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:

Assuming a Windows-based server, go to "
```
Control Panel -
```
>
```
Administrative Tools -
```
>
```
DHCP
```
". Notice that the DHCP server now is down.
To configure the SLP options; right-click on the server and choose "
```
Set Predefined Options...
```
".
- 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:
