BLADEOS 6.5.2 Application Guide

802.1p priority values may be assigned by the administrator for a variety of purposes. However, when CEE is turned on, the G8124 sets the initial default values for ETS configuration as follows:

In the assignment model shown in Figure 23 on page 205, priorities values 0 through 2 are assigned for regular Ethernet traffic, which has “best effort” transport characteristics.

Priority 3 is typically used to identify FCoE (SAN) traffic.

Priorities 4-7 are typically used for latency sensitive traffic and other important business applications. For example, priority 4 and 5 are often used for video and voice applications such as IPTV, Video on Demand (VoD), and Voice over IP (VoIP). Priority 6 and 7 are often used for traffic characterized with a “must get there” requirement, with priority 7 used for network control which is requires guaranteed delivery to support configuration and maintenance of the network infrastructure.

Note – The default assignment of 802.1p priority values on the G8124 changes depending on whether CEE is on or off. See “Turning CEE On or Off” on page 192 for details.
