Block port TCP 5061 on L2 switch

Michael Turkstra · ‎03-05-2015

Dear all

I need to block port 5061 TCP for a number of users.

When i want to do this in a 2960 switch and i want to apply it gives the error %ERROR: Port-based ACLs are not supported with this image

my ACL is:

access-list 100 deny tcp any any eq 5061
access-list 100 permit ip any any

Interface fa0/1
access-list 100 in
%ERROR: Port-based ACLs are not supported with this image

the Main switch is a 3560.

I was thinking to add a ACL there on uplink interface ??

ip access-list extendend TEST
deny tcp host 192.168.1.1 eq 5061 any
permit ip any any

Interface fa0/1
ip access-group TEST in

Does anyone know what is the best option.

Best for me would be if i could block on interface of the 2960 switch.
Just need to block TCP 5061

Thanks!!

Layer 2 switches don't know how to look at ports.

You need to find a Layer 3 device, like a router or a Layer 3 core switch.

TCP 5061 = SIP (over TLS) protocol. You sure you want to do this?
