Page 102: Configuring Ip Session
To make access users go online successfully, you must configure a static route between the egress gateway and the DHCP server on the S9300&S9300E.

Page 112: Dhcpv6 Configuration
5 DHCPv6 Configuration DHCPv6 Configuration About This Chapter Currently, the S9300&S9300E can function as only the DHCP relay agent on IPv6 networks. This document describes how to configure Dynamic Host Configuration Protocol for IPv6 (DHCPv6) relay. 5.1 Introduction to DHCPv6 DHCPv6 is designed for IPv6 addressing and is used to allocate IPv6 addresses and other network configuration parameters to hosts.
Page 113: Introduction To Dhcpv6
The DHCP Unique Identifier (DUID) identifies a DHCPv6-enabled device including the DHCPv6 client and is used for verification between DHCPv6-enabled devices. The S9300&S9300E uses the DUID Based on hardware type, Link-layer Address and Time (DUID-LLT) to identify DHCPv6-enabled devices. Figure 5-1 shows the format of the DUID-LLT.
Page 114: Dhcpv6 Features Supported By The S9300&S9300E
The link layer address is the MAC address. 5.2 DHCPv6 Features Supported by the S9300&S9300E Currently, the S9300&S9300E supports only the DHCPv6 relay function, and cannot function as the DHCPv6 server or client. Typical Networking of DHCPv6 Figure 5-2 shows a typical networking of DHCPv6.
Page 115 To prevent a large number of messages of clients or relay agents from attacking the device, the S9300&S9300E can limit the rate of DHCPv6 messages to be forwarded. An alarm is generated when the number of discarded packets exceeds the threshold.
Page 116: Configuring Dhcpv6 Relay
DHCPv6 messages discarded 5.3.2 Enabling the DHCPv6 Relay Function You can enable the DHCPv6 relay function on a VLANIF interface of the S9300&S9300E, set the IPv6 address of the DHCPv6 server or the next hop relay agent, and specify the outbound interface of relay messages.
Page 117: Optional) Configuring The Remote Id
DHCPv6 server or the next hop relay agent needs to be specified. On the S9300&S9300E, up to eight interfaces can be enabled with the DHCPv6 relay function and each interface can be configured with up to eight destination addresses.
Page 118 Currently, a remote ID can contain a maximum of 247 bytes. When the S9300&S9300E functions as the DHCPv6 relay agent, it processes the remote ID as follows: The S9300&S9300E directly receives messages from DHCPv6 clients. When constructing a Relay-Forward message, the S9300&S9300E adds the remote ID to the Relay-Forward...
Page 119: Optional) Configuring Rate Limit Of Dhcpv6 Messages
Rate limit of DHCPv6 messages is enabled and the maximum transmission rate of DHCPv6 messages is set. By default, rate limit of DHCPv6 messages is disabled on the S9300&S9300E. Step 4 Run: dhcpv6 packet-rate drop-alarm enable The alarm function for DHCPv6 messages discarded when the rate of DHCPv6 messages exceeds rate limit.
Page 120: Maintaining Dhcpv6
5.4.1 Clearing the Statistics About DHCPv6 Messages Passing Through the DHCP Relay Agent If the S9300&S9300E is enabled with the DHCPv6 relay function, the system collects statistics about DHCPv6 messages passing through the DHCP relay agent. To clear the statistics about DHCPv6 messages passing through the DHCPv6 relay agent, you can use the command in the user view or system view.
