BenefitsBenefits
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. The ES-2126C/D 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. Q-in-Q, the use of
double VLAN tags is an efficient method for enabling Subscriber Aggregation.
This is very useful in the MAN.
Isolated Group provides protection 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 improves 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.
