ES-2126C/D:
26-Port L2 Managed Fast Ethernet Switch with 2 SFP/GBIC Gigabit Dual Media
Benefits
QoS with four priority queues
Key Features
Standard compliance
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.

---IEEE 802.3u 100Base-TX Ethernet

---IEEE 802.3ab 1000Base-TX Ethernet

---IEEE 802.3x flow control capability
---ANSI/IEEE 802.3 auto-negotiation
---IEEE 802.1q VLAN
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.
RoHS Compliance
Subscriber Interface
---24 10/100Mbps and 2 Gigabit
Ethernet ports
---Port 25,26 are Gigabit TP/SFP Fiber
auto sense
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.
---Auto-Negotiation and Auto-MDI/MDIX
---Backpressure flow control for half
duplex.
---802.3x flow control for full duplex.
---Connector: 24 RJ-45 and 2 dual
media, RJ-45/SFP
Isolated Group provides protection for certain ports
Performance
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.
Switching capacity:
---Non-blocking switch fabric supports up
to 24FE+2GbE ports
---8 K MAC addresses
Mac-based 802.ad LACP with automatic link fail-over
---256k packet buffer and 128k control
memory
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.
---The maximum throughput is 8.8Gbps
---With 64 bytes packets throughput is
6.547Mpps
802.1x Access Control improves network security
---Store and Forward)Port-Pair Latency
is less 5 microseconds with any
ethernet packet length
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.
VLAN
---Provides the wire speed forwarding
rate
---Supports SVL/IVL configuration to
meet your VLAN requirement
---Port-base VLAN
802.1d Compatible & 802.1w Rapid Spanning Tree
---IEEE802.1q tag-base VLAN, 4094
max, up to 256 active VLANs including
static plus dynamic entry
---IEEE802.1q tag-base VLAN
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.

Overview
ES-2126C/D is a Managed Fast Ethernet
switch that supports SNMP, Web UI and
CLI management interface and with 24 10/
100Base-TX (RJ-45 connectors) and 2
Gigabit dual media(RJ-45/SFP or RJ-45/
GBIC) ports. It is a standard switch that
meets all IEEE 802.3/u/x/z Gigabit, Fast
Ethernet specifications. In addition, the
switch implements the QoS (Quality of
Service), VLAN, Mac Filtering Policy, Port
Mirror, VLAN and full L2 protocols. It has a
rich feature set suitable for streaming VoIP,
video, and data traffics for multimedia
applications.
In this switch, Port 25, 26 supports two
types of media --- TP and SFP/GBIC Fiber
(LC, BiDi-SC...); both ports support 10/100/
1000Mbps TP or 1000Mbps SFP/GBIC
Fiber with auto-detected function.
1000Mbps SFP/GBIC Fiber transceiver is
used for high-speed connection expansion.
