Description
Use ipv6 dhcp snooping vlan enable to enable DHCPv6 snooping for a specific VLAN.
Use undo ipv6 dhcp snooping vlan enable to disable DHCPv6 snooping for a specific VLAN.
By default, DHCPv6 snooping is disabled for a VLAN.
After DHCPv6 snooping is enabled globally and then enabled for a VLAN, the DHCPv6 snooping device records DHCPv6 snooping entries according to the DHCPv6 packets received in the VLAN. Meanwhile, upon receiving a DHCPv6 request from a client in the VLAN, the device forwards the packet through trusted ports rather than any untrusted port in the VLAN, thus reducing network traffic.
Examples
# Enable DHCPv6 snooping for VLAN 1.
<Sysname> system-view [Sysname] vlan 1 [Sysname-vlan1] ipv6 dhcp snooping vlan enable
