for a prolonged period. If this situation occurs, contact Brocade’s technical support for assistance.
Removing MAC address entries
You can remove learned MAC address entries from the BigIron RX Series system’s MAC address
table. You can remove the following:
• All MAC address entries
• All MAC address entries for a specified interface module
• All MAC address entries for a specified Ethernet port
• All MAC address entries for a specified VLAN
• A specified MAC address entry in all VLANs
For example, to remove entries for the MAC address 000d.cb80.00d in all VLANs, enter the
following command at the Privileged EXEC level of the CLI:
BigIron RX# clear mac-address 000d.cb80.00d0
Syntax: clear mac-address <mac-address> | ethernet <slot>/<port> | module <slot> | vlan
<number>
If you enter the clear mac-address command without any parameters, the software removes all
MAC entries.
Use the <mac-address> parameter to remove a specified MAC address from all VLANs. Specify the
MAC address in the following format: HHHH.HHHH.HHHH.
Use the ethernet <slot>/<port> parameter to remove all MAC addresses for a specified Ethernet
port. For the <slot> parameter, enter the number of the chassis slot in which the Ethernet interface
module is installed. For the <port> parameter, enter the Ethernet port for which to remove all MAC
addresses.
Use the module <slot> parameter to remove all MAC addresses for an interface module in a
specified chassis slot.
Use the vlan <number> parameter to remove all MAC addresses for a specified VLAN.
