Glossary
MIB
Management Information Base; a list of entries
that may be queried or modified. The LSB4
supports the Bridge MIB, which contains lists
of bridge-specific information. The information
contained in MIBs can be retrieved or modified
using SNMP commands; for more information,
refer to Appendix D.
Multicast
A packet to be sent to more than one network
address. There are many different types of mul-
ticast packets; for example, IP multicasts, sent
only to IP addresses.
Overrun
An overrun results when there is not sufficient
memory on the LSB4 for it to receive packets.
Overruns may occur when the network is ex-
tremely busy; for example, when the number of
packets per second traveling on the network
exceeds the LSB4Õs forwarding or filtering rate.
When an overrun occurs, the LSB4 will ignore
packets (rather than forward them) until suffi-
cient memory becomes available.
RFC
Request for Comments; a document that lists a
standard method of completing a particular
task. RFCs are available over the internet at no
cost; for details, refer to Appendix D.
Root
A particular switch designated by the Span-
ning Tree Algorithm. This switch regularly
sends out
BPDU packets (see page i) to enable
other switches to monitor the network (in order
to prevent network loops). For details, see
page B-3.
