6to4 tunnels The 6to4 tunnels are one way to send IPv6 packets over IPv4 networks. This
transition mechanism provides a way to connect IPv6 end-site networks by
automatically tunnelling over the intervening IPv4 Internet. A special IPv6 routing
prefix is used to indicate that the remaining part of the external routing prefix
contains the IPv4 endpoint address of a boundary IPv6 router for that site that
will process IPv6-in-IPv4-encapsulated packets. You can have only one 6to4
tunnel per VR.
slow path This term refers to the data path for packets that must be processed by the
switch CPU, whether these packets are generated by the CPU, removed from
the network by the CPU, or simply forwarded by the CPU.
SMF Single-mode fiber. SMF is a laser-driven optical fiber with a core diameter small
enough to limit transmission to a single bound mode. SMF is commonly used in
long distance transmission of more than 3 miles; it sends one transmission at a
time.
SMON Switch Network Monitoring Management (MIB) system defined by the IETF
document RFC 2613. SMON is a set of MIB extensions for RMON that allows
monitoring of switching equipment from a SNMP Manager in greater detail.
SNMP Simple Network Management Protocol. SNMP is a standard that uses a
common software agent to remotely monitor and set network configuration and
runtime parameters. SNMP operates in a multivendor environment, and the
agent uses MIBs, which define what information is available from any
manageable network device. You can also set traps using SNMP, which send
notifications of network events to the system log.
SNTP Simple Network Time Protocol. SNTP is used to synchronize the system clocks
throughout the network. An extension of the Network Time Protocol, SNTP can
usually operate with a single server and allows for IPv6 addressing.
SSH Secure Shell, sometimes known as Secure Socket Shell, is a UNIX-based
command interface and protocol of securely gaining access to a remote
computer. With SSH commands, both ends of the client/server connection are
authenticated using a digital certificate, and passwords are protected by being
encrypted.
SSL Secure Sockets Layer. SSL 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.
