The Summit WM-Series WLAN Switch Software solution's availability feature
maintains service availability in the event of a Summit WM Switch outage.
The availability feature links two Summit WM Switches to form a pair in order to
share information about their Altitude APs. If one Summit WM Switch fails, its
Altitude APs are allowed to connect to the other Summit WM Switch.
The Altitude APs that connect to a backup Summit WM Switch during a failover
are assigned to the WM-AD that is defined in the Summit WM Switch's default
Altitude AP configuration. If the default Altitude AP configuration does not exist
for the backup Summit WM Switch, the failover Altitude APs will not be assigned
to any WM-AD, and will therefore not provide service. Therefore it is very
important to define a default Altitude AP configuration on all Summit WM
Switches.
Before you begin the availability configuration, you must ensure:
•
A network connection exists between the two Summit WM Switches. This
connection is used to enable the availability link between the Summit WM
Switches. The availability link is established on port 13907.
•
A DHCP server for the Altitude AP subnets is setup to support "Option 78 for
SLP", so that it points to the IP addresses of the physical interfaces on both
the Summit WM Switches.
