Use the IPv6 DHCP Snooping Statistics page to view and clear per-interface statis-
tics about the DHCPv6 messages filtered by the IPv6 DHCP snooping feature. Only
interfaces that are enabled for IPv6 DHCP snooping and are untrusted appear in the
table.

4.4.4
DVLAN
DVLAN Tunneling allows the use of a second tag on network traffic. The additional
tag helps differentiate between customers in the Metropolitan Area Networks (MAN)
while preserving individual customer's VLAN identification when they enter their own
802.1Q domain.
With the introduction of this second tag, you do not need to divide the 4k VLAN ID
space to send traffic on an Ethernet-based MAN.
With DVLAN Tunneling enabled, every frame that is transmitted from an interface
has a new VLAN tag (S-tag) attached while every packet that is received from an
interface has a VLAN tag (S-tag) removed (if one or more tags are present).
DVLAN also supports up to 4 Tag Protocol Identifier (TPID) values per switch and the
ability to map these values to ports. This allows you to configure the same or different
TPIDs for different ports.
4.4.4.1
Configuration
The DVLAN Configuration page allows you to configure the Tag Protocol Identifier
(TPID) to include in frames transmitted by interfaces that are enabled for double
Item
Description
Interface
The interface associated with the rest of the data in the row.
MAC Verify Failures The number of DHCPv6 messages that were dropped because the
source MAC address and client hardware address did not match. MAC
address verification is performed only if it is globally enabled.
Client Ifc Mismatch
The number of packets that were dropped by IPv6 DHCP snooping
because the interface and VLAN on which the packet was received
does not match the client's interface and VLAN information stored in
the binding database.
DHCP Server Msgs
Received
The number of DHCPv6 server messages (ADVERTISE, REPLY,
RECONFIGURE, RELAY-REPL) that have been dropped on an
untrusted port.
