Overview of Installation and Conﬁguration

Setting 802.1p Priority, ToS, and OverridesSetting 802.1p Priority, ToS, and Overrides

802.1p priority is the priority in the tag in the frame header. Switches can use the 802.1p priority.

ToS is the IP precedence in the IP header. Switches ignore ToS. Routers may use it.

The Priority Override Levels for Outbound Trafﬁc are as follows:

CONF_PRI IP_HEADER CONF_TOS

Your speciﬁed priority will be used.

IP header ToS will be converted to 802.1p priority. Your speciﬁed ToS value will be converted to 802.1p priority according to the values shown in Table 2-1.

The ToS Override Levels for Inbound Trafﬁc are as follows:

IP_HEADER	ToS value in the IP header will be used.
ETHER_HEADER Ether header 802.1p priority will be
	converted to ToS value.
CONF_TOS	ToS speciﬁed by user will used.
CONF_PRI	Your speciﬁed 802.1p priority will be converted
	to ToS.
