13. er a 1OBASE T or a 100BASE TX device The Switch offers priority queuing which means all packets that are received are examined to see if they have been priority encoded If a packet has been then the Switch will read the priority level and determine whether the packet should be directed through the normal or high priority channel This feature can be useful for example during excessive loads when one type of traffic may require priority over another The Switch is configured to comply with 802 1p VLAN tagged frames Traffic prioritization ensures that high priority data is forwarded through the Switch without being delayed by lower priority data It differentiates traffic into classes and prioritizes those classes automatically Traffic prioritization uses the multiple traffic queues that are present in the hardware of the Switch to ensure that high priority traffic is forwarded on a different queue from lower priority traffic and is given preference over that traffic This ensures that time sensitive traffic gets the highest level of service The 802 1D standard specifies eight distinct levels of priority 0 to 7 each of which relates to a particular type of traffic The priority levels and their traffic types are shown in the following table Priority Level Traffic Type 0 Best Effort 1 Background 2 Standard spare 3 Excellent Effort business critical 4 Controlled Load streaming multimedia 5 Video Interactive media
