Taipei, March 6, 2008– Ruby Tech Corp., a leading
designer and manufacturer of innovative network products, today announced the new
24-Port L2 Plus Managed Fast Ethernet Switch + 2 TP/SFP Gigabit Dual Media – ES-2226C
Features and Functionality
ES-2226C, 24 Fast Ethernet + 2
Gigabit L2 Managed Switch, implemented 24 10/100Mbps TP + 2 Gigabit dual media
ports with TP/SFP(or GBIC), is a standard switch that meets all IEEE
802.3/u/x/z Gigabit, Fast Ethernet and Ethernet specifications. The switch can
be managed through RS-232 serial port via direct connection, or through
Ethernet port using Telnet or Web-based management unit, associated with SNMP
agent. With the SNMP agent, the network administrator can logon the switch to
monitor, configure and control each port’s activity in a
friendly way. The overall network management is enhanced and the network
efficiency is also improved to accommodate high bandwidth applications. In
addition, the switch features comprehensive and useful function such as DHCP
Option 82, QoS (Quality of Service), Spanning Tree, VLAN, Port Trunking,
Bandwidth Control, Port Security, SNMP/RMON and IGMP Snooping capability via
the intelligent software. It is suitable for both metro-LAN and office

· Support DHCP option 82
QoS with four priority
The QoS(Quality Of Service) Control List (QCL) 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 vip port, 802.1p priority
tag, DiffServ and/or IP TOS, IPv4 and UDP/TCP application traffics. 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.
It is based on ACL function to classify the ingress traffic to do port copy.
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 is
blocked. Traffic can only be sent from isolated group to non-isolated group.
Mac-based 802.3ad 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
2 dual media ports for flexible fiber connection
2-Port 25,26 dual media ports 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.
The IP network layer uses a four-byte address. The Ethernet link layer uses a
six-byte MAC address. Binding these two address types together allows the
transmission of data between the layers. The primary purpose of IP-MAC binding
is to restrict the access to a switch to a number of authorized users. Only the
authorized client can access the Switch’s port by checking the
pair of IP-MAC Addresses and port number with the pre-configured database. If
an unauthorized user tries to access an IP-MAC binding enabled port, the system
will block the access by dropping its packet.
Access Control List (ACL)
The ACLs are divided into EtherTypes. IPv4, ARP protocol, MAC and VLAN
parameters etc. Here we will just go over the standard and extended access
lists for TCP/IP. As you create ACEs for ingress classification, you can assign
a policy for each port, the policy number is 1-8, however, each policy can be
applied to any port. This makes it very easy to determine what type of ACL
policy you will be working with.
