  • MAC filtering on access layer switches

    MAC filtering on access layer switches

    MAC filtering is a network access control method where a router or switch allows or blocks devices based on their MAC (Media Access Control) address. When a device tries to join a network, the router or access point checks the device's MAC address against the configured filtering. Perhaps filtering inbound and stopping the traffic from traversing your network could work? Here is a support doc that might help with the 3560 mac filtering, using VLAN maps https://www. com/c/en/us/support/docs/switches/catalyst-3550-series-switches/64844-mac-acl-block-arp. In allow.
