Interface Overview

Fibre Channel Port Rate Limiting

Fibre Channel Port Rate Limiting
The Fibre Channel port rate-limiting feature for the Cisco MDS 9100 Series controls the amount of bandwidth
available to individual Fibre Channel ports within groups of four host-optimized ports. Limiting bandwidth
on one or more Fibre Channel ports allows the other ports in the group to receive a greater share of the available
bandwidth under high-utilization conditions. Port rate limiting is also beneficial for throttling WAN traffic at
the source to help eliminate excessive buffering in Fibre Channel and IP data network devices.
