If you select Web Portal in step 2, 3WXM automatically creates a user
named web-portal-wired. Similarly, if you select Open Access, 3WXM
creates a user called last-resort-wired. Do not delete or modify these
users.
(You can add, modify, or delete users at any time, even after this wizard
is closed. See “Creating and Managing Users in the Local User Database”
on page 289.)

Viewing and
Changing 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.
The WX balances port group traffic among the group’s physical ports by
assigning traffic flows to ports based on the source and destination MAC
addresses of the traffic. The WX assigns a traffic flow to an individual port
in the group and uses the same port for all subsequent traffic for that flow.
A port group ensures link stability by providing redundant connections for
the same link. If an individual port in a group fails, the WX reassigns
traffic to the remaining ports. When the failed port starts operating
again, the WX begins using it for new traffic flows. Traffic that belonged
to the port before it failed continues to be assigned to other ports.
Layer 2 configuration changes apply collectively to a port group as a
whole but not to individual ports within the group. For example,
Spanning Tree Protocol (STP) changes affect the entire port group rather
than 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 and not to port groups.
Viewing Port Groups To view port groups:
1 Select the Configuration tool bar option.
2 In the Organizer panel, click the plus sign next to the WX switch.
3 Click the plus sign next to System.

The configured port groups and their member ports appear in the
