show ports utilization

show ports {mgmt | port_list | tag tag | stack-ports stacking-port_list} utilization {bandwidth | bytes | packet}

Description

Displays real-time port utilization information. The total utilization displays as real-time information, constantly refreshing. and the parameter displays show a snapshot of the activity on the port when you issue the command.

Syntax Description

mgmt

Specifies the management port.

port_list

Specifies one or more ports or slots and ports.

tag

Specifies an 802.1Q or 802.1ad tag value.

stacking-port_list

Specifies one or more stacking slots and ports.

bandwidth

Specifies port utilization as percentage of bandwidth.

bytes

Specifies port utilization in bytes per second.

packet

Specifies port utilization in packets per second.

Default

N/A.

Usage Guidelines

The software continuously monitors port utilization and calculates bandwidth as a function of each port‘s maximum link capacity.

The total utilization display presents real-time statistics. Use the spacebar to toggle the real-time displayed information for packets, bytes, and bandwidth in that order. When you use a parameter (packets, bytes, or bandwidth) with the command, the display for the specified type shows a snapshot per port when you issued the command. When the show ports utilization command is run with the bandwidth, bytes, or packets options, the command may need to be repeated a few times in order for the ExtremeXOS software to gather enough statistics to calculate appropriate values.

If you do not specify a port number, range of ports, or tag value, port utilization information is displayed for all ports.

The tag value may be associated with either a VMAN or a VLAN.

This status information may be useful for your technical support representative if you have a network problem.

Example

The following command displays utilization statistics for port 1 on a stand-alone switch:

show ports 1 utilization

The following command displays utilization statistics for slot 3, port 1 on a modular switch:

show ports 3:1 utilization

The following example shows sample output from the show ports utilization packets command:
