Chapter 19 Configuring Repeater and Standby Access Points and Workgroup Bridge Mode
Configuring a Hot Standby Access Point
Step 8
iapp standby poll-frequency
seconds
Sets the number of seconds between queries that the standby
access point sends to the monitored access point’s radio and
Ethernet ports. The default poll frequency is 2 seconds.
Step 9
iapp standby timeout seconds Sets the number of seconds the standby access point waits for a
response from the monitored access point before it assumes that
the monitored access point has malfunctioned. The default
timeout is 20 seconds.
Note You should increase the standby timeout setting if the
bridged path between the standby and monitored access
points can be lost for periods greater than 20 seconds
(during spanning tree recalculation, for example).
Note If the monitored access point is configured to select the
least congested radio channel, you might need to increase
the standby timeout setting. The monitored unit might
take up to 40 seconds to select the least congested
channel.
Step 10
iapp standby primary-shutdown (Optional) Configures the standby access point to send a Dumb
Device Protocol (DDP) message to the monitored access point to
disable the radios of the monitored access point when the standby
unit becomes active. This feature prevents client devices that are
associated to the monitored access point from remaining
associated to the malfunctioning unit.
Step 11
show iapp standby-parms Verify your entries. If the access point is in standby mode, this
command displays the standby parameters, including the MAC
address of the monitored access point and the poll-frequency and
timeout values. If the access point is not in standby mode, no iapp
standby mac-address appears.
Step 12
end Return to privileged EXEC mode.
Step 13
copy running-config
startup-config
(Optional) Save your entries in the configuration file.
