NIC Partitioning (NPAR) can impact how NIC teaming operates. Based on restrictions that
are implemented by the NIC vendors that are related to NIC partitioning, certain
configurations preclude certain types of teaming. The following restrictions are in place for
both Full Switch and SmartFabric modes.
• If NPAR is not in use, both switch dependent (LACP) and switch independent
teaming methods are supported.
• If NPAR is in use, only switch independent teaming methods are supported. Switch
dependent teaming is NOT supported.
If switch-dependent (LACP) teaming is going to be used the IDRAC shared LAN on
Motherboard (LOM) feature can only be used if the Failover option on IDRAC is enabled.
Also, if Microsoft Windows is the host operating system, the LACP timer MUST be set to
Slow.
To change the timing, see the following:
• Windows 2012R2 – Update adds support for the slow timer in LACP in Windows
Server 2012 R2 - Instructions 2012R2
• Windows 2016 – LACP Timer is configured incorrectly when you create a NIC
Team for LBFO - Instructions 2016
