D-Link DWS-1008 User Manual
To monitor port statistics beginning with octet statistics (the default), type the following command:
DWS-1008#
monitor port counters
As soon as you press Enter, MSS clears the window and displays statistics at the top of the window. In
this example, the octet statistics are displayed first.

To cycle the display to the next set of statistics, press the Spacebar. In this example, packet statistics
are displayed next:

Configuring Load-Sharing Port Groups
A port group is a set of physical ports that function together as a single link and provide load sharing
and link redundancy. Only network ports can participate in a port group.
You can configure up to 6 ports in a port group, in any combination of ports. The port numbers do not
need to be contiguous and you can use 10/100 Ethernet ports and gigabit Ethernet ports in the same
port group.
Load Sharing
A switch balances the port group traffic among the group’s physical ports by assigning traffic flows to
ports based on the traffic’s source and destination MAC addresses. The switch assigns a traffic flow to
an individual port and uses the same port for all subsequent traffic for that flow.
Link Redundancy
A port group ensures link stability by providing redundant connections for the same link. If an individual
port in a group fails, the switch reassigns traffic to the remaining ports. When the failed port starts
operating again, the switch begins using it for new traffic flows. Traffic that belonged to the port before it
failed continues to be assigned to other ports.
