8-Port Gigabit (PoE+) Ethernet Smart Managed Pro Switch with (2 SFP or 2 Copper Ports and)
9. From the Trust Mode menu, select the desired trust mode:
• Disabled. The interface is considered to be untrusted and could potentially be used
to launch a network attack. DHCP server messages are checked against the bindings
database. On untrusted ports, DHCP snooping enforces the following security rules:
- DHCP packets from a DHCP server (DHCPOFFER, DHCPACK, DHCPNAK,
DHCPRELEASEQUERY) are dropped.
- DHCPRELEASE and DHCPDECLINE messages are dropped if the MAC address
is in the snooping database but the binding's interface is other than the interface
where the message was received.
- DHCP packets are dropped when the source MAC address does not match the
client hardware address if MAC address validation is globally enabled.
• Enabled. The interface is considered to be trusted and forwards DHCP server
messages without validation.
10. From the Invalid Packets menu, select the packet logging mode.
When enabled, the DHCP snooping feature generates a log message when an invalid
packet is received and dropped by the interface.
11. In the Rate Limit (pps) field, specify the rate limit value for DHCP snooping purposes.
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 None, he burst interval is also
nonapplicable, and rate limiting is disabled.
12. In the Burst Interval (secs) field, specify the burst interval value for rate limiting purposes
on the interface.
If the rate limit is N/A, then the burst interval is also nonapplicable, and the field displays
N/A.
13. 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:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Access the switch on-network and
connected to the Internet on page 19 or Access the switch off-network on page 30.
