To delete an entry:

1.Highlight the entry line in the current active entries list that you wish to delete.

2.Click Delete to remove the redirect pair you have highlighted from the current active entries list.

The entry will be deleted from the current active entries list and the traffic from the source port will not be redirected to the destination port any longer.

Priority Configuration

The SmartSwitch 2000 devices support priority packet forwarding. Priority packet forwarding lets you designate certain packets to be of higher importance than others, thereby allowing for the forwarding of these packets before packets of lower priority. This functionality is essential for time-critical applications — such as real-time video — on shared networks.

NOTE

The Priority Configuration menu option will only appear in the Device menu for devices that respond to any of NetSight Element Manager’s queries to the following OIDs: ctPriorityExtPortStatus, ctPriorityExtMaxNumMACEntries, or ctPriorityExtNumPktTypeEntries. If your device’s firmware does not respond to these queries, contact the Global Technical Assistance Center for upgrade information.

Frame priority is enabled by the “tagging” of MAC frames so that they are given a priority designation when they are forwarded by the SmartSwitch 2000 device — which is a tag-aware switch (i.e., one that adheres to the IEEE P802.1p and IEEE P802.1q Draft Standards). Tagging a frame is accomplished by adding a Tag Header to a frame immediately following its original Destination and Source MAC address fields (and any routing fields, if present), and then recomputing the Frame Check Sequence (FCS) appropriately. On receiving such a frame, a tag-aware switch will read the priority from the tagged portion of the frame, remove the Tag Header, recompute the FCS, and then direct it to its appropriate transmission queue.

There are eight priority levels — indicated 0 through 7— available to designate user priority. Frames tagged with a 0 represent the lowest priority level (or normal) traffic, and frames tagged with a 7 indicate the highest priority level traffic.

The SmartSwitch 2000 itself supports two transmission queues: one that is for 0 or normal priority traffic (or any non-tagged traffic), and a second queue that is reserved for frames that have been tagged with a priority level of 1 or higher. On receiving any priority-tagged frames, the SmartSwitch 2000 will forward them out of the high priority queue before forwarding any frames in the normal priority queue. However, the SmartSwitch 2000 will tag outgoing frames with the full range of eight priority levels, so that upon reception, a device that supports the entire range of priority queuing will forward the frame appropriately.
