Trying to poll time from Catalyst 2924. PIX is doing this just fine. CSS can ping ip address of the switch and other verse. I can see with debug that requests coming to the switch and ntp packets are sent back.

Can somebody help?

Below is some additional info.

P.S. After reboot and issue sntp server ... command it stay in up state but looks like packets never received and after 180 seconds it goes DOWN.
