I am currently trying to configure two 1142N APs (AIR-LAP1142N-A-K9) to be stand alone APs. I have followed the PDFs




I set up the switch to provide DHCP and confirmed that each AP is indeed assigned an IP address. I can also ping each device. However when trying to browse to the GUI it fails to connect. So I tried to configure it via the CMD line. The enable mode does not give the option to configure interfaces as you would expect in enable mode nor does it give the option to enter global exec. example of the out put below.





Exec commands:

  cd               Change current directory

  clear            Reset functions

  clock            Manage the system clock

  crypto           Encryption related commands.

  debug            Debugging functions (see also 'undebug')

  delete           Delete a file

  dir              List files on a filesystem

  disable          Turn off privileged commands

  enable           Turn on privileged commands

  exit             Exit from the EXEC

  fsck             Fsck a filesystem

  help             Description of the interactive help system

  led              LED functions

  lock             Lock the terminal

  login            Log in as a particular user

  logout           Exit from the EXEC

  lwapp            lwapp exec commands

  mkdir            Create new directory

  monitor          Monitoring different system events

  more             Display the contents of a file

  name-connection  Name an existing network connection

  no               Disable debugging functions

  ping             Send echo messages

  pwd              Display current working directory

  release          Release a resource

  reload           Halt and perform a cold restart

  rename           Rename a file

  renew            Renew a resource

  rmdir            Remove existing directory

  send             Send a message to other tty lines

  set              Set system parameter (not config)

  show             Show running system information

  systat           Display information about terminal lines

  terminal         Set terminal line parameters

  test             Test subsystems, memory, and interfaces

  traceroute       Trace route to destination

  undebug          Disable debugging functions (see also 'debug')

  upgrade          Upgrade software

  verify           Verify a file

  where            List active connections

It seems that the IOS on this device does not have the capability to configure the AP as stand alone or that it has been disabled. How do I get into the CMD line to configure the AP for deployment?
Secondly since I could not configure it via the CMD line I attempted to connect to it via the GUI like I said above. This fails. I ran an NMAP to find out what is open and found that nothing but port 23 is open. What is the deal here? Is the web GUI shut off by default? Am I just totally missing something? I think I dies a little inside after this...help please?
