When enabled, the DHCP snooping feature generates a log message when an invalid
packet is received and dropped by the interface.

If the incoming rate of DHCP packets per second exceeds the configured burst interval
per second, the port shuts down. If the rate limit value is N/A, then the burst interval is
also nonapplicable, and rate limiting is disabled.
11. In the Burst Interval(secs) field, specify the burst interval value for rate limiting purposes on
this interface.
If the rate limit is N/A, then the burst interval is also nonapplicable, and the field displays
N/A.
12. Click the Apply button.
Your settings are saved.
Configure Static DHCP Bindings
You can view, add, and remove static bindings in the DHCP snooping bindings database and
to view or clear the dynamic bindings in the bindings table.
 To configure static DHCP bindings:

The default password is password. If you added the switch to a network on the Insight
app before and you did not yet change the password through the local browser interface,
enter your Insight network password.
