Cisco Bug: CSCuq27342 - Traceback and reload triggered by failover configuration
Apr 16, 2020
- Cisco ASA 5500-X Series Firewalls
Known Affected Releases
9.1(3) 9.1(4.5) 9.2(2.8)
<B>Symptom:</B> When configuring a failover interface using the command "failover lan interface <name> <interface>" on ASA5585, the ASA might crash with a traceback and reload. The crash would occur righter after the software responds and executes the code for setting up the failover interface. If a crash occurs during normal system operation then it is not due to this bug. <B>Conditions:</B> Configure a failover interface using the "failover lan interface <name> <interface>" command. The chances of a crash are statistically very low, but may increase if traffic into the CPU from network interfaces is high. In lab testing it was only reproducible on a single instance of 5585 and using ASDM with an HTTP interface to the device to send over the configuration commands. In theory though it could occur through console CLI configuration as well.
