Switch Management Commands 2236
Example
The following example shows a classical incast situation on interface Gi1/0/2
where the port is fully utilized or nearly fully utilized, buffering many frames
(with increased latency) and beginning to drop frames as the internal
thresholds for buffering on the port are reached. A conscientious network
operator might want to examine why the devices attached to Gi1/0/5 and
Gi1/0/6 are sending so much traffic to Gi1/0/2 attached devices and either re-
distribute the devices, rate-limit traffic egressing the devices attached to
Gi1/0/5 and Gi1/0/6, or increase the number of links available for the device
attached to Gi1/0/2.
