6 Availability, mobility, and controller
functionality
This chapter describes the availability and mobility concepts, including:
● Availability overview
● Mobility manager
● Defining management users
● Configuring network time
● Configuring Check Point event logging
● Enabling SNMP
● Using controller utilities
● Configuring Web session timeouts
The Summit WM series switch provides additional functionality including:
● Availability – Maintains service availability in the event of a Summit WM series switch outage
● Mobility – Allows multiple Summit WM series switches on a network discover each other and
exchange information about a client session. A maximum of up to 8 controllers can be linked to
allow users to transparently roam across controllers in the mobility domain.
Availability overview
The Summit WM series switch, access points, and WLAN switch software system provides this feature
to maintain service availability in the event of a Summit WM series switch outage.
The availability feature links two Summit WM series switches as a pair, to share information about their
Altitude APs. If one controller fails, its Altitude APs are allowed to connect to the backup controller.
The second Summit WM series switch provides the wireless network and a pre-assigned WM Access
Domain Service (WM-AD) for the Altitude AP.
NOTE
The Summit WM series switch's mobility domain licence (MDL) limits the number of APs that are allowed to
connect to the controller. During a failover event, the maximum number of failover APs a backup controller can
accommodate is equal to the number of MDLs that are purchased for that system.
NOTE
Altitude APs that attempt to connect to a backup controller during a failover event are assigned to the WM-AD that
is defined in the system’s default AP configuration. If a system default AP configuration does not exist for the
controller, the failover AP will not be assigned to any WM-AD.
Also, the default AP configuration assignment is only applicable to new APs that failover to the backup controller.
Any AP that has previously failed-over and is already known to the backup system will receive the configuration
already present on that system.
