SYSTEM VERIFICATION

Verifying DHCP: Proxy Client

If you do not see this message in the report log, the DHCP Proxy Client has successfully performed its initialization processing.

If this message is contained in the report log, refer to DHCP Proxy Client Initialization in the Problem Diagnosis chapter.

VERIFYING THE PROXY CLIENT IS ENABLED

If the Proxy Client has been enabled via configuration, a relevant message will appear in the report log.

1.Examine the report log. Type: dr <return>

2.Look for any messages that begin with [DHCP-P].

3.If the Proxy Client has been enabled via configuration, the following message should appear:

[DHCP-P] Proxy Client enabled

If the above message was found in the report log, the Proxy Client has been successfully enabled.

If an error occurred while trying to enable the Proxy Client, the following message will be present in the report log:

[DHCP-P] Failed to register with the IP Address Pool Manager, erc=<error code>

If this error message is found in the report log, refer to Enabling the Proxy Client in the Problem Diagnosis chapter.

VERIFYING THE PROXY CLIENT IS OPERATIONAL

Once the DHCP Proxy Client manager has been successfully initialized and enabled, it should begin obtaining IP addresses from DHCP servers. The manager examines any WAN and WAN (Direct Host) network interfaces. It then attempts to satisfy the “number of IP addresses to pre- fetch” for each of these network interfaces.

UDP PORTS

In order to reach DHCP servers, the DHCP Proxy Client will open the BOOTPC UDP port, and possibly the BOOTPS UDP port. One or both of the following messages should then appear in the report log:

[DHCP-P] UDP port (67) opened

[DHCP-P] UDP port (68) opened

If neither of these error messages is found in the report log, refer to DHCP Proxy Client Operation in the Problem Diagnosis chapter.
