Cisco Bug: CSCuq15480 - ST: MDSNG switchover - lldp logging level missing from running config
Sep 20, 2019
- Cisco MDS 9000 Series Multilayer Switches
Known Affected Releases
6.2(11)FM(0.13) 6.2(21) 8.2(0)SK(0.114)
Symptom: The Link Layer Discovery Protocol (LLDP) logging level changes will not save from the running configuration to the startup configuration. This can be seen in the switch# show running-config diff output: <pre> switch# sh run diff *** Startup-config --- Running-config *************** *** 9,19 **** feature fport-channel-trunk feature telnet no feature http-server feature lldp logging level aaa 6 - logging level lldp 6 logging level monitor 6 </pre> This condition persists even after erasing the start-up configuration with write erase and performing another copy running-config startup-config command. It also persists when reloading the switch with an existing startup-configuration. Conditions: This issue occurs when the supervisor that booted as the standby supervisor becomes the active supervisor and the LLDP logging level configuration is changed.
