NIC teaming restrictions

NIC teaming is suggested for redundancy unless a particular implementation recommends against it. There are two main kinds of NIC

teaming:

1 Switch Dependent—Also referred to as 802.3ad or Dynamic Link Aggregation. The switch dependent teaming method uses the LACP

protocol to understand the teaming topology. This teaming method provides Active-Active teaming and requires the switch to support

LACP teaming.

2 Switch Independent—This method uses the operating system and NIC device drivers on the server to team the NICs. Each NIC

vendor may provide slightly dierent implementations with dierent pros and cons.

NIC Partitioning (NPAR) can impact how NIC teaming operates. Based on restrictions implemented by NIC vendors related to NIC

partitioning, certain congurations preclude certain types of teaming.

The following restrictions are applicable to both Full Switch and SmartFabric modes:

1 If NPAR is NOT in use, both Switch Dependent (LACP) and Switch Independent teaming methods are supported.

2 If NPAR IS in use, only Switch Independent teaming methods are supported. Switch Dependent teaming is NOT supported.

The following restrictions are applicable to Switch Dependent (LACP) teaming:

1 The IDRAC shared LOM feature can only be used if “Failover” option on IDRAC is enabled

2 If the host OS is Windows, the LACP timer MUST be set to “slow” (also referred to as “normal”)

For the list of supported operating systems, see Dell EMC PowerEdge MX7000 Enclosure Installation and Service Manual.

NOTE

: In the fabric mode, if an LACP team is created with four port and you want to delete two ports from the LACP team, you

must delete the entire LACP team and create a new LACP team with two ports.

For detailed NIC teaming instructions, refer to the network adapter or operating system documentation.

CLI commands available in Fabric mode

When operating in Fabric mode, most of the switch conguration is managed through the OME–Modular GUI. Some OS10 functionality,

such as L3 routing, are disabled. Owing to the disabling, a switch operating in Fabric mode supports all OS10 show commands, but only the

below subset of CLI conguration commands:

• clock—Congure clock parameters.

• end—Exit to the EXEC mode.

• exit—Exit from current mode

• help—Display available commands.

• hostname—Set the system host name.

• interface—Congure or select an interface.

• ip name-server—Congure the IP address of up to three name servers

• logging—Congure system logging.

• management route—Congure the IPv4/IPv6 management route

• no—Delete or disable commands in Conguration mode.

• ntp—Congure Network time protocol.

• snmp-server—Congure SNMP server.

• username—Create or modify user credentials.

• spanning-tree

– disable— Disable spanning tree globally.

– mac-flush-timer— Set the time used to ush MAC address entries.
