A protocol that is used by a network node to determine the Internet Protocol (IP)
address of its Ethernet interfaces used for network booting.
bridge (or MAC Bridge)
An intelligent, protocol-independent, store-and-forward device that operates as a
Data Link layer relay. Used to connect similar or dissimilar local area networks
(LANs). A collection of LANs connected by bridges is referred to as an Extended
LAN.
brouter
A bridge with minimal routing capabilities. In general, a brouter can deliver least-
cost routing; some can also deliver minimal-load balancing.
CF state
The CF state displays the current path configuration of the A and B ports.
chassis
The physical housing of the hub.
community
A set of attributes that are managed as a group. Community names are used in SNMP
to control access. Each SNMP software request contains a community name that the
agent uses as a password to verify that the requester is authorized to access the
agent’s management information base (MIB) or a subset of that MIB.
Community names indicate whether or not the requester has read-only or read-write
authority.
In Digital’s implementation, MIBs are defined by the agent.
community string
A text string, also referred to as a community name, that is used as a password by an
SNMP agent to authenticate or verify that the network management station (NMS)
making the request is allowed access to the contents of the agent’s management
information base (MIB).
