Brocade Communications Systems FCX Series User Manual

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

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

Hardware maintenance schedule
FCX 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).
Replacing a copper or fiber optic module
You can remove an SFP from a slot and replace it with a new one while the FastIron CX is powered on
and running.
This section provides information about the following tasks:
• Removing a copper or fiber optic module
• Installing a new copper or fiber optic module
• Cabling a fiber optic module
