5 Removing MAC address entries

Removing MAC address entries

You can remove the following types of learned MAC address entries from the system MAC address table:

•All MAC address entries

•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 00.00.00 in all VLANs, enter the following command at the Privileged EXEC level of the CLI:

Brocade# clear mac-address 00.00.00

Syntax: clear mac-address mac-addressethernet port-numvlan number

If you enter the clear mac-addresscommand without any parameters, the software removes all MAC entries.

Use the mac-addressparameter to remove a specified MAC address from all VLANs. Specify the MAC address in the following format: HHHH.HHHH.HHHH.

Use the ethernet port-numparameter to remove all MAC addresses for a specified Ethernet port. Use the vlan number parameter to remove all MAC addresses for a specified VLAN.

Displaying Brocade ICX 6650 CPU usage

You can display the amount of the CPU in use. To do so, enter the show cpu command at any level of the CLI:

Brocade# show cpu

31 percent busy, from 3248 sec ago

1sec avg: 10 percent busy

5sec avg: 10 percent busy

60sec avg: 10 percent busy

300sec avg: 10 percent busy

Syntax: show cpu

Hardware maintenance schedule

Brocade ICX 6650 switch hardware components require minimal maintenance. Brocade recommends cleaning the fiber-optic connectors on a fiber-optic port and the connected fiber cable each time you disconnect the cable.

You can replace the copper and fiber optic modules (SFPs or mini-GBICs).
