Introduction
LED Indicators
There are system diagnostic LEDs and Ethernet Port LEDs located on the front panel of the RocketLinx ES8108/ES8108F.
The LED indicators provide administrators with real-time system status. The following table describes the function of each
LED indicator Refer to the figure in Front Panel on Page 7 for LED locations.
Packet Forwarding Ability
The RocketLinx ES8108/ES8108F features a packet filtering function for broadcast packet control protection and Quality of
Service (QoS). Both features can provide higher performance in a crowded network through traffic filtering and prioritization.
This subsection will introduce the principles of traffic control and forwarding precedence, including Broadcast control and
Quality of Service.
Broadcast Control
The RocketLinx ES8108/ES8108F begins to drop broadcast packets with DA (destination address) equal to
FF:FF:FF:FF:FF:FF if the received broadcast packets are more than the threshold – 198 packets/ per second at 100Mbps or 19
packets / per second at 10Mbps link speed.
All ports are enabled with this function by default to provide better network performance and prevent congestion caused by the
flooding of broadcast packets.
Quality of Service
The RocketLinx ES8108/ES8108F supports the frame type priority function, where high priority packets will be queued to a
high priority queue to share more bandwidth. The ratio of bandwidth of the high priority to the low priority queue is 8:1. After
8 high priority packets are processed, then 1 low priority packet is processed.
Both the RocketLinx ES8108 and RocketLinx ES8108F can examine the specific bits of VLAN Tag and TCP/IP TOS of IPv4
and IPv6.

IEEE 802.1Q tag based CoS RocketLinx ES8108/ES8108F User Guide: 2000514 Rev. B - 9
Introduction
IEEE 802.1Q tag based CoS
The RocketLinx ES8108/ES8108F checks the 3 bits of the priority field carried by a VLAN tag and maps it to the
corresponding priority. A packet with a priority field ranging from 0 to 3 will be treated as a low priority packet, and will be
stored in a low priority queue. A packet with a priority field ranging from 4 to 7 will be treated as a high priority packet, and
will be stored in the high priority queue.
IEEE 802.1Q Type of Service for IPv4 /IPv6 packet
The RocketLinx ES8108/ES8108F also provides the IP layer CoS (Class of Service) function by recognizing the priority octet
and mapping it to the corresponding priority. For an IPv4 packet, it is embedded in the TOS (Type of Service) Octet.
IPv4 Frame Format

10 - RocketLinx ES8108/ES8108F User Guide: 2000514 Rev. B IEEE 802.1Q Type of Service for IPv4 /IPv6 packet
Introduction
For an IPv6 data packet, the Traffic Class Octet is used to differentiate the Class of Service. When this function is enabled, the
RocketLinx ES8108/ES8108F will automatically recognize the IP version and capture either the TOS field (IPv4) or Traffic
Class field (IPv6) and distribute the packet into the High or Low Queue.

Connecting the Ethernet Ports
You can use the following information to connect standard Ethernet cables between the RocketLinx ES8108/ES8108F 10/
100BASE-TX Ethernet ports and the network nodes. The Fast Ethernet ports support 10BASE-T and 100BASE-TX, full- or
half-duplex modes.
All the Fast Ethernet ports automatically detect the signal from the connected devices to negotiate the link speed and duplex
mode. Auto MDI/MDIX allows you to connect another switch, hub, or workstation without changing straight-through or
crossover cables. Crossover cables cross-connect the transmit lines at each end to the received lines at the opposite end.
The Ethernet cables use Pins 1, 2, 3, and 6 of an 8-pin RJ45 connector. The signals of these pins are converted by the automatic
MDIX function, as shown in the following table.
Connect one side of an Ethernet cable into any switch port and connect the other side to your attached device. The LINK/ACT
LED is lit when the cable is correctly connected. Always make sure that the cables between the switches and attached devices
(for example, switch, hub, or workstation) are less than 100 meters (328 feet).
The wiring cable types and maximum cable length are as follows.
• 10BASE-T: 2-pair UTP/STP Category 3, 4, 5 cable, EIA/TIA-568 100-ohm (100 meters)
• 100BASE-TX: 2-pair UTP/STP Category 5 cable, EIA/TIA-568 100-ohm (100 meters)
