set port txq
16-8 Port Priority Configuration
Example
This example shows how to display the current algorithm and transmit queue weights configured
on port ge.1.1:
C3(su)->show port txq ge.1.1
Port Alg Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7
----- --- --- --- --- --- --- --- --- ---
ge.1.1 WRR 2 10 15 20 24 29 SP SP
set port txq
Use this command to set QoS transmit queue arbitration values for queues 0 through 5 on physical
ports. Queues can be configured for Weighted Round Robin (WRR) or strict priority (SP) or a
combination of both.
Syntax
set port txq port-string value0 value1 value2 value3 value4 value5
Parameters
Defaults
None.
Mode
Switch command, read-write.
Usage
Queues 0 through 5 can be set for strict priority (SP) or weighted round-robin (WRR), or a
combination of both. Queues 6 and 7 are reserved for stacking and control protocols and cannot
be modified by this command.
When configured for WRR, weights must total 100 percent. Strict priority may be assigned to all
queues by setting value5 to 100 percent. When combining SP and WRR, the values of those ports
running in WRR must total 100 percent.
You can mix WRR and SP by assigning SP to the higher numbered queues and assigning WRR to
the lower numbered queues, making sure that the values assigned to the WRR queues totals 100
port-string Specifies port(s) on which to set queue arbitration values. For a detailed
description of possible port-string values, refer to “Port String Syntax Used
in the CLI” on page 11-1.
Only physical ports can be configured with this command. LAG ports
cannot be configured.
value0 - value5 Specifies percentage to allocate to a specific transmit queue (WRR), or SP
for strict priority.
The values assigned to non-strict queues must total 100 percent.
Strict priority cannot be assigned to a queue if a higher queue is not strict.
Strict priority can be set on all five queues by setting the value for queue 5
to 100 percent.
