Sending CDRs to two Radius servers simultaneously

[kerbachi_m]

Hello,

I want to send CDR's (vsa) to two Radius servers, I have added this to AS5350 gateway :

GW(config)# radius-server host 10.0.0.1 auth-port 1612 acct-port 1618 key rad1

GW(config)# radius-server host 10.1.1.1 auth-port 1812 acct-port 1813 key rad2

GW(config)# radius-server vsa send accounting

GW(config)# radius-server vsa send authentication

The problem is : the GW is sending CDRs to the first Radius only !. I want to send CDRs to two radius simultaneously.

What is wrong with my config ?

Thanks in advance.

Thanks thomas.chen,

I tried to apply it to my gw:

as5400(config)#aaa group server radius billing

as5400(config-sg-radius)#server 1.1.1.1 auth-port 1700 acct-port 1701 ?

auth-port UDP port for RADIUS authentication server (default is 1645)

there is no "key" command, how can do to specify a radius secret key for eatch radius server ?

Thank you in advance.
