• IPv6 Routing—(Layer 3 only) Select to enable IPv6 routing. If this is not
enabled, the device acts as a host (not a router) and can receive
management packets, but cannot forward packets. If routing is enabled, the
device can forward the IPv6 packets.
• ICMPv6 Rate Limit Interval—Enter how often the ICMP error messages are
generated.
• ICMPv6 Rate Limit Bucket Size—Enter the maximum number of ICMP error
messages that can be sent by the device per interval.
• IPv6 Hop Limit—(Layer 3 only) Enter the maximum number of intermediate
routers on its way to the final destination to which a packet can pass. Each
time a packet is forwarded to another router, the hop limit is reduced. When
the hop limit becomes zero, the packet is discarded. This prevents packets
from being transferred endlessly.
DHCPv6 Client Settings
• Unique Identifier (DUID) Format—This is the identifier of the DHCP client
that is used by the DHCP server to locate the client. It can be in one of the
following formats:
- Link-Layer—(Default). If you select this option, the MAC address of the
device is used.
- Enterprise Number—If you select this option, enter the following fields.
• Enterprise Number—The vendors registered Private Enterprise number as
maintained by IANA.
• Identifier—The vendor-defined hex string (up to 64 hex characters). If the
number of the character is not even, a zero is added at the right. Each 2 hex
characters can be separated by a period or colon.
• DHCPv6 Unique Identifier (DUID)—Displays the identifier selected.
Click Apply. The IPv6 global parameters and DHCPv6 client settings are updated.

IPv6 Interface

An IPv6 interface can be configured on a port, LAG, VLAN, loopback interface or
tunnel.
As opposed to other types of interfaces, a tunnel interface is first created in the
IPv6 Tunnel page and then IPv6 interface is configured on the tunnel in this page.
