Troubleshooting DHCP relay agent configuration
Symptom
DHCP clients cannot obtain any configuration parameters through the DHCP relay agent.
Analysis
Some problems might 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.
Verify that:
1. DHCP is enabled on the DHCP server and relay agent.
2. The DHCP server has an address pool on the same subnet as the DHCP clients.
3. The DHCP server and DHCP relay agent can reach each other.
4. 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.
