algorithm. This protocol is more ecient and scalable than vector-distance routing protocols. OSPF
features include least-cost routing, ECMP routing, and load balancing. Although OSPF requires CPU
power and memory space, it results in smaller, less frequent router table updates throughout the
network. This protocol is more ecient and scalable than vector-distance routing protocols.
PEAP
Protected Extensible Authentication Protocol is an IETF draft standard to authenticate wireless LAN
clients without requiring them to have certificates. In PEAP authentication, first the user authenticates
the authentication server, then the authentication server authenticates the user. If the first phase is
successful, the user is then authenticated over the SSL tunnel created in phase one using EAP-Generic
Token Card (EAP-GTC) or Microsoft Challenged Handshake Protocol Version 2 (MSCHAP V2). (See also
EAP-TLS/EAP-TTLS.)
RIP
This IGP vector-distance routing protocol is part of the TCP/IP suite and maintains tables of all known
destinations and the number of hops required to reach each. Using Routing Information Protocol,
routers periodically exchange entire routing tables. RIP is suitable for use only as an IGP.
SSL
Secure Socket Layer is a protocol for transmitting private documents using the Internet. SSL works by
using a public key to encrypt data that is transferred over the SSL connection. SSL uses the public-and-
private key encryption system, which includes the use of a digital certificate. SSL is used for other
applications than SSH, for example, OpenFlow.
syslog
A protocol used for the transmission of event notification messages across networks, originally
developed on the University of California Berkeley Software Distribution (BSD) TCP/IP system
implementations, and now embedded in many other operating systems and networked devices. A
device generates a messages, a relay receives and forwards the messages, and a collector (a syslog
server) receives the messages without relaying them.
syslog uses the UDP as its underlying transport layer mechanism. The UDP port that has been assigned
to syslog is 514. (RFC 3164)
VLAN
The term VLAN is used to refer to a collection of devices that communicate as if they are on the same
physical LAN. Any set of ports (including all ports on the switch) is considered a VLAN. LAN segments
are not restricted by the hardware that physically connects them. The segments are defined by flexible
user groups you create with the CLI.
