Switching Enhancements

Release Note

Example To make the queue as long as possible on a switch with 256Mbytes of memory, use the command:

set swi hwr=4000000

set switch port

Description This command modifies the value of parameters for switch ports.

The description parameter can now be entered without a value, to remove an existing description.

The thrashaction parameter specifies the action the router or switch takes when it detects MAC address thrashing on a port. Thrashing occurs when one or more ports repeatedly learn the same MAC addresses, for example, as a result of a network loop.

Take care with the thrashaction parameter because misuse can impair your network operation.

Set the thrashaction parameter to:

none to apply no thrash limiting to the port.

learndisable to disable MAC address learning on the port, until the period specified with the thrashtimeout parameter has elapsed. The default is learndisable.

portdisable or linkdown to disable the port until either the period specified by the thrashtimeout parameter has elapsed, or until the port is re-enabled by using the enable switch port command. If you specify linkdown, the link state is down; if you specify portdisable, the link state remains up.

vlandisable to block all traffic on the VLAN where the address was learned, until either the period specified by thrashtimeout has elapsed, or until the port is re-enabled by using the enable switch port vlan command.

The thrashtimeout parameter specifies the time, in seconds, for which the switch employs the thrash action specified by the thrashaction parameter. The thrashtimeout cannot be set to none if thrashaction=learndisable. If
