Protocol Data
Units (PDUs)
A unit of data that is specified in a protocol of a specific layer and that
consists of protocol-control information of the specific layer and possibly
user data of that layer.
Provider
Backbone Bridge
(PBB)
To forward customer traffic across the service provider backbone, SPBM
uses IEEE 802.1ah Provider Backbone Bridging (PBB) MAC-in-MAC
encapsulation, which hides the customer MAC (C-MAC) addresses in a
backbone MAC (B-MAC) address pair. MAC-in-MAC encapsulation
defines a BMAC-DA and BMAC-SA to identify the backbone source and
destination addresses.
quality of service
(QoS)
QoS features reserve resources in a congested network, allowing you to
configure a higher priority to certain devices. For example, you can
configure a higher priority to IP deskphones, which need a fixed bit rate,
and, split the remaining bandwidth between data connections if calls in
the network are more important than the file transfers.
Read Write All
(RWA)
An access class that lets users access all menu items and editable
fields.
remote login
(rlogin)
An application that provides a terminal interface between hosts (usually
UNIX) that use the TCP/IP network protocol. Unlike Telnet, rlogin
assumes the remote host is, or behaves like, a UNIX host.
remote monitoring
(RMON)
A remote monitoring standard for Simple Network Management Protocol
(SNMP)-based management information bases (MIB). The Internetwork
Engineering Task Force (IETF) proposed the RMON standard to provide
guidelines for remote monitoring of individual LAN segments.
resilient packet
ring (RPR)
A shared packet edge ring connection, where both paths around the ring
carry traffic, that allows double bandwidth on each ring.
reverse path
forwarding (RPF)
Prevents a packet from forging its source IP address. Typically, the
system examines and validates the source address of each packet.
route flapping An instability that is associated with a prefix, where the associated prefix
routes can exhibit frequent changes in availability over a period of time.
routing policy A form of routing that is influenced by factors other than the default
algorithmically best route, such as the shortest or quickest path.
Secure Copy
(SCP)
Secure Copy securely transfers files between the switch and a remote
station.
Secure Shell (SSH) SSH uses encryption to provide security for remote logons and data
transfer over the Internet.
Secure Shell (SSH)
