Glossary
Glossary-20 PortMaster Configuration Guide
location
A dial-out destination.
location table
A database on the PortMaster where location settings are stored. See location .
lockstep
A feature of BGP on the PortMaster that ensures consistency of routing information
between the BGP and non-BGP routers within its autonomous system. Lockstep forces
the PortMaster to advertise a route learned from an internal BGP peer only when it has
learned the same route via an Interior Gateway Protocol (IGP)—OSPF or RIP—or a static
route. See also
transit service .
LSA
Link state advertisement. The state of the router links (interfaces), networks, summaries,
or autonomous system external links of an OSPF router that it periodically advertises.
Link states are also advertised when a link state changes.
M
MAC address
Media access control address. A unique 48-bit binary number—usually represented as a
12-digit hexadecimal number—encoded in the circuitry of a device to identify it on a
LAN.
Management Information Base
See MIB .
management station
A workstation or PC capable of retrieving and analyzing statistical information from
networked Simple Network Management Protocol (SNMP) agents.
master
In Multichassis PPP, the PortMaster through which an initial connection for a given user
is made. Every master also has a corresponding slave. Masters are for a given connection
only, and a PortMaster that functions as a master for one user’s connection can be a slave
for a different user’s connection. See also
slave .
