2. Specify a valid IP address on this Wireless Edge Services zl Module. You
have two options:
• Select Use Default Management Interface to use the address on the
management VLAN.
• Select Use this Local Address and manually enter an IP address.
3. Optionally, change the value in the Roam Interval field.
4. A station that roams at Layer 3 must maintain its association with its HM.
The roam interval specifies how long the Wireless Edge Services zl Module
stores a station’s association after it loses contact with the station—giving
the station’s traffic time to tunnel back to it after a Layer 3 roam.
The roam interval is added to the station timeout for the WLAN in
question. If you have set this value low and if your Ethernet network is
somewhat congested, you might need to increase the roam interval.
You can set the interval from between 1 and 300 seconds. The default
setting is 5 seconds.
