TitleHow to check ports utilization on Exos switches.
Objective
How to check ports utilization on Exos switches? 
Environment
  • All Exos Switches
  • All Exos version
Procedure
  • Use the command "show ports {mgmt | port_list | tag tag | stack-ports stacking-port_list}
    utilization {bandwidth | bytes | packet}" 
    • 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.
  • ​Find below example for the output of port 1 and 4 utilization. 
Switch.1 # show ports 1, 4 utilization

  • 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.
