7. From the T
rust 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, DHCP
ACK, 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.
8. 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.
9. In the Rate Limit (pps) field, specify the rate limit value for DHCP snooping purposes.
