View the SLP activity with the “slpdump tool”
1 In the Altitude AP Registration Mode screen, click on the View SLP Registration button. A popup
screen displays the results of the diagnostic “slpdump tool”, to confirm SLP registration.
In normal operations, the primary Summit WM-Series Switch registers as an SLP service called
“ac_manager” and directs the Altitude APs to the appropriate Summit WM-Series Switch of a pair.
During an outage, if the remaining Summit WM-Series Switch is the secondary one, it will register as
an SLP service “ru_manager”.
Events and actions during a Failover
If one of the Summit WM-Series Switches in a pair fails, the connection between the two Summit WM-
Series Switches is lost. This triggers a “Failover mode” condition, and a critical message appears in the
information log of the remaining Summit WM-Series Switch.
After the Altitude AP on the failed Summit WM-Series Switch loses its connection, it will attempt a
reboot. Because of the pairing of the two Summit WM-Series Switches, the Altitude AP will then
register with the other Summit WM-Series Switch.
NOTE
A Altitude AP connects first to a Summit WM-Series Switch registered as “ac_manager” and, if not found, then
seeks an “ru_manager”. If the primary Summit WM-Series Switch fails, the secondary one registers as
“ru_manager”. This enables the secondary Summit WM-Series Switch to be found by Altitude APs after they reboot.
When the Altitude APs connect to the second Summit WM-Series Switch, they will be assigned to the
Failover WM-AD defined in setup in that Summit WM-Series Switch. The wireless device users will log
in again and be authenticated on the second Summit WM-Series Switch.
When the failed Summit WM-Series Switch recovers, each Summit WM-Series Switch in the pair goes
back to normal mode. They exchange information that includes the latest lists of registered Altitude
APs. The administrator will release the Altitude APs on the second Summit WM-Series Switch, so that
they may re-register with their home Summit WM-Series Switch.
