Cisco Bug: CSCvv89841 - The FMC WebUI "Whois" lookup is timing out
Sep 30, 2020
- Sourcefire Defense Center
Known Affected Releases
6.5.0 6.6.0 6.7.0
Symptom: It is possible for the FMC WebUI (Analysis -> Whois) command window to perform a slow lookup for the IP address because the FMC system wants to make the "whois" request to the internet server the processes these request by first using IPv6 addressing if possible even though the system administrator did not fully configured IPv6 on the box. The command succeeds, but not as quickly as possible because the FMC does not first attempt using IPv4 even though this would be the expected behavior since IPv6 was not configured. Conditions: The FMC management port is not in an IPv6 environment and the FMC management port has not explicitly disabled all IPv6 support.
