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 >

DESCRIPTION
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 27.4 on page
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.
Click this to reset the values in this screen to their last-saved values.
