Chapter 26 DHCP Snooping

XMG1930 Series User’s Guide

231

When the DHCP server responds, the Switch removes the information in the Agent Information field
before forwarding the response to the original source.

You can configure this setting for each source VLAN. This setting is independent of the DHCP relay
settings.

26.4.1.4 Configuring DHCP Snooping

Follow these steps to configure DHCP snooping on the Switch.

1

Enable DHCP snooping on the Switch.

2

Enable DHCP snooping on each VLAN, and configure DHCP relay option 82.

3

Configure trusted and untrusted ports, and specify the maximum number of DHCP packets that each
port can receive per second.

4

Configure static bindings.
