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.
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.
To configure a port group named server1 containing ports 1 through 5
and enable the link, type the following command:
WX1200# set port-group name server1 1-5 mode on
success: change accepted.
After you configure a port group, you can use the port group name with
commands that change Layer 2 configuration parameters to apply
configuration changes to all ports in the port group. For example,
Spanning Tree Protocol (STP) and VLAN membership changes affect the
entire port group instead of individual ports. When you make Layer 2
configuration changes, you can use a port group name in place of the
port list. Ethernet port statistics continue to apply to individual ports, not
to port groups.
