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A virtual circuit which is dynamically created and torn down when no longer
active.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:
z HP OpenView can discover the interface
z The interface is IP addressable
z The interface responds to RMON groups 1 through 9 queries
z The interface will transmit all traps from the probe
z 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.
