgrading one of the switches to the latest recommended 15.x version and then try again.

I hope this helps!
