Static MAC Filtering

The commands in this section describe how to configure static MAC filtering. Static MAC filtering allows you to configure destination ports for a static multicast MAC filter irrespective of the platform.

macfilter

This command adds a static MAC filter entry for the MAC address <macaddr> on the VLAN <vlanid>. The value of the <macaddr> parameter is a 6-byte hexadecimal number in the format of b1:b2:b3:b4:b5:b6. The restricted MAC Addresses are: 00:00:00:00:00:00, 01:80:C2:00:00:00 to 01:80:C2:00:00:0F, 01:80:C2:00:00:20 to 01:80:C2:00:00:21, and FF:FF:FF:FF:FF:FF. The <vlanid> parameter must identify a valid VLAN.

The number of static mac filters supported on the system is different for MAC filters where source ports are configured and MAC filters where destination ports are configured.

• For unicast MAC address filters and multicast MAC address filters with source port lists, the maximum number of static MAC filters supported is 20.
• For multicast MAC address filters with destination ports configured, the maximum number of static filters supported is 256.

i.e. For current Tejas Networks platforms, you can configure the following combinations:

• Unicast MAC and source port (max = 20)
• Multicast MAC and source port (max = 20)
• Multicast MAC and destination port (only) (max = 256)
• Multicast MAC and source ports and destination ports (max = 20)
• Format: macfilter <macaddr>< vlanid>
• Mode:Global Config

no macfilter

This command removes all filtering restrictions and the static MAC filter entry for the MAC address <macaddr> on the VLAN <vlanid>. The <vlanid> parameter must be specified as a 6-byte hexadecimal number in the format of b1:b2:b3:b4:b5:b6.

The <vlanid> parameter must identify a valid VLAN.

• Format: no macfilter <macaddr> <vlanid>
• Mode: Global Config

macfilter adddest

Use this command to add the interface or range of interfaces to the destination filter set for the MAC filter with the given <macaddr> and VLAN of <vlanid>. The <vlanid> parameter must be specified as a 6-byte hexadecimal number in the format of b1:b2:b3:b4:b5:b6. The <vlanid> parameter must identify a valid VLAN.

NOTE: Configuring a destination port list is only valid for multicast MAC addresses.

• Format:macfilter adddest <macaddr>
• Mode: Interface Config

no macfilter adddest

This command removes a port from the destination filter set for the MAC filter with the given <macaddr> and VLAN of <vlanid>. The <vlanid> parameter must be specified as a 6-byte hexadecimal number in the format of b1:b2:b3:b4:b5:b6. The <vlanid> parameter must identify a valid VLAN.

• Format: no macfilter adddest <macaddr>
• Mode: Interface Config

macfilter adddest all

This command adds all interfaces to the destination filter set for the MAC filter with the given <macaddr> and VLAN of <vlanid>. The <vlanid> parameter must be specified as a 6-byte hexadecimal number in the format of b1:b2:b3:b4:b5:b6. The<vlanid> parameter must identify a valid VLAN.

NOTE: Configuring a destination port list is only valid for multicast MAC addresses.

• Format: macfilter adddest all <macaddr>
• Mode: Global Config

no macfilter adddest all

This command removes all ports from the destination filter set for the MAC filter with the given <macaddr> and VLAN of <VLANID>. The <VLANID> parameter must be specified as a 6-byte hexadecimal number in the format of b1:b2:b3:b4:b5:b6. The <VLANID> parameter must identify a valid VLAN.

• Format: no macfilter adddest all <macaddr>
• Mode: Global Config

macfilter addsrc

This command adds the interface or range of interfaces to the source filter set for the MAC filter with the MAC address of <macaddr>and VLAN of <vlanid>. The <vlanid> parameter must be specified as a 6-byte hexadecimal number in the format of b1:b2:b3:b4:b5:b6. The <vlanid> parameter must identify a valid VLAN.

• Format: macfilter addsrc <macaddr>< vlanid>
• Mode: Interface Config

no macfilter addsrc

This command removes a port from the source filter set for the MAC filter with the MAC address of <macaddr> and VLAN of <vlanid>. The <vlanid> parameter must be specified as a 6-byte hexadecimal number in the format of b1:b2:b3:b4:b5:b6. The <vlanid> parameter must identify a valid VLAN.

• Format: no macfilter addsrc <macaddr> <vlanid>
• Mode: Interface Config

macfilter addsrc all

This command adds all interfaces to the source filter set for the MAC filter with the MAC address of <macaddr> and <vlanid>. You must specify the <vlanid> parameter as a 6-byte hexadecimal number in the format of b1:b2:b3:b4:b5:b6. The <vlanid> parameter must identify a valid VLAN.

• Format: macfilter addsrc all <macaddr> < vlanid>
• Mode: Global Config

no macfilter addsrc all

This command removes all interfaces to the source filter set for the MAC filter with the MAC address of <macaddr> and VLAN of <vlanid>. You must specify the <vlanid> parameter as a 6-byte hexadecimal number in the format of b1:b2:b3:b4:b5:b6.

The <vlanid> parameter must identify a valid VLAN.

• Format: no macfilter addsrc all <macaddr> <vlanid>
• Mode: Global Config

show mac-address-table static

This command displays the Static MAC Filtering information for all Static MAC Filters. If you specify all, all the Static MAC Filters in the system are displayed. If you supply a value for <macaddr>, you must also enter a value for <vlanid>, and the system displays Static MAC Filter information only for that MAC address and VLAN.

• Format: show mac-address-table static {<macaddr> <vlanid>| all}
• Mode: Privileged EXEC

The display parameters for above command are:

• MAC Address: The MAC Address of the static MAC filter entry.
• VLAN ID: The VLAN ID of the static MAC filter entry.
• Source Port(s): The source port filter set's slot and port(s).

NOTE: Only multicast address filters will have destination port lists.

show mac-address-table static filtering

This command displays the Static Filtering entries in the Multicast Forwarding Database (MFDB) table.

• Format: show mac-address-table staticfiltering
• Mode: Privileged EXEC

The display parameters for above command are:

• VLAN ID: The VLAN in which the MAC Address is learned.
• MAC Address: A unicast MAC address for which the switch has forwarding and or filtering information. As the data is gleaned from the MFDB, the address will be a multicast address. The format is 6 two-digit hexadecimal numbers that are separated by colons, for example 01:23:45:67:89:AB.
• Type: The type of the entry. Static entries are those that are configured by the end user. Dynamic entries are added to the table as a result of a learning process or protocol.
• Description: The text description of this multicast table entry.
• Interfaces: The list of interfaces that are designated for forwarding (Fwd:) and filtering (Flt:).
