Concept Guide

Column Description
Entry created
Timestamp showing the time the AP registered with the controller.
Last activity
Timestamp showing the last time the AP communicated with the
controller. An AP typically sends keepalive messages every
minute.
Reboots
Number of times power to the AP cycled off and then on again.
Reboots also known as “hard” restarts.
Bootstraps
Number of times the AP restarted. Bootstraps are also known as
“soft” restarts.
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.
Port
The controller port used by the AP, in the format
<slot>/<module>/<port>.
High throughput
Shows if high-throughput (802.11n) features are enabled or
disabled.
Mode
Shows the operating modes for the AP.
l AP: Device provides transparent, secure, high-speed data
communications between wireless network devices and the
wired LAN.
l AM: Device behaves as an air monitor to collect statistics,
monitor traffic, detect intrusions, enforce security policies,
balance traffic load, self-heal coverage gaps, etc.
Band
The RF band in which the AP should operate:
l 802.11g = 2.4 GHz
l 802.11a = 5 GHz
Channel
Channel number for the AP 802.11a/802.11n physical layer. The
available channels depend on the regulatory domain (country).
Secondary Channel
The secondary channel number for the AP. The secondary channel
is a 20 MHz channel used in conjunction with the primary channel
to create a 40 MHz channel for high-throughput clients.
High-throughput capable APs use only the primary channel to
communicate with 20 MHz clients. The secondary channel is used
for transmissions with 40 MHz capable high-throughput clients.
EIRP
Current effective Isotropic Radiated Power (EIRP).
