I'm having a problem with discovery of an IPS 4240 running 6.1(1)E1 device on a MARS 20 running 4.3.2. The "Test Connectivity" function returns the following error:
PN-0001:PnLogger message map not initialized
along with a suggestion to verify access by running telnet to port 443 from the MARS CLI (which I've done and it works just fine). I'm receiving events from the IPS just fine, but have an incomplete topology map because of the failed discovery.
I suspected it might have been a certificate validation issue and have regenerated the cert on the IPS and manually validated the new fingerprint on the MARS, and I've tried setting the "name" of the IPS device on the MARS to match the subject of the cert (which seems to be the IP address of the IPS rather than its hostname) to no avail.
Any troubleshooting tips appreciated.
