NonVolatile Random
Access Memory
(NVRAM)
Random Access Memory that retains its contents after electrical power
turns off.
out of band (OOB) Network dedicated for management access to chassis.
Packet Capture Tool
(PCAP)
A data packet capture tool that captures ingress and egress (on Ethernet
modules only) packets on selected ports. You can analyze captured
packets for troubleshooting purposes.
port A physical interface that transmits and receives data.
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.
Protocol
Independent
Multicast, Sparse
Mode (PIM-SM)
PIM-SM is a multicast routing protocol for IP networks. PIM-SM provides
multicast routing for multicast groups that can span wide-area and inter-
domain networks, where receivers are not densely populated. PIM-SM
sends multicast traffic only to those routers that belong to a specific
multicast group and that choose to receive the traffic. PIM-SM adds a
Rendezvous Point router to avoid multicast-data flooding. Use PIM-SM
when receivers for multicast data are sparsely distributed throughout the
network.
quality of service
(QoS)
QoS features reserve resources in a congested network, allowing you to
configure a higher priority for certain devices. For example, you can
configure a higher priority for 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.
Routing Information
Protocol (RIP)
A distance vector protocol in the IP suite, used by IP network-layer protocol,
that enables routers in the same AS to exchange routing information by
means of periodic updates. You often use RIP as a very simple interior
gateway protocol (IGP) within small networks.
Secure Copy (SCP)
Secure Copy securely transfers files between the switch and a remote
station.
