Use the bridge address interface configuration command to add a static MAC-layer station source address to the bridge table. To delete the MAC address, use the no form of the bridge address command (using the no form of the command without specifying a MAC address deletes all static MAC addresses belonging to this VLAN).
bridge address mac-address {ethernet interface | port-channel port-channel-number} [permanent | delete-on-reset | delete-on-timeout | secure]
no bridge address [mac-address]
No static addresses are defined. The default mode for an added address is permanent.
Interface Configuration (VLAN) Mode
There are no user guidelines for this command.
The following example adds a permanent static MAC-layer station source address on a port to the bridge table.
Console (config-if)# bridge address 168.210.0.10 ethernet 1/e8 permanent |
Use the bridge aging-time global configuration command to set the address table aging time. To restore the default, use the no form of the command.
bridge aging-time seconds
no bridge aging-time
The default is 300 seconds.
Global Configuration Mode
There are no user guidelines for this command.
The following example sets the bridge aging time.
Console (config)# bridge aging-time 250 |
Use the clear bridge privileged EXEC command to remove any learned entries from the forwarding database.
clear bridge
This command has no default configuration.
Privileged EXEC Mode
There are no user guidelines for this command.
The following example clears the bridge tables.
Console# clear bridge |
Use the show bridge address-table privileged EXEC command to display dynamically created entries in the bridge-forwarding database.
show bridge address-table [vlan vlan] [ethernet interface | port-channel port-channel-number]
This command has no default configuration.
Privileged EXEC Mode
There are no user guidelines for this command.
The following example displays all classes of entries in the bridge-forwarding database.
Use the show bridge address-table privileged EXEC command to display statically entered entries in the bridge-forwarding database.
show bridge address-table static [vlan vlan] [ethernet interface | port-channel port-channel-number]
This command has no default configuration.
Privileged EXEC Mode
There are no user guidelines for this command.
The following example displays all classes of entries in the bridge-forwarding database.
Console# show bridge address table static
Aging time is 300 sec
vlan mac address port type ---- -------------- ----- ----- 200 0010.0D48.37FF 5/9 delete-on-reset |
Use the port security interface configuration command to disable new address learning on an interface. To enable new address learning, use the no form of the command.
port security [forward | discard | discard-shutdown] [trap seconds]
no port security
Port security is disabled.
Interface Configuration (Ethernet, port-channel) Mode
There are no user guidelines for this command.
The following example disables the learning of new addresses on a port. All frames with unlearned source addresses are discarded.
Console (config)# interface ethernet 1/e8 Console (config-if)# port security discard |
Use the show ports security privileged EXEC command to display the port-lock status.
show ports security [ethernet interface | port-channel port-channel-number]
This command has no default configuration.
Privileged EXEC Mode
There are no user guidelines for this command.
The following example displays all classes of entries in the port-lock status.
Use the bridge multicast filtering global configuration command to enable filtering of multicast addresses. To disable filtering of multicast addresses, use the no form of the command.
bridge multicast filtering
no bridge multicast filtering
Disabled. All multicast addresses are flooded to all ports of the relevant VLAN.
Global Configuration Mode
If multicast routers exist on the VLAN and IGMP snooping is not enabled, use the bridge multicast forward-all command to forward all multicast packets to the multicast routers.
The following example enables bridge multicast filtering.
Console (config)# bridge multicast filtering |
Use the bridge multicast address interface configuration command to register MAC-layer multicast addresses to the bridge table, and adds static ports to the group. To unregister the MAC address, use the no form of the bridge multicast address command.
bridge multicast address {mac-multicast-address | ip-multicast-address}
bridge multicast address {mac-multicast-address | ip-multicast-address} {add | remove} {ethernet interface-list | port-channel port-channel-number-list }
no bridge multicast address {mac-multicast-address | ip-multicast-address}
No multicast addresses are defined.
Interface Configuration (VLAN) Mode
If the command is executed without add or remove, the command only registers the group in the bridge database.
Static multicast addresses can only be defined on static VLANs.
The following example registers the MAC address.
Console (config)# interface vlan 8 Console (config-if)# bridge multicast address 0100.5e02.0203 |
The following example registers the MAC address and adds ports statically.
Console (config)# interface vlan 8 Console (config-if)# bridge multicast address 0100.5e02.0203 add ethernet 1/e1-9, 2/e2 |
Use the bridge multicast forbidden address interface configuration command to prevent adding a specific multicast address to specific ports. To reconfigure the default value, use the no form of this command.
bridge multicast forbidden address {mac-multicast-address | ip-multicast-address} {add | remove} {ethernet interface-list | port-channel port-channel-number-list }
no bridge multicast forbidden address {mac-multicast-address | ip-multicast-address}
No forbidden addresses are defined.
Interface Configuration (VLAN) Mode
Register the multicast group before you define the forbidden ports.
The following example forbids the MAC address on port 2/e9 within VLAN 8.
Console (config)# interface vlan 8 Console (config-if)# bridge multicast address 0100.5e02.0203 Console (config-if)# bridge multicast forbidden 0100.5e02.0203 add ethernet 2/e9 |
Use the bridge multicast forward-all interface configuration command to forbid a port to be a Forward-all-multicast port. To restore the default, use the no form of the bridge multicast forward-all command.
bridge multicast forward-all {add | remove} {ethernet interface-list | port-channel port-channel-number-list}
no bridge multicast forward-all
Disables forward-all on all ports
Interface Configuration (VLAN) Mode
There are no user guidelines for this command.
The following example forwards all multicast packets on port 1/e8.
Console (config)# interface ethernet 1/e8 Console (config-if)# bridge multicast forward-all add ethernet 1/e8 |
Use the bridge multicast forbidden forward-all interface configuration command to forbid a port to be a Forward-all-multicast port. To restore the default, use the no form of this command.
bridge multicast forbidden forward-all {add | remove} {ethernet interface-list | port-channel port-channel-number-list}
no bridge multicast forward-all
By default, this setting is disabled (for example, forwarding to the port is not forbidden).
Interface Configuration (VLAN) Mode
IGMP snooping dynamically discovers multicast router ports. When a multicast router port is discovered, all the multicast packets are forwarded to it unconditionally. This command prevents a port to be a multicast router port .
The following example forbids forwarding all multicast packets to port 1/e6.
Console (config)# interface ethernet 1/e8 Console (config-if)# bridge multicast forbidden forward-all add ethernet 1/e6 |
Use the show bridge multicast address-table privileged EXEC command to display multicast MAC address table information.
show bridge multicast address-table [vlan vlan-id] [address mac-multicast-address | ip-multicast-address] [format ip | mac ]
This command has no default configuration.
Privileged EXEC Mode
There are no user guidelines for this command.
The following example displays multicast MAC address table information.
Use the show bridge multicast filtering privileged EXEC command to display the multicast filtering configuration.
show bridge multicast filtering vlan-id
This command has no default configuration.
Privileged EXEC Mode
There are no user guidelines for this command.
The following example illustrates the multicast configuration.
Console # show bridge multicast filtering 1 Filtering: Enabled VLAN: 1 Port Forward-All Static Status ------ --------- ------ 1/e1 Forbidden Filter 1/e2 Forward Forward(s) 1/e3 - Forward(s) |
