VLAN Double Tagging (Q-in-Q)
VLAN double-tagging can be useful
for customers such as Internet Service
Providers (ISP), allowing them to use

IEEE 802.1x Authentication
This protocol uses an authentication
server to store details of each user
who has been granted access to the
network. The authentication criteria can
be a computer MAC address, but can
also include IP address, username and
password etc. Initially, the switch port
will be blocked, but when a computer
connects, it will only be connected to
the authentication server. If the request
to access the network is granted, then
the switch will be programmed with
the necessary details, such as VLAN
membership. This type of security
simplifies the task of the network

network. The authentication criteria can

simplifies the task of the network
administrator. They can keep all of their
security data on a server and not have to
program each switch. This scenario has
the added benefit of allowing users to
connect to any port on the network.

Voice VLAN
Voice VLAN segregates VoIP traffic from
Ethernet traffic and applies it to a higher
QoS. This ensures high voice quality
for phone conversations, as voice and
data traffic share the same switch and
Ethernet ports. It protects time-sensitive
voice traffic from being flooded by
data traffic share the same switch and
Ethernet ports. It protects time-sensitive
voice traffic from being flooded by
other data traffic, such as multicasts and
broadcasts.
sFlow
sFlow is an industry-standard technology
for monitoring high-speed switched
networks. It gives complete visibility
into the use of networks enabling
performance optimization, accounting
and billing for usage and defense against
security threats. Sampled packets sent to
a collector ensure it always maintains a
real-time view of network traffic.
