## Symptoms

- * Fetching policy on a DAIP gateway fails with:

  ```
  
  External interface is not properly defined. Please run cpconfig to define it.
  Segmentation fault (core dumped)
  ```

* Fetching policy on a DAIP gateway under debug ('`fw -d fetch IP_of_MGMT`') shows:

  ```
  
  ExternalIF: >>NAME_of_INTERFACE<<
  cpii_get_interface_ip_and_netmask: Getting IP address and netmask for 'NAME_of_INTERFACE'
  cpii_get_interface_list_common: called with vrf 0, buffer (nil), buflen 0, skip_slaves 0, do_ipv6 0
  cpii_get_interface_list_ex_ex: called with vrf 0, buffer (nil), buflen 0, skip_slaves 0, do_ipv6 0
  cpii_get_interface_list_ex_ex: buffer given too small. Need XXX bytes
  cpii_get_interface_list_common: converted buffer_ex_len (XXX bytes) to buflen (YYY bytes)
  cpii_get_interface_list_common: done. returning -3
  ```

* After enabling generation of core dump files per [sk92764](http://supportcontent.checkpoint.com/solutions?id=sk92764) / [sk53363](http://supportcontent.checkpoint.com/solutions?id=sk53363), core dump files for '*fw_full* ' process were generated in the */var/log/dump/usermode/* directory during policy fetching.
