Monitoring Forwarding and Drop Rates on the Egress Queue

Display information about forwarding and drop rates on the egress queue. The show
Purpose
egress-queue rates command is useful even if no statistics profiles are configured.
You can view information about all of the queues even if statistics gathering has not
been enabled.
The minimum rate for the queue is the minimum rate at which a node or queue can
transmit when all other nodes and queues compete for bandwidth. The system
determines the minimum rates by the weight and assured rate configured in a
scheduler profile, and are subject to shaping rate and shared-shaping rate configured.
The maximum rate is the maximum rate at which a node or queue can transmit
when there are no other nodes or queues competing for bandwidth. The system
calculates the maximum rate as the minimum of all shaping rates, shared-shaping
rates, and the port rate from the node or queue down to the port.
For example, if a scheduler column configured over a Fast Ethernet port consists of
a VLAN queue that has been shaped to 5 Mbps over a VLAN node that has been
shaped to 8 Mbps, over an S-VLAN node which is not shaped, then:
To display rate statistics only for queues that have queue rate statistics enabled:

To display rate statistics by color rather than as an aggregate of all colors:

---------------------- -------
The VLAN queue that is shared-shaped to 5 Mbps has a maximum rate of 5 Mbps.
The VLAN node that is shaped to 8 Mbps has a maximum rate of 8 Mbps.
The S-VLAN node which is not shaped has a maximum rate of 100 Mbps.
The Fast Ethernet port with a bandwidth of 100 Mbps has a maximum rate of
100 Mbps.
