Cluster Recovery
In cases where the access points in a cluster become out of sync or an
access point cannot join or be removed from a cluster, the following
methods for cluster recovery are recommended.
Reboot or Reset
the Access Point
Stop Clustering
and Reset Each
Access Point in
the Cluster
These recovery methods are given in the order you should try them. In all
but the last case (stop clustering), you only need to reset or reboot the
particular access point whose configuration is out of sync with other cluster
members or cannot remove/join the cluster.
ˆ
Reboot the access point from its web UI. To do this, go to http://
IPAddressOfAccessPoint, navigate to Advanced > Reboot and click
Reboot. (IP addresses for access points are on the Cluster > Access
Points page for cluster members.)
ˆ
Physically reboot the access point by pressing the Reset button on the
AT-WA7400 Wireless Access Point.
ˆ
Reset the access point from its web UI. To do this, go to http://
IPAddressOfAccessPoint, navigate to Advanced > Reset
Configuration, and click Reset. (IP addresses for access points are
on the Cluster > Access Points page for any cluster member.)
ˆ
Physically reset the access point by pressing the Reset button on the
device.
ˆ
In some extreme cases, reboot or reset may not solve the problem. In
these cases, follow the procedure described next in “Stop Clustering
and Reset Each Access Point in the Cluster” to recover every access
point on the subnet.
If the previous reboot or reset methods do not solve the problem, do the
following to stop clustering and reset all access points:
1. Enter the Stop Clustering command as part of the URL in the address
bar of your web browser as follows:
http://IPAddressOfAccessPoint/stop_clustering.cgi
Where IPAddres0sOfAccessPoint is the IP address of the access
point you want to stop clustering. You can find the IP addresses for the
cluster members on the Cluster > Access Points page for any of the
clustered access points. Allied Telesyn recommends making a note of
all IP addresses at this point.
