Auto-Healing
This chapter shows you how to configure auto-healing settings.
12.1 Auto-Healing Overview
Auto-healing allows you to extend the wireless service coverage area of the managed APs when one
of the managed APs fails.
12.2 Auto-Healing Commands
The following table identifies the values required for many of these commands. Other input values
are discussed with the corresponding commands.
The following table describes the commands available for auto-healing. You must use the
configure terminal
command to enter the configuration mode before you can use these
commands.

Input Values for Auto-Healing Commands
LABEL DESCRIPTION
interval
Enters the auto-healing interval time. The range is 5 ~ 30 minutes.
Table 34
Command Summary: Auto-Healing
COMMAND DESCRIPTION
[no] auto-healing activate
Turns on the auto-healing feature. Use the
no
parameter to turn it
off.
auto-healing healing-interval interval
Sets the interval that specifies how often the managed APs scan
their neighborhoods and report the status of neighbor APs to the
AP controller (UAG).
An AP is considered “failed” if the AP controller obtains the same
scan result that the AP is missing from the neighbor list of other
APs three times.
auto-healing healing-threshold
Sets a minimum signal strength. A managed AP is added to the
neighbor lists only when the signal strength of the AP is stronger
than the specified threshold.
auto-healing power-threshold <-50~-80>
Sets a power threshold (in dBm). This value is used to calculate
the power level (
power-threshold
+
margin
) to which the
neighbor APs of the failed AP increase their output power in order
to extend their wireless service coverage areas.
When the failed AP is working again, its neighbor APs return their
output power to the original level.
