24.5.1 DHCP Snooping Port Configure

Use this screen to specify whether ports are trusted or untrusted ports for DHCP snooping.

Note: The Switch will drop all DHCP requests if you enable DHCP snooping and there are

no trusted ports.

You can also specify the maximum number for DHCP packets that each port (trusted or untrusted)

can receive each second. To open this screen, click Advanced Application > IP Source Guard >

DHCP Snooping > Configure > Port.

Renew DHCP

Snooping URL

Enter the location of a DHCP snooping database, and click Renew if you want the

Switch to load it. You can use this to load dynamic bindings from a different DHCP

snooping database than the one specified in Agent URL.

When the Switch loads dynamic bindings from a DHCP snooping database, it does not

discard the current dynamic bindings first. If there is a conflict, the Switch keeps the

dynamic binding in volatile memory and updates the Binding collisions counter in the

DHCP Snooping screen (Section 24.4 on page 229).

Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses

these changes if it is turned off or loses power, so use the Save link on the top

navigation panel to save your changes to the non-volatile memory when you are done

configuring.

Cancel Click this to reset the values in this screen to their last-saved values.
