Glossary
A
ACL—Access control list. This list includes a series of rules that group the traffic by class, and allow/deny
certain classes of packets. VCM uses IMC's ACL Management function to determine match rules for
network traffic classification.
Add-on Module—Like other IMC modules, VCM can be installed and uninstalled separately in IMC
system.
C
CIR—Committed information rate. The CIR specifies the average rate allowed by the target VMs to
transmit or forward packets. In the practical environment, H3C recommends that you control
the traffic bandwidth to be less than the CIR value.
Connection—Binding a vNIC with a VSI Type version. When a vNIC accesses to the network from a new
location, the VSI Type version must be migrated on the corresponding switch.
D
Device—In IMC, device indicates any router, switch, server, desktop computer, or other machine that
participates in the flow of traffic across a network.
E
EVB—Edge virtual bridge. EVB is the environment where physical end stations contain multiple virtual
end stations that participate in the bridged LAN.
I
ISP—Internet service provider. An ISP is an organization that provides access to the Internet.
L
LAN —Local area network. The LAN supplies networking capability to a group of computers in close
proximity to each other, such as in an office building, a school, or a home.
The defining characteristics of LANs, in contrast to wide area networks (WANs), include their usually
higher data-transfer rates, smaller geographic area, and lack of the need for leased telecommunication
lines.
N
Network—It is a management facility of the VCM service module, with which you can assign VLANs for
transferring the traffic between VMs and clients, as well as assign the VSI types for controlling the traffic
between VMs and clients. In addition, with network management, you can authorize one or more
operators or operator groups to manage the VSI types assigned to the network.
O
Operation—It is an action in the service unit of the VSI Type. A service unit consists of one or more
operations.
P
Physical Server—The physical server in which the virtual software is installed. You can configure many
virtual machines on one physical server.
