MAC address issue

Hi All,

 

Need some help on the below issue :

Switch WS-C3850-48P, stack of 3.

 

I wanted to add a MAC address to the MAC access list but messed up:

 

I used >> mac access-list extended Allowed-User-MAC-ACL-IN permit xxxx.xxxx.xxxx ffff.ffff.ffff any

 

Now I am seeing the below in the MAC ACL :

 

permit any host 0000.0000.0000

 

I tried to remove but it still shows in the MAC ACL.

 

Any idea how to remove this?

Re: MAC address issue

Hello

If you want to specify a mac host then you need to tell the acl that, what you have specified is an any any statement with ffff.ffff.ffff any


try this:
mac access-list extended Allowed-User-MAC-ACL-IN
permit host xxxx.xxxx.xxxx any



kind regards
Paul

Re: MAC address issue

Hi Paul,

 

Yes, I have fixed that but I am unable to remove the below from my ACL IN and ACL OUT :

 

permit any host 0000.0000.0000

 

When I do a no permit any host 0000.0000.0000 it doesn't remove this from the ACL.

 

How to remove this and what will this do if I don't remove this as I a not sure whats this line for?

 

Any advice or solution

 

Appreciate it.

Re: MAC address issue

Hi,

It may be a bug in the version IOS you are running. I tried the same exact command on a 3850 and it works just fine.

Also, after negating it, maybe a reboot can fix that but that is not really a permanent solution. If a reboot does not take care of it than an IOS upgrade may do it.
