Egress port shaping
Egress port shaping limits the amount of aggregate traffic transmitted through a port.
To be effective, the egress port-shaping rate must be less than the port's line rate. By default, the egress port-shaping rate is the same as the line-rate of the port. Buffers associated with each port store excess traffic.
When both egress port-shaping and egress queue-shaping are configured on the same interface, the switch respects the minimum of both configurations.
