ExtremeWare XOS 11.5 Command Reference Guide
387
show ports collisions
show ports {mgmt | <port_list>} collisions {no-refresh}
Description
Displays real-time collision statistics.
Syntax Description
Default
Real-time statistics.
Usage Guidelines
If you do not specify a port number or range of ports, collision statistics are displayed for all ports. To
clear the counters, use the
clear counters ports
command. The default display is a constantly refreshing
real-time display. If you specify the
no-refresh
parameter, the system displays a snapshot of the data
at the time you issue the command.
This status information may be useful for your technical support representative if you have a network
problem.
Example
The following command displays real-time collision statistics on slot 1, ports 1 and 2 on a modular
switch:
show ports 1:1-2 collisions
Following is sample output from this command:
