ExtremeWare 7.5 Command Reference Guide 325
show ports collisions
show ports {mgmt | <portlist>} collisions
Description
Displays real-time collision statistics.
Syntax Description
Default
N/A
Usage Guidelines
If you do not specify a port number or range of ports, collision statistics are displayed for all ports.
On a modular switch,
<portlist>
can be a list of slots and ports. On a stand-alone switch,
<portlist>
can be one or more port numbers. For a detailed explanation of port specification, see “Modular Switch
Numerical Ranges” or “Stand-alone Switch Numerical Ranges” in Chapter 1.
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 port 7 on a stand-alone switch:
show ports 7 collisions
The following command displays real-time collision statistics on slot 1, ports 1-16 on a modular switch:
show ports 1:1-1:16 collisions
Following is the output from this command:

mgmt Specifies the management port. Supported only for switches that provide a management port.
portlist Specifies one or more ports or slots and ports. On a modular switch, can be a list of slots and ports.
On a stand-alone switch, can be one or more port numbers. May be in the form 1, 2, 3-5, 2:*, 2:5,
2:6-2:8.
