Displaying PowerConnect B-FCX CPU usage

Changing the temperature polling interval
The software reads the temperature sensor and polls other hardware sensors according to the
value set for the poll time, which is 60 seconds by default. You can change the poll time using the
CLI.
To change the poll time, enter a command similar to the following at the global CONFIG level:
PowerConnect(config)# chassis poll-time 2 200
Syntax: chassis poll-time <stack-id><value>
The <stack-id> can be 1 – 8
The <value> can be 0 – 65535.
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 000d.cb80.00d in all VLANs, enter the
following command at the Privileged EXEC level of the CLI:
PowerConnect# clear mac-address 000d.cb80.00d0
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 PowerConnect B-FCX CPU usage
You can display the amount of the PowerConnect B-FCX CPU in use. To do so, enter the show cpu
command at any level of the CLI:
PowerConnect# show cpu
31 percent busy, from 3248 sec ago
1 sec avg: 10 percent busy
5 sec avg: 10 percent busy
60 sec avg: 10 percent busy
300 sec avg: 10 percent busy
Syntax: show cpu
