IPv4 and IPv6

Last Updated : Apr 05, 2022 |

Avaya J100 Series IP Phones support IPv4 and IPv6 dual mode, as well as only IPv6 mode. All the IPv4 functionality is retained for IPv6. IPv6 protocol is enabled by default.

Avaya J100 Series IP Phones support the following combinations of IPv4 and IPv6 IP address configuration:

  • Dual mode: Both IPv4 and IPv6 addresses are configured by using static addressing.

  • Dual mode: Both IPv4 and IPv6 addresses are configured by using DHCP.

  • IPv4 only mode.

  • IPv6 only mode.

IPv6 auto-configuration

The auto-configuration process includes generating a link-local address, global addresses via stateless address auto-configuration (SLAAC), and the Duplicate Address Detection procedure for verifying that the addresses are unique.

On the phone, IPv6 address can be assigned to the interface in the following ways:

  • By using DHCPv6

  • By using SLAAC

  • Manually

For more information, see Configuring IPv6 from the phone menu.

Both DHCPv6 and stateless address auto-configuration may be used simultaneously.

Note:

Do not use DHCPv6 and SLAAC simultaneously for same subnet.

Avaya J100 Series IP Phones can have multiple IPv6 addresses, all of which can be SLAAC.

For more information about configuring parameters for assigning an IPv6 address, see IPv6 configuration.
