7200 ethernet port still up/up after cable removed

[jeremy-keen]

Recently I was very surprised to find an interface status remain up/up after I removed the ethernet cable. The device is a 7206 router with a dual fast ethernet module running IOS 12.2(3). The ethernet port is configure with auto speed and duplex and an IP address (nothing special!) I was hoping the interface would go down and clear the arp cache.

If anyone could explain this, or tell me if it is normal behavior I would much appreciate it.

Many thanks,

Jeremy Keen

Hi,

Is there a "no keepalive" statement ?

This will keep your interface up.

You can remove iit with the interface configuration command "keepalive"

Good luck.
