Effects on 802.1p Quality of Service

BLADEOS 6.5.2 Application Guide

While CEE is off (the default), the G8124 allows 802.1p priority values to be used for Quality of Service (QoS) configuration (see page 133). 802.1p QoS default settings are shown in Table 16, but can be changed by the administrator.

When CEE is turned on, 802.1p QoS is replaced by ETS (see “Enhanced Transmission Selection” on page 204). As a result, while CEE is turned on, the 802.1p QoS configuration commands are no longer available on the switch (the menu is restored when CEE is turned off).

In addition, when CEE is turned on, prior 802.1p QoS settings are replaced with new defaults designed for use with ETS priority groups (PGIDs) as shown in Table 16:

When CEE is on, the default ETS configuration also allocates a portion of link bandwidth to each PGID as shown in Table 17:

PGID	Typical Use	Bandwidth

2	LAN	10%

3	SAN	50%

4	Latency-sensitive LAN	40%
