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 8 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 WX 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 WX switch 
reassigns traffic to the remaining ports. When the failed port starts 
operating again, the WX switch begins using it for new traffic flows. 
Traffic that belonged to the port before it failed continues to be assigned 
to other ports.
Configuring a Port Group
To configure a port group, use the following command:
set port-group name group-name port-list mode {on | off}
Enter a name for the group and the ports contained in the group. 
Do not use dashes or hyphens in a port group name. MSS will not display 
or save the port group. The port group name must start with a letter.
The mode parameter adds or removes ports for a group that is already 
configured. To modify a group:
„
Adding ports — Enter the ports you want to add, then enter mode 
on
.
„
Removing ports — Enter the ports you want to remove, then enter 
mode off.
