Command Usage
•
You must configure an ACL mask before you can change priorities
based on a rule.
•
Traffic priorities may be included in the IEEE 802.1p priority tag. This
tag is also incorporated as part of the overall IEEE 802.1Q VLAN tag.
The 802.1p priority may be set for either Layer 2 or IP frames.
•
The IP frame header also includes priority bits in the Type of Service
(ToS) octet. The Type of Service octet may contain three bits for IP
Precedence or six bits for Differentiated Services Code Point (DSCP)
service. Note that the IP frame header can include either the IP
Precedence or DSCP priority type.
•
The precedence for priority mapping by this switch is IP Precedence
or DSCP Priority, and then 802.1p priority.
