Displaying QoS statistics
To display traffic statistics for each output queue on an interface, use the show interface <id> queue-detail command in running or candidate mode.
The following example displays output queue statistics for an interface on a 7250 IXR system. The output on a 7220 IXR-D2, D3, and D5 or 7220 IXR-H2 and H3 system is similar, but shows slightly different information.

Clearing QoS statistics
To reset the queue statistics counters for an interface, use the tools interface qos output queue-statistics clear command.
Reset all statistics counters on an interface
The following example resets all output queue statistics counters on an interface:
--{ running }--[ ]--
# tools interface ethernet-1/1 qos output queue-statistics clear
Reset statistics counters for multicast egress queue
The following example resets statistics counters for a specified egress queue (multicast) on an interface:
--{ running }--[ ]--
# tools interface ethernet-1/1 qos output queue-statistics queue multicast-queue-1 clear
QoS profile resource usage
A QoS profile resource refers to the number of classifier and rewrite policies that are applied to interfaces on a line card. Each classifier or rewrite policy that is applied to an interface on a line card counts as one profile resource used.
For example, if you create classifier policy dscp1 and apply it to input IPv4 traffic on an interface, and apply the same dscp1 policy to input IPv6 traffic on a different interface on the same line card, it counts as two classifier profile resources used.
The SR Linux supports up to 15 classifier profile resources and up to 32 rewrite profile resources per line card. You can display the number of QoS profile resources in use for each line card.
Displaying QoS profile resource usage on a 7250 IXR system
To display QoS profile resource usage on a 7250 IXR system, use the info from state command.
The following example displays the number of used and free classifier and rewrite profile resources for a line card:
# info from state platform linecard 1 forwarding-complex 0 qos
platform {
linecard 1 {
forwarding-complex 0 {
qos {
resource classifier-profiles {
used 1
free 15
resource rewrite-profiles {
used 1
free 31
}
}
}
}
}
