I am looking for a command to list all unused ports for a long period of time. I have tried different combinations but not not getting complete info, none of them listing the interface
sh int | i GigabitEthernet* | Port*.down
Port down for 244 day(s) 1 hour(s) 16 minute(s) 47 second(s)
sh int | i int | Port*.down
