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-addresscommand 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

1sec avg: 10 percent busy

5sec avg: 10 percent busy

60sec avg: 10 percent busy

300sec avg: 10 percent busy

Syntax: show cpu
