Glossary
Glossary-32 PortMaster Configuration Guide
SNMP
Simple Network Management Protocol. A protocol defined in RFC 1157, used for
communication between management consoles and network devices.
speaker
A single BGP router that is able to communicate with other routers that run BGP. When
two BGP speakers communicate with each other, they are called BGP
peers .
SPID
Service profile identifier. A number used by some service providers to define the services
to which an ISDN device subscribes. The ISDN device uses the SPID when accessing the
switch that initializes the connection to a service provider.
station
See host .
stub area
In OSPF, an area into which no external routes are imported. A stub area cannot contain
autonomous system border routers and cannot be a transit area for virtual links.
Summary advertisements external to the area are by default imported into the stub area
but might be squelched to further reduce area database size. In this case, the default route
advertisement by the autonomous system border routers handle all routes external to the
area.
subnet mask
A 32-bit netmask used to indicate the bits of an IP address that are being used for the
subnet address. Compare
netmask .
summarization
The process of combining routing information from one routing protocol into another for
advertisement. For example, the PortMaster summarizes non-BGP route information it
receives internally via the Interior Gateway Protocol (IGP) OSPF or RIP, or via a static
route, into BGP for advertisement to BGP internal and external peers. Summarized
routing information must comply with BGP advertisement policy rules before
advertisement. Compare
propagation .
SVC
Switched virtual circuit. A connection established between two physical circuits, such as
an ordinary telephone call. The call creates a virtual circuit between the originator and
the party called.
