I need to be able to deny a client machine access to the network based on the MAC address of the NIC.
How is this accomplished on a 3750G running 12.2.50 IOS.
Please check this link,
Another simple way,
Switch(config)#mac address-table static 000f.1f43.e62a vlan 8 drop
Below is the explanation of the command:
mac address-table static drop
Use the mac address-table static drop global configuration command on the
switch stack or on a standalone switch to enable unicast MAC address
filtering and to configure the switch to drop traffic with a specific source
or destination MAC address. Use the no form of this command to return to the
mac address-table static mac-addr vlan vlan-id drop
no mac address-table static mac-addr vlan vlan-id
