[c-nsp] etherchannel cisco to checkpoint VSX

[selamat pagi]

Hi

We are experiencing an issue with the  etherchannel  between a cisco
3750 and checkpoint VSX.

The channel comes up but no traffic is passing through.   (not even
ping between the directly connected interfaces is sucessful)
On both boxes is ARP shown as incomplete).

On the switch side we trested with channel mode
 - active (LACP) and
 - mode on

- CP is configured with LACP

Anyone had a similar experience ?

cheers, keti
