Avaya G3PBX manual Requirements for Dual NIC Configurations, When Connecting via the Mapd DLG

Security and Configuration

Restricting Administration Permissions

To ensure your environment’s security, it is recommended that you use multiple-level administration permission to control which users are allowed to grant administration permissions. For details, see “Controlling SDB Administration Access” in Chapter 4 of Avaya Computer Telephony, Telephony Services Administration and Maintenance (NETMANGD.PDF).

Configuring the Tserver for a Secure

LAN Gateway Connection

Although the Avaya CT server can be configured using a single NIC, it is recommended that you configure the Avaya CT server with dual NICs, as follows.

■Configure one NIC to communicate with the client LAN (or WAN). This NIC can be Ethernet (10BaseT, 100BaseT, or 1000BaseT), Token Ring, or Fiber Distributed Data Interface (FDDI).

■Configure the second NIC to communicate with the DLG (which could be either Co-Resident on the MultiVantage server or on the MAPD). The Co-Resident DLG can use Ethernet 10BaseT or 100BaseT and the MAPD DLG uses Ethernet 10baseT. This NIC should be on a private isolated segment.

There should be no IP forwarding on the Avaya CT server — that is, there should be no IP forwarding between the Network Interface Card (NIC) used for the DEFINITY LAN Gateway and the NIC used for client access.

Requirements for Dual NIC Configurations

Follow these requirements for the MAPD based DLG or the Co-Resident DLG.

When Connecting via the MAPD DLG

In a dual NIC configuration, the NIC used by the G3PD must be configured as follows:

■Ethernet 10BaseT

■Half duplex

■IP forwarding disabled

When Connecting via the Co-Resident DLG

In a dual NIC configuration, the NIC card used by the G3PD must be administered as follows:

■Ethernet 10BaseT or 100BaseT

■Half duplex

■IP forwarding disabled
