Port Priority and Rate Limiting Configuration Command Set
Configuring Priority to Transmit Queue Mapping
8-8 SecureStack A2 Configuration Guide
8.3.2.2 set port priority-queue
Use this command to map 802.1D (802.1p) priorities to transmit queues. This command enables
you to change the transmit queue (0 through 5, with 0 being the lowest priority queue) for each port
priority of the selected port. You can apply the new settings to one or more ports.
set port priority-queue port-string priority queue
Syntax Description
Command Defaults
None.
Command Mode
Read-Write.
Example
This example shows how to set priority 5 frames received on fe.2.12 to transmit on queue 0.
NOTES: Priority to transmit queue mapping on an individual port basis can only be configured on
Gigabit Ethernet ports (ge.x.x). When you use the set port priority-queue command to configure
a Fast Ethernet port (fe.x.x), the mapping values are applied globally to all Fast Ethernet ports on
the stack.
Although there are eight queues implemented in the switch hardware, only six are available for
use in prioritizing various data and control traffic. The 7th and 8th queues are reserved for
stacking and network control-related communications. Refer to Section 8.3.3 for more information
about configuring the priority mode and weight for these queues.
port-string Specifies the port(s) for which to set priority-to-queue
mappings. For a detailed description of possible
port-string values, refer to Section 3.1.1.
priority Specifies a value of 0 – 7 (0 is the lowest level) that
determines what priority frames will be transmitted on the
transmit queue entered in this command.
queue Specifies a value of 0 through 5 (0 is the lowest level) that
determines the queue on which to transmit the frames with
the port priority entered in this command.
