DHCP: Relay Agent
• The CyberSWITCH does not have Compression ENABLED
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).

[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

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.
