Managing the FastIron GS Chassis

Changing the Chassis Temperature Polling Interval

The software reads the temperature sensor and polls other hardware sensors according to the value set for the
chassis poll time, which is 60 seconds by default. You can change the chassis poll time using the CLI.
To change the chassis poll time, enter a command such as the following at the global CONFIG level of the CLI:
FastIron(config)#chassis poll-time 200
Syntax: chassis poll-time <value>
The <value> can be 0 – 65535.
Displaying Management Module CPU Usage
You can display the amount of the management module’s CPU in use. To do so, enter the following command at
any level of the CLI:
Syntax: show cpu
Removing MAC Address Entries
You can remove learned MAC address entries from the Foundry system’s MAC address table. You can remove the
following entries:
• 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:
FastIron# 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.
