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-address | ethernet port-num | 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 port-num parameter 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

1 sec avg: 10 percent busy
5 sec avg: 10 percent busy
60 sec avg: 10 percent busy

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).
