• To configure multiple interfaces with the same settings, select the check box
associated with each interface.
• To configure all interfaces with the same settings, select the check box in the
heading row.
8. From the Trust Mode menu, select the trust mode:
• Disabled. The interface is considered to be untrusted and could potentially be
used to launch a network attack. DHCPv6 server messages are checked against
the bindings database. On untrusted ports, DHCPv6 snooping enforces the
following security rules:
• DHCPv6 packets from a DHCPv6 server are dropped.
• DHCPv6 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.
• DHCPv6 packets are dropped if the source MAC address does not match the
client hardware address and if MAC address validation is globally enabled.
• Enabled. The interface is considered to be trusted and forwards DHCPv6 server
messages without validation.
9. From the Invalid Packets menu, select the packet logging mode.
When enabled, the DHCPv6 snooping feature generates a log message when an
invalid packet is received and dropped by the interface.
10. In the Rate Limit (pps) field, specify the rate limit value for DHCPv6 snooping
purposes.
If the incoming rate of DHCPv6 packets per second exceeds the configured burst
interval per second, the port shuts down. If the rate limit is None (which is the default),
the burst interval is also not applicable, and rate limiting is disabled.
11. In the Burst Interval (secs) field, specify the burst interval in seconds for rate limiting
on the interface.
If the rate limit is N/A, the burst interval is not applicable.
12. Click the Apply button.
Your settings are saved.
13. To save the settings to the running configuration, click the Save icon.
