Key Features
QoS with Four Priority
Queues
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. it can classify the packet as one of the four priorities according to 802.1p priority tag, DiffServ and/or IP TOS. The QoS operate at full wire speed. The actual scheduling at each egress port can be based upon a strict priority, weighted round robin or a mix of both.
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.
Q-in-Q VLAN for
performance & security
The VLAN feature in the switch offers the benefits of both security and performance. VLAN is used to isolate traffic between different users and thus provides better security. Limiting the broadcast traffic to within the same VLAN broadcast domain also enhances performance. VLAN support enabling advanced techniques such as “802.1Q-in-1Q” to be deployed.
Isolated Group, Provide
Secure for Certain Ports
The isolated group feature
allows certain ports to be designated as protected. All other ports
are non-isolated. Traffic between
isolated group
members are blocked. Traffic can only be sent from isolated group to
non-isolated group.
Mac-based 802.ad Lacp
with Automatic Link Fail-over
Dynamic fail-over means packets will not get assigned to any trunk member port that has failed. If one of the ports were to fail, traffic will automatically get distributed to the remaining active ports.
802.1x Access Control
Improve Network Security
802.1x features enable user authentication for each network access attempt. Port security features allow you to limit the number of MAC addresses per port in order to control the number of stations for each port. Static MAC addresses can be defined for each port to ensure only registered machines are allowed to access. By enabling both of these features, you can establish an access mechanism based on user and machine identities, as well as control the number of access stations.
802.1D Compatible &
802.1w Rapid Spanning Tree
For mission critical environments with multiple switches supporting STP, you can configure the switches with a redundant backup bridge path, so transmission and reception of packets can be guaranteed in event of any fail-over switch on the network.
2 Dual Media for Flexible
Fiber Connection
25, 26 dual media port are provided for flexible fiber connection. You can select to install optional transceiver modules in these slots for short, medium or long distance fiber backbone attachment. Use of the SFP will disable their corresponding built-in 10/100/1000Base-T connections.
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.
