The WLAN Configuration page contains three sub-menu pages:
ESSID definition
Radios
Assignments
Configuring ESSIDs
An ESSID (Extended Service Set Identifier) is the name of the network. Wireless devices must
connect to a specific ESSID which determines the pre-defined set of privileges, settings, and
limitations (such as security definitions, access privileges, VLAN assignments, etc.) of the network.
Each channel can support multiple ESSIDs, thus creating “virtual” networks on the same channel.
The following is the data structure used by the Extricom system:
Each radio is assigned one channel.
Each channel can support up to 8-16 different ESSIDs (see note below).
Each ESSID can be associated with a VLAN tag.
The same ESSID name can be repeated for different channels;
On the EXSW-1200, EXSW-2400, and Multi Series 1000, up to 7 ESSIDs are
allowed on channel 1, and up to 8 ESSIDs are allowed on each of the remaining
channels.
On the EXSW-400 and EXSW-800, up to 15 ESSIDs are allowed on channel 1, and
up to 16 ESSIDs are allowed on channel 2.
There is a maximum of 31 ESSIDs per system.
Table 8 below shows an example of possible channel, ESSID and VLAN tag assignments for the
EXSW-400 and EXSW-800 switches.
