Planet Technology MGSW-004 4.10 Priority – 802.1p, 4.11 Priority 2 – TOS (Type of Service), Press, Used Count, Max Allowed MAC Address Count, Max Allowed MAC Address Count per port

there is no MAC address count restriction for that port.

ØType the number in the “ Max Allowed MAC Address Count “ edit for that port. The upper bound of this number is the “ Max Allowed MAC Address Count per port “

ØPress the “ Press “ button

ØThe “ Used Count “ will tell you how many MAC address residing in the corresponding port now.

Note: A trunked port is not allowed to enable the port security option.

4.10 Priority – 802.1p

There are two priority queues (high and low) on each port. Each port arbitrates between two transmit queues (high and low priority).

The arbitration uses weighted round-robin between the high and low priority queues, and you can adjust this weight.

Programmable Mapping of 802.1p to Internal Priority

The received packets with 802.1q tag are assigned priority according to a flexible and programmable mapping of the 802.1p user-priority tag (3 bits, value from 0 to 7) to the internal priority queue. The default is to assign a packet to high priority queue when the 802.1p user-priority tag is 4 to 7, and to low priority queue when the 802.1p user-priority tag is 0 to 3. Please check the corresponding mapping checkbox to assign a high priority or uncheck that to assign a low priority.

4.11 Priority 2 – TOS (Type of Service)

Each port can parse the header of an incoming IPv4 header and identify the Type-Of-Service byte (TOS field). This is extremely important with the deployment of Microsoft Windows 2000 and the emerging DiffServ standard, which marks Voice-Over-IP and other real-time traffic using this field. This feature provides Quality of Service (QoS).
