Hi Michael,

Thanks for writing it to the portal.

In order to check the queue status, the command "show interface etx counters queue detail" where x will be the particular interface can be used.

For example:-

show interface et1 counters queue detail
Port     TxQ   Counter/pkts      Counter/bytes      Drop/pkts         Drop/bytes
------- ----   ------------       ------------   ------------       ------------
Et1      UC0              0                  0              0                  0
Et1      UC1              0                  0              0                  0
Et1      UC2              0                  0              0                  0
Et1      UC3              0                  0              0                  0
Et1      UC4              0                  0              0                  0
Et1      UC5              0                  0              0                  0
Et1      UC6              0                  0              0                  0
Et1      UC7              0                  0              0                  0
Et1      UC8          80676           1734531   0                  0
Et1      MC0              0                  0              0                  0
Et1      MC1        1815093          1278447   0                  0
Et1      MC2              0                  0              0                  0
Et1      MC3              0                  0              0                  0
Et1      MC4              0                  0              0                  0
Et1      MC5              0                  0              0                  0
Et1      MC6           1759             112576      0                  0
Et1      MC7              3                204              0                 0

Hi Michael,

I believe that we can use the following commands to verify the queue status of all the individual interfaces.

#sh interfaces counters queue ?
detail Queue counters in detail
drops Queue drops counters
ingress Queue ingress counters
rates Queue counters rates

#sh interfaces counter queue rates is a good command which shows the configured bps values and the drop rates and the output in percentage values for each Tx queue, UC0-7 and MC0-7.

#sh interfaces counters queue rates
Et1 - load interval 5.0s
Offered load (include drop) Config Drop rates Output rates
bps pps % of % of bps SP/WRR bps pps bps pps % of % of WRR %
link total link total
----- ------ ------ ------ ------ ----- ------ ----- ----- ----- ----- ----- ----- -----
UC0 0.0 0.0 0.0% 0.0% N/A SP 0.0 0.0 0.0 0.0 0.0% 0.0% N/A
UC1 0.0 0.0 0.0% 0.0% N/A SP 0.0 0.0 0.0 0.0 0.0% 0.0% N/A
. . .

MC5 0.0 0.0 0.0% 0.0% N/A SP 0.0 0.0 0.0 0.0 0.0% 0.0% N/A
MC6 0.0 0.0 0.0% 0.0% N/A SP 0.0 0.0 0.0 0.0 0.0% 0.0% N/A
MC7 0.0 0.0 0.0% 0.0% N/A SP 0.0 0.0 0.0 0.0 0.0% 0.0% N/A
Total 0.0 0.0 0.0% 0.0% N/A 0.0 0.0 0.0 0.0 0.0% 0.0% N/A

In the above example, the values are 0.0% as I do not have any qos configs on the interface currently. If the qos is configured then the command output would reflect the same.

Let us know if this helps. If you have any further queries/concerns, please revert or feel free to raise a case with support@arista.com.
