Appendices 329
A protocol used to transfer keyboard, video and mouse information between a DS1800 digital
switch or DSR 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
software client connects directly to the target device using a web browser. No DS1800 digital
switches, DSI5100, CPS or CCM appliances or DSR switches are used for browser sessions.
Cascade device
A device that connects between a DS1800 digital switch, DSR switch, CPS appliance or CCM
appliance and a target device, or connects to a DS1800 digital switch, DSR switch, CPS
appliance or CCM appliance and is not, in itself, a target device. Examples of cascade devices
include a cascade switch and an SPC power control device.
Cascade switch
A cascade switch is an analog KVM switch connected to a DS1800 digital switch or DSR
switch port or DSRIQ module. A cascade switch expands the number of connections allowed
on a DS1800 digital switch or DSR 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 software servers in a DSView software system. Database replication ensures that all
database changes made at the hub server or spoke servers are replicated to all DSView
software servers in the DSView software system.
The DSView 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 software version 3.0 with a hub server running DSView software version 3.1.1.
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
