Glossary

Subnet Mask

Identifies the subnet field of a network address and is a 32-bit Internet address written in dotted-decimal notation. A subnet mask is used to divide a network into sub networks.

SVC (Switched Virtual Circuit)

A virtual circuit which is dynamically created and torn down when no longer active.

Synchronous Data Link Control (SDLC)

This level 2 protocol was developed by IBM. While it is not actually a standard (as being defined by a standards organization) it is commonly used. All data transmissions are in frames, and the starting flag, address, and control fields are known as Header information and the FCS and ending flags are known as Trailer information.

TE

Terminal Equipment.

Telemetry Port

The Telemetry port only receives packets destined for the port’s IP address, can transmit packets onto the network, and is used for SNMP communications to the probe. It requires the IP Address, Subnet Mask, and Default Gateway IP Address fields. The following apply to Monitor/Transmit ports:

HP OpenView can discover the interface

The interface is IP addressable

The interface responds to RMON groups 1 through 9 queries

zThe interface will transmit all traps from the probe

The interface will transmit all extended RMON packet samples from Monitor-only ports, Monitor/Transmit ports, and itself.

Terminal

An input/output device that permits interaction with a probe or computer. The device can be a display and keyboard, or a personal computer. An ASCII terminal, or PC emulating an ASCII terminal, can be connected to the probe for configuration, monitoring, and troubleshooting the probe.
