USER’S GUIDE

DHCP RELAY AGENT

The following sections provide instructions to verify that the DHCP/BOOTP Relay Agent is working properly.

VERIFYING DHCP RELAY AGENT INITIALIZATION

Regardless of whether or not the Relay Agent has been enabled via configuration, some initialization processing is always performed. If this initialization is successful, there should not be any warnings/errors written to the report log by the DHCP Relay Agent.

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

2.The dr command displays the system report log. Look for any messages that begin with:

[DHCP-R]

3.The following messages indicate that errors occurred during DHCP/BOOTP Relay Agent initialization processing:

[DHCP-R] Failed to allocated memory for transmit buffer pool

[DHCP-R] Relay Agent initialization failed

If you do not see either of these messages in the report log, the DHCP/BOOTP Relay Agent has successfully performed its initialization processing.

4.If either (or both) of the above messages are contained in the report log, try the following:

Look for the following messages after system initialization:

[DHCP-R] Failed to allocated memory for transmit buffer pool

[DHCP-R] Relay Agent initialization failed

These messages indicate that an error occurred during initialization of the DHCP/BOOTP Relay Agent. Therefore, the relay agent will not operate correctly. Contact your Distributor or Customer Support.

VERIFYING THE RELAY AGENT IS ENABLED

If the Relay Agent has been enabled via configuration, it will attempt to open a UDP port for use. A message describing the outcome of this operation will appear in the report log.

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

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

3.If the Relay Agent has been enabled via configuration, the following message should appear:

[DHCP-R] Relay Agent enabled; UDP port (67) opened

If the above message was found in the report log, the Relay Agent has been successfully enabled.
