In a dual or triple NIC configuration, you use two network interfaces for connectivity to two separate network segments. One network segment is used for switch connectivity to Communication Manager, and the other network segment for is used for client and media connectivity (LAN, VLAN, or WAN). The NICs must be on separate networks or network segments. In a dual or triple NIC configuration, the client network is referred to as the production (or public) network, and the Communication Manager segment is referred to as the private network segment.
The private network segment should contain one subnet; this is the only supported configuration. You can configure any default gateway for public and private network segments. However, Avaya recommends using a public gateway as the default gateway to enable access to AE Services through both public and private network segments. After deployment, you must add static routes through CLI to make AE Services accessible from the private network segment.
Note:
For NIC configuration, you must use the static IPv4 or static dual stack (IPv6 and IPv4) address (if applicable).
Caution:
If you need to use the IPv6 architecture, it must be dual stack (IPv6 and IPv4).
Only IPv6 is not supported.
From Release 10.1 and later, AE Services checks the NICs configuration, where the number of NICs should not be more than three, and the name of the NICs must be eth0 to eth2 (eth0, eth1 or eth2) depending on the number of NICs configured.
Important:
When you install the AE Services software, always use the following settings for a dual NIC configuration:
See Required network interface (NIC) settings for more information.
