Term Definition 
vNet/Virtual Connect Ethernet 

Network 

A standard Ethernet Network consists of a single broadcast 

domain.  However, when “VLAN Tunnelling” is enabled within 

the Ethernet Network, VC will treat it as an 802.1Q Trunk port, 

and all frames will be forwarded to the destined host untouched. 

Shared Uplink Set (SUS) 

An uplink port or a group of uplink ports, where the upstream 
switch port(s) is configured as an 802.1Q trunk.  Each associated 

Virtual Connect Network within the SUS is mapped to a specific 

VLAN on the external connection, where VLAN tags are removed 

or added as Ethernet frames enter or leave the Virtual Connect 
domain. 

Auto Port Speed** 

Let VC automatically determine best Flex NIC speed 

Custom Port Speed** 

Manually set Flex NIC speed (up to Maximum value defined) 

DCC** 

Device Control Channel: method for VC to change Flex-10 NIC 

port settings on the fly (without power no/off) 

EtherChannel* 

A Cisco proprietary technology that combines multiple NIC or 

switch ports for greater bandwidth, load balancing, and 

redundancy. The technology allows for bi-directional aggregated 
network traffic flow. 

Flex NIC** 

One of four virtual NIC partitions available per Flex-10 Nic port.  

Each capable of being tuned from 100Mb to 10Gb 

Flex-10 Nic Port** 

A physical 10Gb port that is capable of being partitioned into 4 

Flex NICs 

IEEE 802.1Q 

An industry standard protocol that enables multiple virtual 

networks to run on a single link/port in a secure fashion through 

the use of VLAN tagging. 

IEEE 802.3ad 

An industry standard protocol that allows multiple links/ports to 

run in parallel, providing a virtual single link/port. The protocol 
provides greater bandwidth, load balancing, and redundancy. 

LACP Link 

Aggregation Control Protocol (see IEEE802.3ad) 

LOM LAN-on-Motherboard. 

Embedded 

network adapter on the system 

board 

Maximum Link Connection 

Speed** 

Maximum Flex NIC speed value assigned to vNet by the network 

administrator.  Can NOT be manually overridden on the server 

profile. 

Multiple Networks Link Speed 

Settings** 

Global Preferred and Maximum Flex NIC speed values that 

override defined vNet values when multiple vNets are assigned to 
the same Flex NIC 

MZ1 or MEZZ1; LOM 

Mezzanine Slot 1; LAM on Motherbard/systemboard NIC 

Network Teaming Software 

A software that runs on a host, allowing multiple network 

interface ports to be combined to act as a single virtual port. The 

software provides greater bandwidth, load balancing, and 
redundancy. 

pNIC** 

Physical NIC port.  A Flex NIC is seen by VMware as a pNIC 

Port Aggregation Combining ports to provide one or more of the following benefits: 

greater bandwidth, load balancing, and redundancy.
