I removed certain radius server hosts from the cisco switches I have and added new hosts radius server hosts - I used this command as follows:
radius-server host "ipaddress" auth-port 1812 acct-port 1813 key /password/
My question is:
1. The auth-port 1812 and the acct-port 1813 - do I have to make sure these ports are open on the new servers or somewhere else? (firewall?).
2. Also, how can I make sure that the new radius server hosts I added are actually "working"? That they are actually authenticating with the radius server correctly?
Once I can verify that all is working and it is set up correctly then I can proceed to make the system wide changes. Basically all I did was a show running-config and copy and pasted the command and just changed the ip address to add the new radius hosts. So I dont know how the auth and acct ports play a role and if there is something I still need to manually configure on the 2008 server or firewall etc.
