Resource Id: Lan1SetIPv6:202403
You can use these settings to configure IPv6 address support on the LAN.
  • The IP Office licensing and configuration requirements for remote extensions are the same for IPv6 as for IPv4. The IP Office treats any extension using an IPv6 global unicast address not issued by IP Office DHCP as a remote extension.

Configuration Settings

These settings are not mergeable. Changes to these settings require a reboot of the system.
Field
Description
IPv6
Default = Disabled
IP Office supports IPv6 on Linux-based IP Office systems only. When enabled, the IP Office system supports IPv6 features on the LAN.
  • If using the IP Office self-signed certificates, you must regenerate the self-signed IP Office certificates after enabling IPv6 support.
  • You can also configure the IP Office system IPv6 address settings through the server Platform View/Web Control menus.
  • Avaya supports IPv6 on IP Office LAN1. Avaya also supports IPv6 on LAN2 but only when IPv6 is enabled on LAN1 also.
IP Address
Default = Blank
Sets or shows the IP Office IPv6 address on the LAN.
  • You cannot change the address if the IP Office is a DHCPv6 client.
  • You cannot change the address if the IP Office is using Stateless Address Auto-configuration (SLAAC).
  • If setting a static address, the IP Office supports /64 subnet prefixes only.
    • The IP Office supports IPv6 addresses in the following formats:
      • Full address: For example, 2001:0000:040F:0000:0000:0000:805B:001B.
      • Replace one series of :0000: parts with ::. For example, 2001:0000:040F::805B:001B.
      • Replace any individual :0000: parts with :0:. For example, 2001:0:040F::805B:001B.
      • Remove leading 0 zeros after any : colon. For example, 2001:0:40F::805B:1B.
Gateway
Display = Blank
Displays the default gateway settings for routing. If not using DHCP, you can edit the field to change the setting.
Stateless Address Auto-configuration (SLAAC)
Default = Disabled
If enabled:
  • The IP Office uses SLAAC (RFC4862) to set an IPv6 unicast address for the LAN, and to obtain details of the network IPv6 routers.
  • IP Office Manager disables all other settings on the tab.
  • Avaya assumes that dynamically addressed devices on the LAN use SLAAC for their IPv6 addresses.
Number of DHCP IP Addresses
Default = 24. Range = 1 to 500.
This defines the number of sequential IP addresses available for DHCP clients.
DHCP Mode
Default = DHCP Client.
Set the IP Office IPv6 DHCP mode for the LAN. The options are:
Option
Description
Server Stateful
In response a DHCPv6 request, the IP Office issues information such as domain name, DNS server address, and file server address. This includes issuing an IPv6 address.
  • The IP Office maintains details of the IPv6 addresses it has issued.
Server Stateless
In response to a DHCPv6 request, the IP Office issues information such as domain name, DNS server address, and file server address. However:
  • The IP Office does not issue an IPv6 IP address.
  • The IP Office expects other dynamically-addressed devices on the LAN to obtain their IPv6 address using mechanisms such as SLAAC.
Client
The IP Office system request IPv6 address information from a DHCPv6 server on the LAN.
Disabled
The IP Office system is not a DHCPv6 client or server.
Advanced
Default = Disabled.
When functioning as a DHCP server, you can configure the IP Office with multiple address pools from which it can issue IPv6 addresses.
  • When enabled, IP Office Manager displays an additional DHCP Pools (IPv6) tab.
