11.3 QoS Technical Reference

This section provides some technical background information about the topics covered in this chapter.

11.3.1 IEEE 802.1p

IEEE 802.1p specifies the user priority field and defines up to eight separate traffic types. The following table describes the traffic types defined in the IEEE 802.1d standard (which incorporates the 802.1p).

Table 29 IEEE 802.1p Priority Level and Traffic Type

LEVEL

Level 7 Typically used for network control traffic such as router configuration messages.

Level 6 Typically used for voice traffic that is especially sensitive to jitter (jitter is the variations in delay).
