ASA5520 CSC-SSM Failover Sync Problems

ifbnetworkops — Mon, 11 Mar 2019 23:08:40 GMT

Hi,

I have a pair of ASA5520, each has a CSC-SSM module, all specs and licences match and the ASA failover between active and passive firewalls works as expected. However, I am unable to get the two content modules to sync. ASA are running 8.4... and attach diagram show cabling. Each CSC-SSM uses it's connected port as a gateway, although I've tried using both primary and standby IP.

When I try to sync the devices as per the Trend Micro instructions I get the error:

"InterScan for CSC SSM could not establish a connection with the failover peer device. Please verify network connectivity with the peer and that the peer is functioning properly, then try again."

All interfaces are up/up. I cannot see the other CSC-SSM in either ASA's arp table. Neither CSC-SSM can ping the other, and none of the guides I've found so far details the pre sync config of the CSC-SSMs. Any help will be greatly appreciated!

Thank you for responding. This was the manual I followed, however it doesn't outline the cabling between the ASA and CSC-SSM's, or the IP addressing. So I've configured each device as I would for a stand alone ASA & module, the problem being that the two CSC-SSM have no path to talk to each other, there is no layer 2 or 3 path between them. I have considered introducing a switch between them to allow a layer 2 path, but I would have thought that if this were part of the product design from Cisco it would have been mentioned in the documentation?

Thanks again.

Hello,

The CSC module got to be on the same subnet than the ASA ( THE CSC will use the ASA as the default gateway)

Can you confirm if you have it like that?
