GS-1208M: 8-Port Web-Smart Gigabit Ethernet Switch
Benefits
QoS with Four Priority Queues
Key Features
Standard Compliance
---IEEE 802.3 10Base-T Ethernet
(twisted-pair copper)
The QoS(Quality Of Service) feature provides four internal queues to support
four different classifications of traffic. High priority packet streams experience
less delay inside the switch, which supports lower latency for certain delay-
sensitive traffic. The GS-1208M could classify the packet as one of the four
priorities according to 802.1p priority tag or DSCP.
---IEEE 802.3u 100Base-TX Ethernet
(twisted-pair copper)
---IEEE 802.3ab 1000Base-T Ethernet
(twisted-pair copper)
---ANSI/IEEE 802.3 Auto-negotiation
RoHS Compliance
Port Mirroring
This mechanism helps track network errors or abnormal packet transmission
without interrupting the flow of data. Allow ingress traffic to be monitored by a
single port that is defined as mirror capture port. The mirror capture port can
be any 10/100 port, 10/100/1000 port. Mirroring multiple ports is possible but
can create congestion at the mirror capture port.
Subscriber Interface
---8 Gigabit Ethernet ports
---Auto-negotiation
---Provide the double tagging feature,
which is useful for ISP application.
---Provide the loop detection feature for
unmanaged environments.
---Supports TP interface auto MDI/MDI-
X function for auto TX/RX swap
---Supports 802.3x flow control pause
packet for full-duplex
Broadcast/Multicast/Unknown-Unicast Storm Control
To limit too many broadcast/multicast/unknown-unicast flooding in the
network, broadcast/multicast storm control is used to restrict excess traffic.
Threshold values are available to control the rate limit for each port. Packets
are discarded if the count exceeds the configured upper threshold.
---Provide these packets are longer than
1518 bytes, but shorter than 9728
bytes that is suitable for multimedia
application.
Trap Event for Exception Management
We use SNMP Trap mechanism to inform supervisor to know the instant
abnormal status of the switch.
---Back pressure flow control for half-
duplex
Build-in web-base management
Instead of using CLI interface, we provide a more convenient GUI for user.
We just need to configure switch via Web Browser. It is more quickly for user
to familiar with the method to control switch on the basis of this design.
---Supports 10/100Mbps auto-detect
half/full duplex and 1000Mbps at full
duplex
---Connector: 8 RJ-45 ports
