Setting The Dscp Value For Dhcpv6 Packets; Displaying And Maintaining The Dhcpv6 Relay Agent; Dhcpv6 Relay Agent Configuration Example; Network Requirements - HP 3600 v2 Series Configuration Manual

Step
3. Enable DHCPv6 relay agent
on the interface and specify a
DHCPv6 server.

Setting the DSCP value for DHCPv6 packets

An IPv6 packet header contains an 8-bit Traffic class field. This field identifies the service type of IPv6
packets. As defined in RFC 2474, the first six bits set the Differentiated Services Code Point (DSCP) value,
and the last two bits are reserved. Network devices use the DSCP value as a reference to determine the
packet priority for transmission.
To set the DSCP value for DHCPv6 packets:
Step
1. Enter system view.
2. Set the DSCP value for
DHCPv6 packets sent by
the DHCPv6 relay agent.
Displaying and maintaining the DHCPv6 relay
agent
Task
Display the DUID of the local device.
Display DHCPv6 server addresses
specified on the DHCPv6 relay
agent.
Display packet statistics on the
DHCPv6 relay agent.
Clear packets statistics on the
DHCPv6 relay agent.

DHCPv6 relay agent configuration example

Network requirements

As shown in
the DHCPv6 server is 2::2/64. The DHCPv6 client and server need to communicate via a DHCPv6 relay
agent (Switch A).
Command
system-view
ipv6 dhcp dscp dscp-value

Remarks
By default, DHCPv6 relay
agent is disabled and no
DHCPv6 server is specified on
the interface.
Remarks
N/A
Optional.
By default, the DSCP value in
DHCPv6 packets is 56.
