Feb 17, 2018
- Cisco ASA 5500-X Series Firewalls
Known Affected Releases
Symptom: "write standby" command may fail to synchronize configuration from active ASA to standby ASA. The following error messages may be printed on the standby unit: Beginning configuration replication from mate. ERROR: open(np/port/ec/40/10/23/24/25/26/-1/-1/-1/-1/-1/-1/-1/-1/-1/-1/-1/-1) failed. ERROR: open(Po11) failed. ERROR: Failed to initialize interface inside ERROR: Add interface failed. if "debug fover fail" is enabled. This causes all "nameif" commands being lost from context configuration and standby configuration becomes unsynchronized with active: Number of interfaces on Active and Standby are not consistent. If the problem persists, you should disable and re-enable failover on the Standby. Conditions: ASA 8.4(3.9). Exact conditions are not known yet.
