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. Enable debugging and
execute the display command on the DHCP relay agent to view the debugging information and interface
state information for locating the problem.
Solution
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 routes between the DHCP server and DHCP relay agent are reachable.
• The relay agent interface connected to DHCP clients is correlated with correct DHCP server group
and IP addresses for the group members are correct.
