Usage Guidelines To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 {default | vlan)
global configuration command, and reload the switch.
When you configure the DHCPv6 server to detect conflicts, it uses ping. The client uses neighbor
discovery to detect clients and reports to the server through a DECLINE message. If an address conflict
is detected, the address is removed from the pool, and the address is not assigned until the administrator
removes the address from the conflict list.
Examples This is an example of the output from the show ipv6 dhcp conflict command:
Switch# show ipv6 dhcp conflict
Pool 350, prefix 2001:1005::/48
