HiPath AP 3610/3620 Resetting every 20 to 30 Seconds upon First Install


Userlevel 3
Article ID: 12610

Products
AP3610, AP3620

Changes
New install, or adding new Access Points (APs) to a HiPath Wireless Controller (HWC).

Symptoms
The AP resets every 20 to 30 seconds after it gets a DHCP address.
Error message displayed on the AP's local console port, or via SSH to the AP's IP address (default SSH login:
code:
admin
; password:
code:
new2day
):
code:
ktrapMonitor: process (cap) is missing


Cause
This is due to a misconfiguration of the DHCP scope Option 78, whereby an option other than "
code:
Byte
" (for example, "
code:
IP
" or "
code:
String
") was sent by the DHCP server to the AP.

Solution
In a switched environment, remove the incorrectly configured Option 78 from the DHCP server.
In a routed environment, correctly configure Option 78 on the DHCP server, necessary in order to use the server with HiPath Wireless Access Points on a different subnet:
  1. Assuming a Windows-based server, go to "[code]Control Panel -[/code]> [code]Administrative Tools -[/code]> [code]DHCP[/code]". Notice that the DHCP server now is down.
  2. To configure the SLP options; right-click on the server and choose "[code]Set Predefined Options...[/code]".[list]
Set a
code:
Name
(e.g. "
code:
SLP DA
"), use
code:
Data type
"
code:
Byte
", check the
code:
Array
box, use
code:
Code
"
code:
78
", set a
code:
Description
(e.g. "
code:
SLP Option for HiPath Controller
"); then click
code:
OK
.
  • To configure the server options, right-click the
    code:
    Server Option
    line below the server and choose "
    code:
    Configure Options...
    ". Find the option
    code:
    78
    and enter the appropriate data.
      In the mandatory
      code:
      Data Entry Byte
      box (using
      code:
      Decimal
      format), type
      code:
      0
      (can be overridden by a static IP) or
      code:
      1
      (overrides a static IP) then click
      code:
      Add
      . Then type the IP address of the HiPath Wireless controller, adding each octet separately. For example; for address
      code:
      192.168.1.200
      , type
      code:
      1
      (mandatory value) , click
      code:
      Add
      , type
      code:
      192
      , click
      code:
      Add
      , type
      code:
      168
      , click
      code:
      Add
      , and so on. When done, type
      code:
      OK
      .
    • To create the DHCP scope, right-click on the server and choose "
      code:
      New Scope...
      ". When the Wizard starts, follow all steps to configure the scope. Upon completion select "
      code:
      Yes, I want to activate this scope now
      ", then click
      code:
      Next
      >.
    • To authorize the DHCP server into Active Directory, from the pulldown menu go to "
      code:
      Action -
      >
      code:
      Authorize
      ".
    • To start the service, right-click on the server and choose "
      code:
      All Tasks -
      >
      code:
      Restart
      ".[/list]
