AAA accounting reports and SNMP notifications
6 To enable the switch to be managed by 3WXM, select Managed. Until
this option is selected, you cannot deploy the switch configuration you
create in 3WXM to the actual switch in the network.
This option also enables the Launch Telnet and Launch Browser options in
the Task List panel.
After you select Managed to enable management of the switch by
3WXM, do not change this option unless advised to do so by 3Com
Technical Support. If you change a WX switch to an unmanaged state in a
network plan, all network operations (polling) stop for that WX switch. If
you change back to a managed state, the entire configuration of the
switch is replaced with the settings from the network plan, which can
result in loss of connectivity to the switch.
7 To modify the management interface, select the IP interface and VLAN
from the VLAN/IP drop-down list.
8 To modify the enable password, edit the string in the Enable Password
box.
Use this option when you are creating a new switch in 3WXM. This
option modifies the password in the network plan. However, if the switch
is already deployed in the network, 3WXM cannot apply configuration
changes to the switch unless the enable password in 3WXM matches the
enable password already configured on the switch.
9 To change the switch's Mobility Domain membership, select the Mobility
Domain from the Mobility Domain drop-down list.
To leave the switch out of all Mobility Domains, select Not Assigned.
10 To change the switch's wiring closet membership, select the closet from
the Wiring Closet drop-down list.
To leave the switch out of all wiring closets, select Not Assigned.
11 Click Save.
