CheckPoint 6500 channel-group to Cisco Nexus 9Ks VPC

I have a pair of CheckPoint 6500 appliances, GAIA R80.10. Each appliance is connected to a pair of Cisco Nexus 9k switches using a VPC port-channel. Thus I have a channel-group on each firewall consisting of two slave interfaces with the IP address on the bond interface. I am using 802.3ad (LACP) and jumbo frames (9216).

Essentially, the bond interface is DOWN on the appliances, but UP on the Cisco N9ks.

As you can see, the Cisco port-channel is UP,  but the CheckPoint bond interface is DOWN.  I have tried both the L2 and L3+4 transmit hash policy setting, MTU 1500, and both LACP rate of fast and slow with no difference. 

This should really be very simple and there should be no reason why this bond interface should be down, but I'm looking for any suggestions on what the problem could be and what I'm missing.

By the way, I do have a ticket open with CheckPoint tech support, but with no solution so far.

I'd be curious if you ever got a reply to this. We are seeing something similar in another environment

We had a similar issue after upgrading CP 15600 two member cluster running r77.30 to r80.20

In our case the bond interface was flapping due to CCP packets not being received on the bond interfaces.

The issue could be resolved by changing the cluster from multicast mode to unicast mode.


This was not an option for our three member clusters where multicast was required so, with no resolution to the issue, we elected to break the bond and use a single interface.



Did you see this sk? Seems like there may be a known Cisco bug.

It seems the workaround is to change the cluster mode to broadcast.

@Daniel_Taney - yes, thanks but seen that one. Unfortunately, we're running Cisco OTV across geographical sites so broadcast mode can't be implemented in our infrastructure.

Try to upgrade to R80.20 and set cluster mode to unicast
