[c-nsp] What does "Tx-Bytes-Queue-X" mean in "show interface Gix/x counter details" output?

[Martin T]

Harold,
there is no Class-of-Service configuration associated with this
interface. Switch port configuration is very simple:

interface GigabitEthernet6/1
 description TEST
 switchport access vlan 9
 switchport mode access
 spanning-tree portfast
end

The main reason I ask for those "Tx-Bytes-Queue-[1-4]" queues/buffers
is that I have fluctuating packet delay variation(but no packet loss!)
to the server connected to this particular port and I was wondering
maybe those queues have something to do with this..


regards,
martin
