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 different implementations with different pros and cons. NIC Partitioning (NPAR) can impact how NIC teaming operates. Based on restrictions implemented by NIC vendors related to NIC partitioning, certain configurations 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 configuration 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 configuration commands: • clock-Configure clock parameters. • end-Exit to the EXEC mode. • exit-Exit from current mode • help-Display available commands. • hostname-Set the system host name. • interface-Configure or select an interface. • ip name-server-Configure the IP address of up to three name servers • logging-Configure system logging. • management route-Configure the IPv4/IPv6 management route • no-Delete or disable commands in Configuration mode. • ntp-Configure Network time protocol. • snmp-server-Configure SNMP server. • username-Create or modify user credentials. • spanning-tree - disable- Disable spanning tree globally. - mac-flush-timer- Set the time used to flush MAC address entries.

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
different
implementations with
different
pros and cons.
NIC Partitioning (NPAR) can impact how NIC teaming operates. Based on restrictions implemented by NIC vendors related to NIC
partitioning, certain
configurations
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
configuration
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
configuration
commands:
•
clock
—Configure
clock parameters.
•
end
—Exit to the EXEC mode.
•
exit
—Exit from current mode
•
help
—Display available commands.
•
hostname
—Set the system host name.
•
interface
—Configure
or select an interface.
•
ip name-server

•
management route
—Configure
the IPv4/IPv6 management route
•
no

Configuration
mode.
•

SNMP server.
•
username
—Create or modify user credentials.
•
spanning-tree
