I am using a MAC access list on this switch, so I go about it by first creating the MAC access list:
#conf t #mac access-list extended aclname # permit host XXXX.XXXX.XXXX any
Then, I tie this list to all/one port:
#conf t #interface gigabit 1/0/Y # mac access-group aclname in
So, any traffic coming towards port Y gets checked against the MAC access list, to check if the source is allowed to enter.
Then i do a
#clear mac address-table dynamic
I have done this to many site offices, but there is this particular site which has about 80+ devices that is driving me crazy, this site has a larger number of devices than the rest sites. So everytime i add a mac, another device gets disconnected.
I guess my question is: Is there any limitation on this access list? How many? How do you propose I overcome this?
