Examples
# Enable DHCPv6 client state debugging. When DHCPv6 client stateless autoconfiguration is enabled
on VLAN-interface 2, output similar to the following example is generated:
<Sysname> debugging ipv6 dhcp client state
*Nov 23 16:15:39:118 2006 Sysname DHCPC6/7/DebugState:
Interface Vlan-interface2, stateless client:
INIT --> IDLE (O-flag received)
// The DHCPv6 client received an O-Flag change notification, and its state changed from INIT to IDLE.
# Enable DHCPv6 client packet debugging. When DHCPv6 client stateless autoconfiguration is enabled
on VLAN-interface 2, output similar to the following example is generated:
<Sysname> debugging ipv6 dhcp client packet
