secondary port
In EAPS, the secondary port is a port on the master node that is
designated the secondary port to the ring. The transit node ignores the
secondary port distinction as long as the node is configured as a
transit node.
sFlow
sFlow allows you to monitor network traffic by statistically sampling
the network packets and periodically gathering the statistics. The
sFlow monitoring system consists of an sFlow agent (embedded in a
switch, router, or stand-alone probe) and an external central data
collector, or sFlow analyzer.
SFP
Small form-factor pluggable. SFP is a specific type of GBIC, designed
for use with small form factor connectors. These transceivers offer
high speed and physical compactness.
6in4 tunnels
The 6in4 tunnels, which encapsulate IPv6 packets into IPv4 packets,
use dynamic routing protocols to establish connectivity between
several IPv6 networks through over the intervening IPv4 network. The
6in4 tunnel must be created at each tunnel endpoint. The IPv6 routing
protocol considers the 6in4 tunnel as a single IPv6 hop, even if the
tunnel comprises many IPv4 hops; the IPv6 protocol considers the
6in4 tunnel as a normal IPv6 point-to-point link. You can have many
6in4 tunnels per VR.
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.
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.
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.
