I have a couple of hosts on a remote network which are infected with a Trojan and various other malware. The hosts themselves are on a DHCP network and I would like to block access from these hosts using a MAC filter.
Is this possible on 12.4(24)T2?
I have another option where I could configure a DHCP process and assign an IP address based on the MAC and essentially black whole the host with an ACL but I'm wondering if there is an easier approach.
Integer from 700 to 799 that you select for the list.
Permits the frame.
Denies the frame.
48-bit MAC addresses written as a dotted triple of four-digit hexadecimal numbers. The ones bits in the mask argument are the bits to be ignored in address.
No MAC address access lists are established.
This command was introduced.
This command was integrated into Cisco IOS Release 12.2(33)SRA.
This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
Configuring bridging access lists of type 700 may cause a momentary interruption of traffic flow.
The following example assumes that you want to disallow the bridging of Ethernet packets of all Sun workstations on Ethernet interface 1. Software assumes that all such hosts have Ethernet addresses with the vendor code 0800.2000.0000. The first line of the access list denies access to all Sun workstations, and the second line permits everything else. You then assign the access list to the input side of Ethernet interface 1.
