Troubleshooting DHCP relay agent configuration
Symptom
DHCP clients cannot obtain any configuration parameters via the DHCP relay agent.
Analysis
Some problems may occur with the DHCP relay agent or server configuration.
Solution
To locate the problem, enable debugging and execute the display command on the DHCP relay agent
to view the debugging information and interface state information.
Check that:
• The DHCP is enabled on the DHCP server and relay agent.
• The address pool on the same subnet where DHCP clients reside is available on the DHCP server.
• The DHCP server and DHCP relay agent are reachable to each other.
• The relay agent interface connected to DHCP clients is correlated with a correct DHCP server group
and the IP addresses of the group members are correct.
