IAGNOSIS

DHCP: Relay Agent

In this case, the CyberSWITCH will respond to all attempts by the peer to open CCP with 

a TERM-ACK frame. The connection will operate uncompressed. (Note: a device that 
supports compression but has it disabled will typically do the exact same thing).

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.
