Cabletron Systems 2000 manual The Port Priority ConÞguration Window

The SmartSwitch 2000 Chassis View

Highlight a port, then use the drop-down list box to select a priority (Normal–7).

Click Apply to set the priority at the device. Any priority of 1 or higher will allow packets received at the chosen port to be forwarded from the higher priority transmission queue.

NOTES

In the event that an incoming packet received on a designated port already has a priority associated with it, you can use the ctPriorityExtPortFwdInboundPriority OID to determine whether the incoming priority should remain intact, or be replaced with the priority that you have set for the receiving port.

Use the MIB Tools utility suite to set the ctPriorityExtPortFwdInboundPriority OID to 1 (for the appropriate port instance) if you want the incoming packet to retain its originally set priority when received by the port; set the OID to 2 if you want the packet to take the default priority set for the receiving port. Refer to the SPECTRUM Element Manager Tools Guide for information on using the MIB Tools suite.

To access the Port Priority ConÞguration window:

1.Click on Device to access the Device menu.

2.Click on Priority Configuration, and then select Port Based from the menu. The Port Priority Configuration window will appear.

The Port Priority ConÞguration window displays the contents of the ctPriorityExtPortTable. It has a list box that displays the front panel interfaces supported by the SmartSwitch 2000 device, along with the slot number occupied by the module (for the SmartSwitch 2000, the slot number will always be 1), and any transmit priority that has been assigned to those interfaces.

To assign a transmit priority to a port:

1.Click to highlight the port interface of interest in the Port # column. Each interface is identified by its MIBIIfIndex.
