◆

Network traffic may be disrupted when malicious DHCPv6 messages are 

received from an outside source. DHCPv6 snooping is used to filter 

DHCPv6 messages received on an unsecure interface from outside the 

network or fire wall. When DHCPv6 snooping is enabled globally by this 

command, and enabled on a VLAN interface by the 

ipv6 dhcp snooping 

vlan

 command, DHCP messages received on an untrusted interface (as 

specified by the 

no ipv6 dhcp snooping trust

 command) from a device 

not listed in the DHCPv6 snooping table will be dropped. 

◆

When enabled, DHCPv6 messages entering an untrusted interface are 

filtered based upon dynamic entries learned via DHCPv6 snooping.

◆

Table entries are only learned for trusted interfaces. Each entry 

includes a MAC address, IPv6 address, lease time, binding type, VLAN 

identifier, and port identifier. 

◆

When DHCPv6 snooping is enabled, the rate limit for the number of 

DHCPv6 messages that can be processed by the switch is 100 packets 

per second. Any DHCPv6 packets in excess of this limit are dropped.

◆

Filtering rules are implemented as follows:

■

If global DHCPv6 snooping is disabled, all DHCPv6 packets are 

forwarded.

■

If DHCPv6 snooping is enabled globally, and also enabled on the 

VLAN where the DHCPv6 packet is received, DHCPv6 packets are 

forwarded for a 

trusted

 port as described below. 

■

If DHCPv6 snooping is enabled globally, and also enabled on the 

VLAN where the DHCP packet is received, but the port is 

not 

trusted

, DHCP packets are processed according to message type as 

follows:

DHCP Client Packet

■

Request: Update entry in binding cache, recording client’s 

DHCPv6 Unique Identifier (DUID), server’s DUID, Identity 

Association (IA) type, IA Identifier, and address (4 message 

exchanges to get IPv6 address), and forward to trusted port.

■

Solicit: Add new entry in binding cache, recording client’s DUID, 

IA type, IA ID (2 message exchanges to get IPv6 address with 

rapid commit option, otherwise 4 message exchanges), and 

forward to trusted port.

■

Decline: If no matching entry is found in binding cache, drop 

this packet.

■

Renew, Rebind, Release, Confirm: If no matching entry is found 

in binding cache, drop this packet.

■

If the DHCPv6 packet is not a recognizable type, it is dropped.
