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.
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:

This command was first available in ExtremeXOS 11.3.
The tag value was added in ExtremeXOS 12.4.4.
This command is available on ExtremeSwitching 5320, 5420, 5520, and 5720 series switches. The stack-ports option is available only on SummitStack.
