into one of four traffic class queues. The QoS (Quality of service) functionality supports
Tag priority, IPV4, and IPV6. Tag priority precedes IPV4 and IPV6. All of the factors
possibly affecting the packet switching is based on the incoming port, IEEE 802.1p(tag),
IPv4 Type of Service (TOS) or Differentiated Services (Diff-Serv), IPv6 Traffic Class,
802.1Q VLAN ID, destination MAC address or source MAC address. The devices also
contain a high-performance address look-up engine with support for up to 8192 active
nodes, and a 1 Mbit frame buffer memory. The MAC units in the devices comply fully
with the applicable sections of IEEE 802.3.
The frames are placed in queues with assigned priorities ranging from 3(highest ) to
0(lowest). The sequence of transmission of QoS weighted frames is as follows:
3, 2, 3, 1, 3, 2, 3, 0, 3, 2, 3, 1, 3, 2, 3
The frames assigned to higher priorities will have more opportunity to be transmitted,
while the frames assigned to lower priorities will have less opportunity for transmission.
The higher priority frames are given a larger fraction of the total time available for MAC.
Multi-cast is supported by the switch, and incoming multi-cast frames are forwarded to
all ports IEEE 802.3q VLAN is also supported. Packets tagged with VLAN ID will be
forwarded to the appropriate port with the VLAN ID and priority information still in the
tag.
Power-Over-Ethernet
The CX-6p-PoE can provide power to up to four devices connected to Ethernet ports 1-4
via the 802.3at Power over Ethernet (PoE) standard. The CX-6p-PoE can provide up to
30W of power to each device individually, but can only provide 60W of power total to all
four devices. For example, it could provide 15W simultaneously to four devices, or 30W
simultaneously to two devices, but it could not provide 30W simultaneously to all four
devices.
To power an Ethernet device from the CX-6p-PoE, simply plug the Ethernet cable
connected to that device into one of ports 1-4 on the front of the CX-6p-PoE. The CX-
6p-PoE will automatically detect the device and provide power to it. The LED above and
to the right of the powered device’s port will illuminate to indicate power is being
delivered.
The CX-6p-PoE will monitor the voltage and power being delivered at each port, and will
display that information on the user web page. Power delivery to each port can be
manually disabled or enabled through the web page.
