ipv6 dhcp ping packets

Use the ipv6 dhcp ping packets global configuration command to specify the number of packets a

Dynamic Host Configuration Protocol for IPv6 (DHCPv6) server sends to a pool address as part of a

ping operation. To prevent the server from pinging pool addresses, use the no form of this command.

This command is available only if the switch is running the metro IP access image and you have

configured a dual IPv4 and IPv6 Switch Database Management (SDM) template on the switch.

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.

The DHCPv6 server pings a pool address before assigning it to a requesting client. An unanswered ping

indicates that the address is not in use and the server assigns the address to the requesting client.

Setting the number argument to 0 turns off the DHCPv6 server ping operation.

This example specifies two ping attempts by the DHCPv6 server before further ping attempts stop:

Switch(config)# ipv6 dhcp ping packets 2
