Important Considerations

■Port numbering is consecutive, regardless of module type (if you are using a system that has modules).

■Depending on the system, numbering may or may not skip an empty slot and continue with the ports that are associated with the next occupied slot. (See the Implementation Guide for your system for specific information about port numbering.)

■Numbering includes unused ports.

■Only one port number is assigned to a Gigabit Ethernet module in switches that use Gigabit Ethernet modules.

■The system no longer assigns port number 1 to the out-of-band management port, which does not receive a port number.

■The rxFrames value that the Ethernet summary command reports for a bridge port may differ from the value that the bridge port summary command reports. The Ethernet summary command counts all frames that are delivered to the port while the bridge port summary command reports only valid frames that are passed to the port. Therefore, the Ethernet summary value should exceed the bridge port summary value by the number of receive errors (rxErrs).

■At some prompts, you can specify the ? option to list Ethernet ports and port numbers. The ? option displays Selection, Port, and Port Label columns. The Selection column and Port column contain the same port numbers because they represent your physical ports.
