Problem:
The following message appears in the report log (after system initialization, or after the DHCP/
BOOTP Relay Agent has been enabled from MANAGE mode):
[DHCP-R] Failed to open UDP port (67), erc = <error return code>
Action:
This message indicated that an internal error occurred while trying to open a UDP port for use by
the DHCP/BOOTP Relay Agent. Therefore, the relay agent will not operate correctly. Contact your
Distributor or Customer Support.
Problem:
The following message is NOT found in the report log after system initialization:
[DHCP-R] Relay Agent enabled; UDP port (67) opened
Action:
This situation indicates that there was no attempt made to enable the DHCP/BOOTP Relay Agent.
1. Check the DHCP configuration. This can be done by using CFGEDIT, or by using the
dhcp
command from Manage Mode.
2. Make sure that the Relay Agent is enabled.
3. If desired, enter MANAGE mode, and use the
dhcp change
command to enable the Relay
Agent. (Note: CFGEDIT can also be used to change the Relay Agent configuration; but the
changes will not take effect until the system is restarted.)
4. When Manage Mode is exited, an attempt will be made to enable the Relay Agent.
5. Re-examine the report log for the “Relay Agent Enabled” message.
6. Remember to “commit” the Manage Mode configuration changes to make them permanent.
