Configuring Layer-2 Static Entry Filters

Static entry filters allow or force traffic to go to a set of destination ports based on a frame's source MAC address, destination MAC address, or both source and destination MAC addresses in flow bridging mode. Static entries are always configured and applied at the input port. You can set the following static entry filters:

•Source static entry, which specifies that any frame coming from source MAC address will be allowed or disallowed to go to a set of ports

•Destination static entry, which specifies that any frame destined to a specific destination MAC address will be allowed, disallowed, or forced to go to a set of ports

•Flow static entry, which specifies that any frame coming from a specific source MAC address that is destined to specific destination MAC address will be allowed, disallowed, or forced to go to a set of ports

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

Configure a source static	filters add static-entry name <name>
entry filter.	restriction allowdisallowforce source-
	mac <MACaddr> vlan <VLAN-num> in-port-
	list <port-list>out-port-list <port-list>
Configure a destination static	filters add static-entry name <name>
entry filter.	restriction allowdisallowforce dest-
	mac <MACaddr> vlan <VLAN-num> in-port-
	list <port-list> out-port-list<port-list>

Configuring Layer-2 Secure Port Filters

Secure port filters block access to a specified port. You can use a secure port filter by itself to secure unused ports. Secure port filters can be configured as source or destination port filters. A secure port filter applied to a source port forces all incoming packets to be dropped on a port. A secure port filter applied to a destination port prevents packets from going out a certain port.

You can combine secure port filters with static entries in the following ways:

•Combine a source secure port filter with a source static entry to drop all received traffic but allow any frame coming from specific source MAC address to go through

•Combine a source secure port filter with a flow static entry to drop all received traffic but allow any frame coming from a specific source MAC address that is destined to specific destination MAC address to go through

•Combine a destination secure port with a destination static entry to drop all received traffic but allow any frame destined to specific destination MAC address go through
