•If there are multiple WLAN Security Switch 2270s installed, which are intended to participate in a single RF mobility group, the following criteria must be met:
—The RF mobility group name must be same on all 2270s that belong to the RF mobility group.
The mobility group name is case sensitive.
—Configure the virtual IP address for virtual interface to a nonroutable address (for example, a fictitious address such as 1.1.1.1). The virtual IP address must be same on all 2270s that belong to the RF mobility group.
—Manually add each switch to the list of RF mobility group members for each switch.
This is not a dynamic configuration.
For example, you have three switches: A, B, and C.
