Fast Layer 2 Roaming and Layer 3 Mobility
Verifying and Managing Layer 3 Mobility
■ 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 9-13, the 10.4.1.30 Wireless Edge Services zl 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 9-13,
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.
