Is there possible to specify the source ip address used for Radius

[kycheong]

I have a cat6509 configured to talk to Radius server (ACS), as I understood that the IP address used by Cat6k to talk to ACS is by using the nearest interface ip, can i explicitly specify the source address used by Cat6k in this case ?

thanks in advance.

I am not clear whether you are asking about talking to Radius from the switch or from the MSFC? If it is from the MSFC you are correct that by default it will use as source address the address of the outbound interface. On the MSFC you can use the command: ip radius source-interface to specify what address to use.

On the switch I think that it will source its packets to Radius using the management/console IP address rather than the outbound interface. So no command is needed to specify the source interface.

Hi, Thanks

I guessed this is the one I'm looking for, but you have mentioned that if it's from Cat6k mgmt interface, then u can't specify it since this interface will be used to talk to Radius.

However, as I'm having Cat6k with native IOS, hence it's gonna be come from the msfc interface then
