Radius Server Port Config on 3750V2

[johnlloyd_13]

hi all,

i'm trying to configure the line below on a 3750V2 but the switch doesn't accept it.

i could see the 3560 supports this command.

is there an alternate command for the 3750 similar to the one seen on a 3560?

3750V2(config)#radius-server source-ports 1645-1646

                      ^

% Invalid input detected at '^' marker.

(config)#radius?

% Unrecognized command

3750V2(config)#do sh ver | i IOS

Hi John,

I only have one c3750v2, and this one is running a pretty old IOS:

Switch Ports Model              SW Version            SW Image                

------ ----- -----              ----------            ----------              

*    1 52    WS-C3750V2-48TS    12.2(50)SE5           C3750-IPBASEK9-M

However, it shows the radius-server options in the context-sensitive help. But it looks like I've to use the radius-server host command to set the source-ports:

Sw(config)#radius-server source-ports ?

  extended  Use 200 source-ports between 21645-21844

Sw(config)#radius-server source-ports extended ?

Sw

(config)#radius-server host 1.1.1.1 auth-port ?

  <0-65535>  Port number

Hi Rolf,

Thanks for the reply! It looks like I need to downgrade to be able to support the said command.
