AVSP (Avocent Video Session Protocol)
A protocol used to transfer keyboard, video and mouse information between a KVM switch
and a remote Video Viewer. AVSP operates over SSL encrypted TCP links. TCP/IP ports 8192
and 2068 are used by default, but may be configured to different port numbers.
Browser session
A type of target device session in which the target device contains a web server. The DSView
3 software client connects directly to the target device using a web browser, without directing
the connection through the unit.
Cascade device
A device that connects between a KVM switch or serial console appliance and a target device,
or connects to a KVM switch or serial console appliance and is not, in itself, a target device.
Examples of cascade devices include a cascade switch and a power device.
Cascade switch
A cascade switch is an analog KVM switch connected to a KVM switch port or IQ module. A
cascade switch expands the number of connections allowed on a KVM switch if the switch
supports the cascade protocol.
CCM appliance
A CCM console management appliance is an Avocent managed appliance that provides a
Telnet server and an SSH server for accessing serially attached devices over a standard TCP/IP
connection. Model numbers include the CCM850, CCM1650 and CCM4850 appliances.
Certificate authentication
Certificate authentication is the process of authenticating with a digital certificate.
CPS appliance
A CPS serial over IP network appliance is an Avocent managed appliance that provides a
Telnet server and an SSH server for accessing serially attached devices over a standard TCP/IP
connection. Model numbers include the CPS810 and CPS1610 appliances.
Database replication
Database replication is the process of distributing and keeping in sync the same database to all
DSView 3 servers in a DSView 3 software system. Database replication ensures that all
database changes made at the hub server or spoke servers are replicated to all DSView 3
servers in the DSView 3 software system.
The DSView 3 management software versions of the spoke server and hub server must match
in order to register the spoke server. For example, you may not register a spoke server running
DSView 3 software version 3.1 with a hub server running DSView 3 software version 3.2.
DHCP (Dynamic Host Configuration Protocol)
DHCP is an Internet protocol used to automate the configuration of computers using TCP/IP.
DHCP can be used to do the following:
• Assign IP addresses automatically
