Converting an Alcatel OmniAccess Wireless System from Layer 2 to Layer 3 Mode

•
Using the ACS Web Interface
Using the Alcatel OmniAccess Switch or Appliance Web Browser
When you wish to convert an Alcatel OmniAccess Wireless System from Layer 2 to Layer 3 LWAPP
Transport Mode using the Alcatel OmniAccess Switch Web Interface, complete the following steps:
CAUTION:
until the Alcatel OmniAccess Switch or Appliance reboots and the associated Omni-
Access AP Access Points reassociate with the Alcatel OmniAccess Switch or
Appliance.
Layer 3 Mode requires that all subnets that the Alcatel OmniAccess Switches
Note:
or Appliances are connected to include at least one DHCP server. When you have
completed this procedure, the Alcatel OmniAccess Switch or Appliance stores its IP
address in its associated OmniAccess AP Access Points. When each OmniAccess AP
1200 or 1250 is powered up, it obtains an IP address from the local DHCP server,
and connects to its Primary Alcatel OmniAccess Switch or Appliance IP address.
Layer 3 Mode requires that all subnets that contain Alcatel OmniAccess WLAN
Note:
Switches, Alcatel OmniAccess WLAN Appliances and OmniAccess AP Access Points
are routable to each other.
1.
To use the Alcatel OmniAccess Wireless System in Layer 3 mode, you must create an
AP Manager Interface, which manages communications between each Alcatel OmniAccess
Switch or Appliance and its associated OmniAccess AP Access Points. This AP Manager Interface
will require a fixed IP address, which must be different from the Management Interface IP
address, but which can be on the same subnet as the Management Interface.
2.
MAKE SURE that all the Alcatel OmniAccess WLAN Switches, Alcatel OmniAccess WLAN Appli-
ances, and OmniAccess AP Access Points are on the same subnet: that they are only connected
through Layer 2 devices. If possible, connect the OmniAccess AP Access Points directly (or
through Layer 2 devices) to the front-panel 10/100Base-T ports on any 4012 or 4024 Alcatel
OmniAccess WLAN Switch.
CAUTION:
Switches or Appliances and associated OmniAccess AP Access Points to operate in
Layer 3 mode BEFORE completing the conversion.
3.
Verify that the OmniAccess AP Access Points are assigned to the desired Alcatel OmniAccess
Switch or Appliance. If you do not complete this step, the OmniAccess AP Access Points will fail
to associate with the Alcatel OmniAccess Switch or Appliance after completing the conversion.
