Configuring Layer-2 Address Filters

Chapter 10: Security Configuration Guide

If you want to control access to a source or destination on a per-MAC address basis, you can configure an address filter. Address filters are always configured and applied to the input port. You can set address filters on the following:

•A source MAC address, which filters out any frame coming from a specific source MAC address.

•A destination MAC address, which filters out any frame destined to specific destination MAC address.

•A flow, which filters out any frame coming from a specific source MAC address that is also destined to a specific destination MAC address.

To configure Layer-2 address filters, enter the following commands in Configure mode:

Configure a source MAC based	filters add address-filter name <name>
address filter.	source-mac <MACaddr> vlan <VLAN-
	num> in-port-list<port-list>

Configure a destination MAC based	filters add address-filter name <name>
address filter.	dest-mac<MACaddr> vlan <VLAN-
	num> in-port-list<port-list>

Configure a Layer-2 flow address	filters add address-filter name <name>
filter.	source-mac <MACaddr> dest-mac
	<MACaddr> vlan <VLAN-num> in-
	port-list<port-list>

Configuring Layer-2 Port-to-Address Lock Filters

Port address lock filters allow you to bind or “lock” specific source MAC addresses to a port or set of ports. Once a port is locked, only the specified source MAC address is allowed to connect to the locked port and the specified source MAC address is not allowed to connect to any other ports.

To configure Layer-2 port address lock filters, enter the following commands in Configure mode:

Configure a port address lock filter.

filters add port-address-lock name

<name> source-mac<MACaddr> vlan <VLAN-num> in-port-list<port-list>
