NETGEAR 8800 Chassis Switch CLI Manual Description Displays egress packet counts or dropped-traffic counts for each QoS profile on the specified ports. Syntax Description port_list congestion no-refresh Specifies one or more slots and ports. Specifies the display of packets dropped at ingress due to port congestion. Specifies a static snapshot of data instead of the default dynamic display. Default Displays egress packet counts in real-time. Usage Guidelines The bottom line in the real-time display shows keys that you can press to change the display. For example, the spacebar toggles the display between egress packet counts and ingress dropped-packet counts. Note: This command does not work properly if another CLI session is displaying congestion statistics in real time. If you specify the no-refresh parameter, the system displays a snapshot of the data at the time you issue the command. Note: Packets can be dropped at multiple locations along the path through the hardware. Due to hardware limitations, the dropped-packet counters for QoS profiles cannot count dropped packets from all possible locations. Because of these limitations, the sum of all dropped packets for all QoS profiles can be less than the per port count displayed with the command: show ports congestion {no-refresh}. You can display packet counts for one port per slot or module at a time. You can simultaneously display packet counts for multiple ports, but they must be from different slots or modules. The dropped packet display is limited to the 8 most-significant digits. When you display the packet counts for a port, this action configures the hardware to monitor that port. If the slot or module hardware was previously configured to monitor a different port, Chapter 14. QoS Commands | 549
