to the server. The no operation of this command sets the reforward policy of DHCPv6

packets with option 38 as replace.

 Parameters: None.

 Default: Using replace mode to replace option 38 of current packets with system’s own.

 Command Mode: Global configuration mode

 Usage Guide: Since DHCPv6 client packets may already include option 38 information,

corresponding processing policy of DHCPv6 SNOOPING is requested to develop. If the

reforward policy is set as replace, option 38 has to be enabled in advance. The system

disables option 38 of DHCPv6 SNOOPING by default.

 Example: Set the reforward policy of DHCPv6 packets with option 38 as keep for

DHCPv6 SNOOPING.

 Switch(Config)# ipv6 dhcp snooping subscriber-id policy keep

4.1.18 ipv6 dhcp snooping subscriber-id select delimiter

 Command: ipv6 dhcp snooping subscriber-id select (sp | sv | pv | spv) delimiter

WORD (delimiter WORD | )

 no ipv6 dhcp snooping subscriber-id select delimiter

 Function: Configure user configuration options to generate subscriber-id. The no form

of this command restores to its original default configuration, i.e. vlan name together

with port name.

 Parameters: (sp | sv | pv | spv), a selection from combinations of slot, port and vlan,

among which sp represents slot and port, sv represents slot and vlan, pv represents

port and vlan, and spv represents slot, port and vlan.

 WORD, the delimiter between slot, port and vlan which ranges among

(#|.|,|;|:|/|space). Note that there're two delimiter WORDs here, of

which the former is the delimiter between slot and port while the latter

is that between port and vlan.

 Default: Null.

 Command Mode: Global configuration mode

 Usage Guide: This command has no effect on ports with self-defined subscriber-id. If a

user redefines subscriber-id of the port after configuring the command, the user-

defined one prevails. This configuration is null by default.

 Example:

 Swithc(config)# ipv6 dhcp snooping subscriber-id select sv delimiter #

4.1.19 ipv6 dhcp use class

 Command: ipv6 dhcp use class

 no ipv6 dhcp use class

 Function: This command enables DHCPv6 server to support DHCPv6 class during

address assignment, the no operation of this command disables it without removing

the relative DHCPv6 class information that has been configured.

 Parameters: None.
