How to lock the specified MAC address on the port? (port security + network-access mac-filter) Follow
The following is the example on ES3510MA.
Exception: allow port 1 to learn only the MAC addresses specified in the mac-filter.
Here's the configuration:
Setting "network-access mac-filter"
Console(config)#network-access mac-filter 2 mac-address 00-E0-4C-68-01-5A
Console(config)#network-access mac-filter 2 mac-address B8-AE-ED-BB-08-6F
Console(config)#interface ethernet 1/1
Console(config-if)#port security //"enable port security"
Console(config-if)#port security max-mac-count 3 //"allow port 1 could learn three MAC-Address"
Console(config-if)#network-access port-mac-filter 2 //"MAC-Address-Table only learn MAC-Address which I setting."
Check port security.
Ping from switch to PC1, PC2, PC3.
Capture the packet from PC3.
PC3 could receive ARP Request packet from switch, and reply ARP Reply to switch.
Since I set the mac-filter on the switch, that's why switch didn't learn the PC3's MAC, and ping failed.
