Network interface (NIC) settings

The NIC choices for all network interfaces are as follows:

importantImportant

AE Services defaults to auto-negotiation mode; it negotiates the network speed and duplex mode with the Ethernet switch. Both ends of the Ethernet link must be set to the same mode. Otherwise, a duplex mismatch will occur. Verify that both ends of the Ethernet link operate at the same desired speed and duplex settings.

Keep in mind the following:

  • Auto-neg is highly desired for Gigabit links.

  • Auto-neg or Lockdown is acceptable for 100-Megabit links.

  • Lockdown for Gigabit links is highly discouraged.

  • 10-Megabit and/or half-duplex operation is never acceptable and should be corrected.

For detailed information about using auto-negotiation and Lockdown, see Ethernet Link Guidelines at https://support.avaya.com/css/P8/documents/100121639.

noteNote

The NIC speed 1000, full duplex with auto-negotiate is supported if AE Services is connected to Communication Manager Processor Ethernet that has the same NIC settings.
