Glossary
Nonbroadcast Multiaccess (NBMA) Networks
Network that supports two or more attached routers but does not have broadcast
capability.
Open Shortest Path First (OSPF)
OSPF is a link-state routing protocol that supports the distribution of routing information
between routers belonging to a single autonomous system.
Path Cost
A number from 1 to 65535. This number indicates how much a port is contributing to the
total cost of the path to the root bridge when the port is the root port.
Point-to-Point
OSPF interface state that indicates the interface is operational and is connected to either a
physical point-to-point network or to a virtual link. Upon entering this state, the router
attempts to form an adjacency with its neighboring router. The router sends hello packets.
Point-to-Point Network
A network that joins a single pair of routers.
Port Utilization Summary
Use the Port Utilization Summary to identify the traffic patterns of SSR ports. This
summary indicates the percentage of traffic that is being transmitted and received on each
port. For a detailed description of an example summary, see
“Monitoring Port Utilization”
on page 374
.
Precedence Value
QoS parameter associated with the IP or IPX packet fields that SSR uses to break ties if
packets match more than one flow. You assign a precedence from 1 ñ 7 with each field. The
highest precedence value is 1 and the lowest is 7.
Privileged Password
Password you are prompted for when you start Configuration Expert. This password logs
you in to Configuration Expert so that you can then use that utility to configure your SSR.
Probe Messages
Messages sent in a reverse path from the receiver back to the source. As a probe message
passes from hop to hop, it collects information such as interface address and packet counts
from each router.
Pruning
Operation DVMRP routers perform to exclude interfaces not in the shortest path tree.
Quality of Service (QoS)
Set of parameters that do the following:
•
Assign priorities to different types of traffic.
