Description (partial)

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:

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
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.

This issue occurs when the supervisor that booted as the standby supervisor becomes the active supervisor and the LLDP logging level configuration is changed.
