Symptom

When doing default interface on a N9K-C92348GC-X switch on impacted code, you may see the following error. There may be unexpected config left on the port as a result. switch(config)# default int e1/51 Interface config wipeout failed. Please check "show default-interface log" for error details << reported error switch(config)# show run int e1/51 !Command: show running-config interface Ethernet1/51 !Running configuration last done at: Fri Dec 22 14:17:39 2023 !Time: Fri Dec 22 14:17:52 2023 version 10.2(4) Bios:version 05.44 interface Ethernet1/51 link mac-up timer 0 <<< unexpected added config after default link max-bringup timer 0 <<< unexpected added config after default RAD-AC4-RR-HH(config)# default interface e1/51 Interface config wipeout failed.

Conditions

N9K-C92348GC-X switch default interface on a physical port impacted code

Workaround

Manually delete the remaining config lines on a defaulted port using "no" CLI: no link mac-up timer 0 no link max-bringup timer 0 "reload" or "reload ASCII" will not clear these lines, they must be manually deleted.
