Chapter 8 Configuring Multiple SSIDs
When a client associates and the RADIUS server determines that it is unhealthy,
the server returns one of the quarantine NAC VLANs in its RADIUS
authentication response for
dot1x authentication. This VLAN must be one of
the configured back-up VLANs under the client SSID. If the VLAN is not one of
the configured back-up VLANs, the client is disassociated.
Data corresponding to the all the back-up VLANs are sent and received by using
the BSSID that is assigned to the SSID. Therefore, all clients (healthy and
unhealthy) listening to the BSSID corresponding the SSID wake up. Based on
the multicast key being used corresponding to the VLAN (healthy or unhealthy),
packet decrypting takes place on the client. Wired side traffic is segregated
because different VLANs are used, thereby ensuring that traffic from infected
and uninfected clients don’t mix.
A new keyword,
backup, is added to the existing vlan <name> | <id>
under dot11 ssid <ssid>
as described below:
vlan <name>|<id> [backup <name>|<id>, <name>|<id>,
<name>|<id>
