a length of less than 128. The no operation of this command restores subscriber-id in option 38 to
vlan name together with port name such as "Vlan2+Ethernet1/0/2".
Parameters:
subscriber-id, user-defined content of option 38
Default:
Set subscriber-id in option 38 to vlan name together with port name.
Command Mode:
Port mode
Usage Guide:
Because option 38 information added by switch may associate with third-party DHCPv6 servers,
users can specify subscriber-id content based on server condition when standard subscriber-id of
the switch cannot satisfy the demand of server. The vlan name together with physical port name is
used as subscriber-id in option 38 by default.
Example:
Enable abc as subscriber-id of DHCPv6 option 38.
Switch(Config-if-Ethernet1/0/1)#ipv6 dhcp snooping subscriber-id abc
