I know that Cisco 7200 has function "Service Selection Gateway"(SSG),

I want to enable SSG function and recevie dynamic authortication,

used command as follow :

ssg enable

ssg radius-helper auth-port 3799 acct-port 3780

ssg radius-helper key cisco

then Let Radius Server send RADIUS packets to port 3799,but device respond

"port not reach.",I think because port didn't be opened,

but how does it enable SSG feature? pls which Hero tell me a method.

Hello Simec,

a good reference for SSG


Try with the default ports:


The default port number for acct-port is 1646.

The default port number for auth-port is 1645.

Are you sure RADIUS is using UDP port 3799 when talking to SSG ?

Hope to help

Hi, Giuslar, thank you.

I have been read the guide that you refer.

as I know, between SSG and RADIUS Server,its have some talking ways.

1) In a way, SSG send accountting/authentication Request

(RADIUS packet) to RADIUS Server,

and RADIUS Server respond the Response(RADIUS packet) to SSG.

2)In another way, RADIUS Server send dynamic authorization Request

(RADIUS packet) to SSG,and SSG respond the Response(RADIUS packet)

to SSG.

I want to enable the second way, but it isn't successful.

best regard
