Referring to the above config, the organization is using DHCP Snooping within their network. A User on VLAN 29 on a new switch is complaining that an IP address is not being obtained. Which command should be configured on the switch interface to provide the user with network connectivity?
Understand the Problem
The question is asking what command should be configured on a switch interface to allow a user on VLAN 29 to obtain an IP address using DHCP Snooping. The issue is that the user is currently unable to get an IP address, indicating that the necessary configurations may not be applied to that VLAN or interface.
Answer
Configure 'ip dhcp snooping trust' on the switch interface.
The final answer is to configure the command 'ip dhcp snooping trust' on the switch interface.
Answer for screen readers
The final answer is to configure the command 'ip dhcp snooping trust' on the switch interface.
More Information
When DHCP snooping is enabled, switch ports are set to 'untrusted' by default to prevent unauthorized users from providing IP addresses. Setting the interface as 'trusted' allows DHCP communication.
Tips
A common mistake is to forget to specify the interface; this command should be run at the interface level, not globally.
