fe.2.5 is set to 0
set port priority
Use this command to set the 802.1D (802.1p) Class ‐ of ‐ Service transmit queue priority (0 through 7)
on each port.
Syntax
set port priority port-string priority
Parameters
Defaults
None.
Mode
Switch command, Read ‐ Write.
Usage
For information on how to configure protocol ‐ based policy classification to a Class ‐ of ‐ Service,
including how to configure a CoS policy to override port transmit queue priority, refer to
Chapter 8 .
When CoS override is enabled using the set policy profile command as described in “ set policy
profile ” on page 8 ‐ 3, CoS ‐ based classification rules will take precedence over priority settings
configured with this command.
A port receiving a frame without priority information in its tag header is assigned a priority
according to the priority setting on the port. For example, if the priority of a port is set to 5, the
frames received through that port without a priority indicated in their tag header are classified as
a priority 5. A frame with priority information in its tag header is transmitted according to that
priority.
Example
This example shows how to set a default priority of 6 on fe.1.3. Frames received by this port
without priority information in their frame header are set to the default setting of 6:
Matrix(rw)->set port priority fe.1.3 6
clear port priority
Use this command to reset the current CoS port priority setting to 0.
Syntax

possible port ‐ string values, refer to “ Port String Syntax Used in the CLI ”
