Replacing 802.1p Priority Information in Transmitted Packets
The qos remark command, in Global Configuration mode, changes the 802.1p priority of
each tagged outgoing packet as it leaves the switch, by assigning an 802.1p priority level to
each transmission queue. All tagged packets leaving the switch through this queue are re-
marked with the specified priority.
NOTE The switch does not change the VLAN Priority Tag (VPT) for a switched packet that comes
with an 802.1Q tag, since it assumes that the sender of the packet has already determined
the VPT.
Packets received without a tag have their VPT set by the command qos remark.
Table 18-3 shows the default re-marking of queues to 802.1p priority levels.
Command Syntax
device-name(config)#qos remark <priority> {txq0|txq1|txq2|txq3|txq4|txq5|txq6|txq7}
Argument Description
priority The 802.1p priority level in range <0-7>.
txq0
Transmit queue 0.
txq1 Transmit queue 1.
txq2 Transmit queue 2.
txq3 Transmit queue 3.
txq4
Transmit queue 4.
txq5 Transmit queue 5.
txq6 Transmit queue 6.
txq7 Transmit queue 7.
Example
In the following example, the qos remark command re-marks the 802.1p priority levels for
txq1 and tx2 to priority 3 and priority 5 respectively. The show qos priority-txq-map
remark command prior to the configuration shows the default re-marking levels. Following
the configuration, the show command displays the changes.
