Fast Layer 2 Roaming and Layer 3 Mobility
Verifying and Managing Layer 3 Mobility
The screen displays the following information for every station associated
with any Wireless Edge Services xl Module in the Layer 3 mobility domain:
■ Station MAC—station MAC address
■ Station IP—station IP address
■ Home Module IP—HM IP address
■ Home Module VLAN—HM VLAN ID
■ Curr Module IP—CM IP address
■ Roam—This column tracks Layer 3 roams. The station is considered to be
in a roaming state (green check mark) if its CM differs from its HM.
In Figure 9-12, the 10.4.1.30 Wireless Edge Services xl Module is the HM for
three stations associated with the wireless network, and the 10.4.2.30 module
is the HM for one station. However, one of the 10.4.1.30 module’s stations has
roamed to an RP supported by the 10.4.2.30 module. Because these two
modules are on different VLANs, the roam occurred at Layer 3. As you can see
in the top row in Figure 9-12, the station has 10.4.1.30 as its HM, but 10.4.2.30
as its CM; the Roam column has a green check mark.
