Managing Access Radio SSIDs
Managing Access Radio SSIDs
Each access radio supports up to 16 SSIDs. If associated clients use different
SSIDs, then the BelAir100 can use the SSID to direct traffic to different VLANs.
You can also enable a Basic SSID (BSSID) for up to eight SSIDs. The BSSID has
the same format at a MAC address. By enabling a BSSID, you are effectively
creating a virtual AP for the associated clients that use that SSID.
Note: To maximize multipoint-to-multipoint mesh performance, BelAir
Networks recommends that you do not enable BSSIDs on BelAir50C
and BelAir50S platforms.
To manage client association, the access radio periodically emits a beacon
dataframe. The following SSID types are available, based on their effect on the
beacon dataframe:
• A public SSID means that the SSID information element is present in the
beacon dataframe, has a length and a value.
• A private SSID means that there is no beacon dataframe. Instead, the
association is managed through a client’s probe and response dataframe
session.
SSID 1 is usually a public SSID, but its behavior can be configured. All other
SSIDs are always private. SSID 1 also always has an enabled BSSID.
Finally, you can use the commands described in this chapter to map an SSID to
a VLAN.
Adding or
Modifying an SSID
set arm<n> ssid <ssid_string>
[ssidx <ssid_index>] [vlan <vlan_ID>]
set arm<n> ssid <ssid_string> {normal|suppress|broadcast}
[ssidx <ssid_index>] [vlan <vlan_ID>]
These commands add or modify the access radio SSID with the given index
number.
The
ssid_string
parameter is the SSID setting. SSIDs are case sensitive and can
contain up to 32 alphanumeric characters.
The
ssid_index
parameter is an integer from 1 to 16. The default value is 1.
The
vlan_id
parameter, if present, specifies that traffic for all wireless clients
associated to the BelAir100 unit with the given SSID be directed to the
specified VLAN. The VLAN ID is an integer from 1 to 2815. If no VLAN is
specified, traffic from the wireless clients corresponding to that SSID is passed
through the access radio without change.
