Troubleshooting Access Points Using Telnet or SSH
The controller supports the use of Telnet or Secure Shell (SSH) protocols to troubleshoot lightweight
access points. Using these protocols makes debugging easier, especially when the access point is unable
to connect to the controller.
•
To avoid potential conflicts and security threats to the network, the following commands are
unavailable while a Telnet or SSH session is enabled:
config terminal
,
telnet
,
ssh
,
rsh
,
ping
,
traceroute
,
clear
,
clock
,
crypto
,
delete
,
fsck
,
lwapp
,
mkdir
,
radius
,
release
,
reload
,
rename,
renew
,
rmdir
,
save
,
set
,
test
,
upgrade
.
•
Commands available during a Telnet or SSH session include:
debug
,
disable
,
enable
,
help
,
led
,
login
,
logout
,
more
,
no debug
,
show
,
systat
,
undebug
,
where
.
Using the controller CLI, follow these steps to enable Telnet or SSH access on lightweight access points.
Step 1
To enable Telnet or SSH connectivity on an access point, enter this command:
config ap
{
telnet
|
ssh
}
enable
Cisco_AP
Note
To disable Telnet or SSH connectivity on an access point, enter this command:
config ap
{
telnet
|
ssh
}
disable
Cisco_AP
Step 2
To save your changes, enter this command:
save config
Step 3
To see whether Telnet or SSH is enabled on an access point, enter this command:
show ap config general
