Configuring Layer 3 Mobility
You must complete these tasks to configure Layer 3 mobility:
1. Configure Layer 3 mobility settings for the local Wireless Edge Services
xl Module:
IP address
WLANs on which Layer 3 mobility is enabled
2. Specify the peers’ IP addresses.
3. Enable Layer 3 mobility.
4. Save the configuration and complete these steps on all other Wireless
Edge Services xl Modules in the Layer 3 mobility domain.
It is assumed that you have completed the configurations outlined in Table 9-2.
Note You cannot use user-based, or dynamic, VLANs in a WLAN assigned to the
Layer 3 mobility domain. In other words, the Dynamic Assignment box in the
WLAN’s Edit screen must be unchecked.

Configuration Necessary Settings
WLAN configuration (for each WLAN
on which Layer 3 mobility is enabled)
SSID and security settings are the same as peers’
settings.
VLAN ID is different from at least some peers’
VLAN settings. (Different subnetworks
must have
different VLAN IDs.)
Dynamic VLAN assignment is disabled.
IP configuration on the local module The module can reach peers.
The peers can reach the module.
IP configuration for stations DHCP is provided through either:
local DHCP pool for the VLAN mapped to the
WLAN
external DHCP server
Static IP addresses, if used, are manually
configured (not typical).
