Dell 6.2 Configuring Fa llback Mode

You definet hebackup configuration in the virtual AP profile on the controller. Theremote A P checks for
configuration updates eacht ime it establishes a connection with t hec ontroller.If the remote AP detects a change,
it downloads the configuration changes.
The followingremote A P backup configuration options define when the SSID is advertised (refer to Table 170 for
more information):
lAlways—Permanentlyenables the virtual AP. R ecommendedfor bridge SSIDs.
lBackup—Enablesthe virtual AP if the remote AP cannot connect to the controller.This SSID i s advertised until
the controlleris reachable.Recommended for bridge SSIDs.
lPersistent—Permanentlyenables the virtual AP after the remote AP initially connects to t heco ntroller.
Recommendedfor 8 02.1x SSIDs.
lStandard—Enablesthe virtual AP when the remote AP connects to the controller. Recommended for 802.1x,
tunneled,and split-tunneled SSIDs. This is the default behavior.
Whileusing the backup configuration, the remote AP periodically retries its IPSec tunnel to the controller. If you
configurethe remote AP in backupmode, and a connection to t heco ntrolleris re-established, the remote AP stops
using the backupconfiguration and immediately brings up the standard remoteA P configuration. If you configure
the remote AP in always or persistent mode, the backupco nfigurationremains active after the IPSec tunnel to the
controllerhas been re-established.
Backup Configuration Behavior for Wired Ports
If the connection between remote AP and the controlleris di sconnected,the remote AP will be exhibit the following
behavior:
lAll access ports on the remote AP, i rrespective of their original forwardingmode w illbe moved to bridge
forwardingmode.
lClients willreceive IP address fromthe remote AP's DHCP server.
lClient will have complete access to Remote A P's uplinknetwo rk.You cannot enforceor modify any access
control policies on the clients connected in this mode.
