Problem con int Loop1 on 3550

luisk2 · ‎07-17-2002

I had a problem with loopback int in a 3550-48-EMI, i had created one of them and now i can delete it, i use the no int loop1command in config mode and it doesn´t work. And now i had 3 int loop1 on the switch??? and i can delete none of them. Some idea??

Thanks.

I have got the same problem on 3550-24-EMI. I've solve it by reloading the switch, but it's not the best solution.

What software version are you running on the 3550? I tried in a lab switch running 12.1(9)EA1c and did not see this issue

3550 Release Notes:

* CSCdx29360

If you create multiple loopback interfaces by using the loopback interface 0 global configuration command, you cannot delete the loopback interfaces by using the no interface loopback 0 command.

The workaround to delete the loopback interfaces is to reload the switch by using the reload privileged EXEC command.

I was right only reload may solve the problem.

Yes, if i reload it i can delete that multiple loop1 interfaces.

I had software version Version 12.1(8)EA1c.

By the moment i'll use the reload to solve this problem and i'll be care when configuring loopback interfaces.

Thanks for your help.
