Syntax: access-list num (100-199) permit tcp any any 802.1p-priority-marking priority value (0-7) [

internal-priority-marking value (0-7) ]

For UDP

device(config)#acc 105 per udp any any 802.1p-priority-marking 1

or the following command, which also assigns an optional internal-priority-marking value.

device(config)#acc 105 per udp any any 802.1p-priority-marking 1 internal-priority-

marking 5

Syntax: access-list num (100-199) permit udp any any 802.1p-priority-marking priority value (0-7) [

internal-priority-marking value (0-7) ]

In each of these examples, in the first command the internal-priority value is not specified, which means

it maintains a default value of 1 (equal to that of the 802.1p value). In the second command, the

internal-priority value has been configured by the user to 5.

Using an ACL to change the forwarding queue

The 802.1p-priority-marking priority value (0 - 7) parameter re-marks the packets of the 802.1Q traffic

that match the ACL with this new 802.1p priority, or marks the packets of the non-802.1Q traffic that

match the ACL with this 802.1p priority, later at the outgoing 802.1Q interface.

The 802.1p priority mapping is shown in the Default mapping of forwarding queues to 802.1p priorities

table.

The internal-priority-marking value (0 - 7) parameter assigns traffic that matches the ACL to a specific

hardware forwarding queue (qosp0 - qosp7).

NOTE

The internal-priority-marking parameter overrides port-based priority settings.On the FCX platform,

using either 802.1p-priority-marking or 802.1p-priority-marking with internal-priority-marking

performs both marking and internal prioritization.

In addition to changing the internal forwarding priority, if the outgoing interface is an 802.1Q interface,

this parameter maps the specified priority to its equivalent 802.1p (CoS) priority and marks the packet

with the new 802.1p priority. The following table lists the default mappings of hardware forwarding

queues to 802.1p priorities on the FSX.

The complete CLI syntax for 802.1p priority marking and internal priority marking is shown in Extended

numbered ACL configuration on page 112 and Extended named ACL configuration on page 118. The

following shows the syntax specific to these features.
