How to set up Radius Authentication on N-Series switches

Hi,

I am new to the N-Series platform (and power connect, for that matter) and am trying to set up Radius authentication on an N2024 switch but have had no success.  I can ping the Server, but the server logs show no attempts from this switch.  "show radius statistics" on the switch shows all zreo's as well.  I have no trouble ssh-ing into the switch using the local account.  Here is the config:

username "xxxxx" password xxxxxxxxxxxxxxxxxx privilege 15 encrypted
aaa authentication login "defaultList" radius local
aaa authentication enable "enableList" radius enable
aaa authorization exec "dfltExecAuthList" radius local
radius-server host auth x.x.x.x
primary
name "Default-RADIUS-Server"
key "xxxxxx"


line ssh
exec-timeout 30
enable authentication default
login authentication default

{The last two were entered, but do not show in the config, presumably because they are already the default}

The log show this:

<189> Oct 22 12:00:49 10.199.5.231-1 TRAPMGR[146624324]: traputil.c(740) 29921 %% Failed User Login with User ID: user1
<190> Oct 22 12:00:49 10.199.5.231-1 USER_MGR[146624324]: user_mgr.c(1789) 29920 %% User user1 Failed to login because of authentication failures

Can you go with the defaults, or do you HAVE to set up a Managment list?

Any help would be most appreciated.

Thanks,

Matt
