Parameter Description
Bootstrap threshold Number of consecutive missed heartbeats on a GRE tunnel (heartbeats
are sent once per second on each tunnel) before an AP rebootstraps. On
the controller, the GRE tunnel timeout is 1.5 x bootstrap-threshold; the
tunnel is torn down after this number of seconds of inactivity on the
tunnel. The supported range is 1-65535, and the default value is 8.
Double Encrypt This parameter applies only to remote APs. Use double encryption for
traffic to and from a wireless client that is connected to a tunneled SSID.
When enabled, all traffic is re-encrypted in the IPsec tunnel. When
disabled, the wireless frame is only encapsulated inside the IPsec tunnel.
All other types of data traffic between the controller and the AP (wired
traffic and traffic from a split-tunneled SSID) are always encrypted in the
IPsec tunnel.
Dump Server (For debugging purposes.) Specifies the server to receive a core dump
generated when an AP process crashes.
NOTE: To send the core dump file to the controller flash memory
instead of a dump server, access the command-line interface and issue
the command ap-crash-transfer.
Heartbeat DSCP Assign a DSCP value to AP heartbeats to prioritize heartbeats traveling
over low-speed links. The supported range is 0-63, and the default value
is 0. For more information, see Prioritizing AP heartbeats on page 563.
Maintenance Mode Enable or disable AP maintenance mode.
This setting is useful when deploying, maintaining, or upgrading the
network.
If enabled, APs stop flooding unnecessary traps and syslog messages to
network management systems or network operations centers when
deploying, maintaining, or upgrading the network. The controller still
generates debug syslog messages if debug logging is enabled.
Number of IPSEC retries Number of times the AP will try to create an IPsec tunnel with the master
controller before the AP will reboot. If you specify a value of 0, and AP
will not reboot if it cannot create the IPsec tunnel. The supported range
of values is 0-1000 retries, and the default value is 85 retries.
Maximum Request Retries Maximum number of times to retry AP-generated requests, including
keepalive messages. After the maximum number of retries, the AP
either tries the IP address specified by the bkup-lms-ip (if configured) or
reboots.
Request Retry Interval Interval, in seconds, between the first and second retries of AP-
generated requests. If the configured interval is less than 30 seconds,
the interval for subsequent retries is increased up to 30 seconds.
Root AP Defines a remote AP as the root AP in a branch network with a multi-AP
hierarchy.
