LED Indicators
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.
