Fast Layer 2 Roaming and Layer 3 Mobility
Verifying and Managing Layer 3 Mobility
Viewing a Station’s Status
A successful Layer 3 roam should meet these criteria:
■ The station roams seamlessly at Layer 2—that is, the station reassociates
and re-authenticates in the background.
■ The station maintains its IP address.
■ The Wireless Edge Services zl Module that supports the station’s new RP
becomes the station’s CM and tunnels traffic back to the station’s HM.
To test Layer 3 roaming, move a station from one RP’s cell to the cell of an RP
supported by a different Wireless Edge Services zl Module. Verify that the
station’s IP address remains the same and sessions remain active.
You can also verify a Layer 3 roam from your module’s Web browser interface.
To view information about stations, select Network Setup > Layer 3 Mobility and
click the Station Status tab. You can also view this information by selecting
Device Information > Wireless Stations and clicking the Layer 3 Mobility-Station
Status tab.
