Infrastructure
Ethernet devices (end devices and cabling devices) can generally be divided into
two categories: unmanaged and managed devices:
b
the device.
b
(manage them) and access their internal information.
The ConneXium product line offers both types of device. There is a special category
of managed devices that allows access to the information in the devices, but these
devices cannot be controlled or configured.
Managed devices offer the following features:
b
traffic capacity of a network (features in this area include: message and port priority,
flow control, multicast filtering, broadcast limiting, IGMP snooping, VLAN, etc.).
b
one or more network segments, able to communicate with each other as if they
belonged to the same LAN.
VLANs are based on logical (rather than physical) links. The main advantage of
VLANs lies in the possibility of creating user groups based on the role of the
participants and not on their physical location or medium.
Since large/multicast data packets are transmitted exclusively within a virtual LAN,
the remaining data on the network are unaffected. The VLAN can also serve as a
security mechanism to block unwanted Unicast messages.
b
access that could result in changes in its configuration and impact the traffic going
through the switch (features in this area include: port security, read/write community
name, etc.).
The user can also configure the switch so that it blocks messages coming from
addresses of unauthorized "devices" connected to the switch.
b
all devices on the network.
