show qos cosq-stats

Display the Quality of Service (QoS) egress queues statistics. The show output displays either unicast packet stats for each port, or all stats, based on your hardware platform.

Syntax

Command Parameters

interface {slot/port[/sub-port][-slot/port[/sub-port]][,...]}
Show Qos Cosq Stats on port. {slot/port[/sub-port][-slot/port[/sub-port]][,...]} identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If your platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
loopback-port <1-2>
Shows Qos Cosq Stats on loopback port.

Default

None

Usage Guidelines

The show command output varies based on your hardware platform. On all supported platforms except the VSP 8600 Series, the show command output displays Out Packets and Out Bytes per interface, which shows the number of unicast packets sent out on each queue for an egress port. VSP 8600 Series uses VoQ queuing architecture, which enables to read the Accepted Packets and Accepted Bytes on each queue. The Accepted Packets and Accepted Bytes show the number of packets and bytes that enter the VoQ for a particular queue on the egress port. The Drop Packets and Drop Bytes show the number of packets and bytes that are dropped when the VoQ is full.

Command Output

The show qos cosq-stats command displays the following information:
