Item
Description
Interface
The interface associated with the rest of the data in the row. When
configuring the settings for one or more interfaces, this field identifies
each interface that is being configured.
Trust State
The trust state configured on the interface. The trust state is one of the
following:
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, IPv6 DHCP snooping enforces the following
security rules:
–
DHCPv6 packets from a DHCPv6 server (ADVERTISE,
REPLY, and RECONFIGURE) are dropped.
–
RELEASE and DECLINE messages are dropped if the MAC
address is in the snooping database but the binding's inter-
face is other than the interface where the message was
received.
–
DHCPv6 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
DHCPv6 server messages without validation.
Log Invalid Packets
The administrative mode of invalid packet logging on the interface.
When enabled, the IPv6 DHCP snooping feature generates a log mes-
sage when an invalid packet is received and dropped by the interface.
Rate Limit (pps)
The rate limit value for DHCPv6 packets received on the interface. To
prevent DHCPv6 packets from being used as a DoS attack when IPv6
DHCP snooping is enabled, the snooping application enforces a rate
limit for DHCPv6 packets received on untrusted interfaces. If the
incoming rate of DHCPv6 packets exceeds the value of this object dur-
ing the amount of time specified for the burst interval, the port will be
shutdown. You must administratively enable the port to allow it to
resume traffic forwarding.
Burst Interval (Sec-
onds)
The burst interval value for rate limiting on this interface. If the rate limit
is unspecified, then burst interval has no meaning.
