ethernet summary
Displays a summary of Ethernet port information. The summary shows
the port’s label and status, as well as the most pertinent statistics about
general port activity and port errors.

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.
