such as video or audio data, where latency can produce distorted sounds and images. Packets in the low priority queue will not be processed unless the High priority queue is empty. Setting the port priority to High will deliver all packets arriving at the port to the high priority queue, a Low setting will send them all to the low priority queue. The Normal setting causes the port to examine the packet for an IEEE 802.1p/q priority tag. If no tag exists, the packet will be sent to the low priority queue. If the priority tag field in the packet header contains a value of 0-3, the packet will be placed in the low priority queue; a value of 4-7 causes the packet to be placed in the high priority queue.

♦Port Lock When Enabled, automatic learning for all stations connected to this port will stop and entries in the Forwarding Table for all devices residing on this port will age out. The only traffic this port will allow is traffic from machines whose MAC address is manually entered in the Static Forwarding Table.

♦Broadcast Storm Rising Action This setting will be activated when a Broadcast Storm Rising Threshold is met. When triggered, the port can be configured to Do Nothing, Blocking or Blocking-Trap. The Do Nothing setting causes the switch to operate normally, in other words, ignore the broadcast storm condition. The Blocking setting causes the port to drop all broadcast frames, thus isolating the broadcast storm. Blocking-Trapperforms the same action as Blocking, except it also sends a trap to the designated Trap Recipient informing them of the situation. For more information on broadcast storms, please refer to the previous chapter.

♦Broadcast Storm Falling Action This setting will be activated when the Broadcast Storm Rising Threshold and then the Broadcast Storm Falling Threshold are each met. This setting can be configured to Do Nothing, Forwarding or Forwarding-Trap. The Do Nothing setting causes the switch to operate normally, that is, to ignore the situation. If the port had met the Broadcast Storm Rising Action criteria and started Blocking broadcast packets, it will continue doing so. The Forwarding setting causes the port to begin forwarding broadcast frames, thus removing the Blocking state imposed by the Broadcast Storm Rising Action. Forwarding-Trapperforms the same action as Forwarding, except it also sends a trap to the designated Trap Recipient informing them of the situation.

Press CTRL+S to let the changes take effect. If you wish these changes to be the default for the switch, return to the main menu and choose Save Changes.

STP Port State (whether the Spanning Tree Protocol is enabled or disabled on this port) and Status reflect the current conditions of the port. They are read-only fields and cannot be changed.

Configure Trunk

Ports on the Switch can be grouped together in a single logical port called a trunk. This is discussed in detail in the Port Trunking section of the “Switch Management Concepts” chapter of this manual.

To set up a trunk group, choose Configure Trunk on the System Configuration menu. The following screen appears:
