Chapter 21 Troubleshooting
NWA3000-N Series User’s Guide
273
If a RADIUS server authenticates wireless stations, the re-authentication timer on
the RADIUS server has priority. Change the RADIUS server’s configuration if you
need to use a different re-authentication timer setting.
Device HA is not working.
• You may need to disable STP (Spanning Tree Protocol).
• The master and its backups must all use the same device HA mode (active-
passive).
• Configure a static IP address for each interface that you will have device HA
monitor.
• Configure a separate management IP address for each interface. You can use it
to access the NWA3000-N series AP for management whether the NWA3000-N
series AP is the master or a backup. The management IP address should be in
the same subnet as the interface IP address.
• Enable monitoring for the same interfaces on the master and backup NWA3000-
N series APs.
• Each monitored interface must have a static IP address and be connected to the
same subnet as the corresponding interface on the backup or master NWA3000-
N series AP.
• If you have multiple NWA3000-N series AP virtual routers on your network, use
a different cluster ID to identify each virtual router. There can only be one
master NWA3000-N series AP in each virtual router (same cluster ID).
A broadcast storm results when I turn on Device HA.
Do not connect the bridge interfaces on two NWA3000-N series APs without device
HA activated on both. Either activate device HA before connecting the bridge
interfaces or disable the bridge interfaces, connect the bridge interfaces, activate
device HA, and finally reactivate the bridge interfaces.
I cannot get the Device HA synchronization to work.
Only NWA3000-N series APs of the same model and firmware version can
synchronize.
