Cisco Router Dhcp Not Working

Cisco Router Dhcp Not Working

If your Cisco router’s DHCP is not working correctly, try a few troubleshooting steps, as mentioned below.

  • Step 1: Check whether the DHCP client interfaces are up and configured correctly.
  • Step 2: Also, check whether the DHCP server is up and has an IP address.
  • Step 3: Enable Debug dhcp detail to check if the DHCP is sending DHCP Discover messages.
  • Step 4: If it can send a DHCP Discover message, then there is no problem with the DHCP client.
  • Step 5: Check for the DHCP pool in the DHCP server using the “show ip dhcp pool” command.
  • Step 6: Use the “show ip sockets” command to check the listening ports of the router.
  • Step 7: If the DHCP is not responding to any ports, check whether the DHCP is disabled.
  • Step 8: To enable the DHCP server, use the command “service dhcp” and then check for the sockets again using the “show ip sockets” command.
  • Step 9: If the router is responding to a port number, it indicates that the DHCP service is active.
  • Step 10: Verify that the Cisco router’s DHCP is running correctly. If not, contact our technical support team by clicking the Call button available on this screen.
