Term Definition
vNet/Virtual Connect Ethernet
Network
A
standard Ethernet Network consists of a sin
g
le 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)
A
n uplink port or a
g
roup 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.

Custom Port Speed** Manually set FlexNIC speed (up to Maximum value defined)

FlexNIC or FlexHBA Adapter port settings on the fly (without
power no/off)
EtherChannel*
A
Cisco proprietary technolo
g
y that combines multiple NIC or
switch ports for greater bandwidth, load balancing, and
redundancy. The technology allows for bi-directional aggregated
network traffic flow.
FlexNIC**
One of four virtual NIC partitions available per FlexFabric
Adapter port. Each capable of being tuned from 100Mb to
10Gb
FlexHBA***
The second Physical Function providin
g
an HBA for either Fibre
Channel or iSCSI functions
IEEE 802.1Q
A
n 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
A
n 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.

administrator. Can NOT be manually overridden on the server
profile.
