33.4 DHCP Snooping Troubleshooting Help

33.4.1 Monitor and Debug Information

The “debug ip dhcp snooping” command can be used to monitor the debug information.

33.4.2 DHCP Snooping Troubleshooting Help

If there is any problem happens when using DHCP Snooping function, please check if the problem is caused

by the following reasons:

 Check that whether the global DHCP Snooping is enabled;

 If the port does not react to invalid DHCP Server packets, please check that whether the port is set as a

non-trusted port of DHCP Snooping.
