Command Usage

• You must configure an ACL mask before you can change frame priorities

based on an ACL 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. To specify this
priority, use the set priority keywords.

• 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. To specify the
IP precedence priority, use the set tos keywords. To specify the DSCP
priority, use the set dscp keywords. 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.
