The Brocade Silkworm family of switches maintain a number of important performance and reliability counters for each switch port. Performance and reliability counters for specific switch ports can be viewed with the porterrshow, portshow and portStatsShow commands. To view system wide throughput statistics, the portPerfShow command can be run with an optional interval:
switch1:admin> **portPerfShow 5**

The individual switch ports are listed above the dashes, and the numbers below the dashes contain the number of bytes transmitted and received per second. This is a super useful tool for getting a high level overview of what your switch is doing.
