ACS Authentication Server not responding: No error

[Rojer-bkk]

Hi Expert,

I use PIX 8.0(4) and ACS 4.2 for VPN authentication. I got error as below even I'm able to ping to ACS server from PIX

RADIUS_SENT erver response timeout

RADIUS_DELETE

ERROR: Authentication Server not responding: No error

I tested aaa command from PIX and check configure on ACS (key and IP address) include restart ACS. The output still timeout and not responding from server. I have no idea why?

PIX config:

=========

aaa-server AAA-VPN protocol radius

aaa-server AAA-VPN (MANAGEMENT) host 172.20.0.9

key xxxxxxx

tunnel-group CGS-DR type remote-access

tunnel-group CGS-DR general-attributes

address-pool VPN-POOL

authentication-server-group AAA-VPN LOCAL

default-group-policy GR-CGS

Thanks

Hi,

The issue was cleared by re-install ACS. Thanks for your feedback
