26.6.1 DHCP Snooping Port Configure

Use this screen to specify whether ports are trusted or untrusted ports for DHCP snooping.
Note: If DHCP snooping is enabled but there are no trusted ports, DHCP requests cannot
reach the DHCP server.
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 >
IPv4 Source Guard Setup > DHCP Snooping > Configure > Port.

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
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.
