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.
|
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. |
N/A.
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 (Virtual LAN).
This status information may be useful for your technical support representative if you have a network problem.
The following command displays utilization statistics for port 1 on a stand-alone switch:
show ports 1 utilization
The following example shows sample output from the show ports utilization packets command:

Note
Use the spacebar to toggle this real-time display for all ports from packets to bytes to bandwidth, in that order.
The following example shows sample output from the show ports utilization bytes command:

The following example shows sample output of the show ports utilization bandwidth command:

This command was first available in ExtremeXOS 11.3.
The tag value was added in ExtremeXOS 12.4.4.
This command is available on the Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X590, X620, X690, X870 series switches. The stack-ports option is available only on SummitStack.
