     Hi all,

The no shutdown command. An interface may be correctly configured and physically connected, yet be "administratively down." In this state it will not function at all.Operational enable state only has something to do with the type of port.

Either access or trunk or none/disable.

Access Ports for clientpc will be (#switchport mode access) and  trunk for uplink to another switch or router(#switchport mode trunk)

This is the output from #show interface

Port is shutdown:


FastEthernet0/1 is administratively down, line protocol is down (disabled)

Port is no shutdown and is not connected

FastEthernet0/2 is down, line protocol is down (notconnect)

Port is no shutdown and is connected

FastEthernet0/3 is up, line protocol is up (connected)

Hope to Help !!

Routing impact wise, there wont be any difference in convergence.

But the status of the both will be different as told in the other thread by Ganesh.

Similarly, doing a no-shut on an interface which is not connected doesnt make any difference other than in the interface status.

btw If you are trying to do some advanced testing for Autoneg or Convergence, do let know the scenario.
