Wireless Access

hello Airheads,
can ayone help.
i have version MM/MD deployment and an extensive RAP deployment.
I am trying to find out the hearbeat interval for the RAPs as we have a lot of them bootstrapping.
We think it's the customer WAN.
I know on V6 it used to be 30seconds. (i can see 1 second but cant believe that's right)!!!
but cant find value in system profile.
cheers
pete

Access Points and Controllers exchange heartbeat messages as keepalive mechanism and the interval between each heartbeat is 1 second by default. You can configure the heartbeat interval. See below for the effect it may cause though:

By default heartbeat-interval for CAP's, RAP's 1 second.

Interval can be set anything between 1 to 60 seconds.

By default bootstrap threshold for CAP's is 8 seconds and for RAP's 30 seconds.

Increase in heartbeat interval shoots up the bootstrap time. This increases the time that an Access Point takes to detect a loss in connectivity to controller. Bootstrap time is calculated as shown below:
Bootstrap time = Heartbeat interval * Bootstrap threshold

For eg:
HB interval = 5 sec
Bootstrap Threshold = 8
Bootstrap time = 40


You can find the configured heartbeat interval by showing the AP system profile assigned to the AP-Group or individual AP if you have that set. See below for where it is:

(ARUBA-MC01) [MDC] *#show ap system-profile default

AP system profile "default"
