Hello, on a 2960 switch, is the default switchport mode 'dynamic desirable' ?
How can I see what the swtichport mode is. When I do a 'show run' nothing regarding switchport modes is visible ?
Thanks for any help.
Yes, it's the default switch port setting. Cisco device IOSs normally don't display the default setting/command in the show run.
Issue a 'show interface x/x switchport' command to verify on which mode it's in.
