ZXR10 2920/2928/2952 series products are megabit L2+
Ethernet switch, providing gigabit upward Ethernet ports. They
can provide different quantity of & interface-types of Ethernet
port, mainly located at megabit access & converge to provide
fast, efficient, and cost-effective access and convergence
solutions.

Port & insert-card expanding instance that ZXR10
2920/2928/2952 switch series support are as follows:

ZXR10 2920/2928/2952

(V1.0) Access Switch User Manual （Volume I）

 ZXR10 2920:support sixteen 100M & four 1000M ports

 ZXR10 2928: support twenty-four 100M & four 1000M ports

 ZXR10 2952: support forty-four 100M & four 1000M ports

Note:2920 & 2928 support insert-card expand.ZXR10

2920/2928/2952 switch series have the following characters.

Switching Capability

All the ports of ZXR10 2920/2928/2952 megabit switch series
support the layer-2 switching at wire-speed. The filtration and
stream sort transact based on port do not weaken the switching
capability. Ports provide high throughput, packet discarding rate,
time delay and dithering can satisfy the demand of the key
application.

Features

Reliability and characteristics

ZXR10 2920/2928/2952 megabit switch series ensures the link
redundancy backup through STP/RSTP/MSTP. RSTP switching
that is based on IEEE-802.1w ensures the usability of the
network. These switches support the LACP function of 802. 3ad
function, and it supplies the load equalization backup and the
link. Switches support Ethernet ring network mode through
ZESR. High switching capability ensures that the operation do
not be interrupted.

Particular function

The following are the kinds of operation characteristics and
control:

 Use of different modes of VLAN sort. It can be classified by

types of port, protocol, and strategy.

 Provide VPN on layer-2 through QinQ, in addition to

SelectiveQinQ, and supply flexible control ability for optional
outer layer label, which makes it convenient to operate and
scheme.

 Supports the client-end VBAS function, and supplies efficient

orientation technology support for client end.

 Milticast support technology, includes igmp-snooping and

proxy function, fast-leaving characteristic and Multicast-Vlan
Switching (MVS) function & IPTV support.

Chapter 2 System Overview

Security Controls

User Security

Control

Equipment

Level Security

The following are user level security control:

 IEEE 802.1x implements dynamic and port-based security

provides the user ID authentication function and
MAC/IP/VLAN/PORT combines at random, and prevent illegal
user to accessing the network.

 Segregating the ports is helpful to make sure that users can

not monitor or access to other users on the same switch.

 DHCP monitoring prevents spiteful users deceiving the server

and sending spurious address, so it can start protecting IP
source and create a binding table for the IP address of the
user, MAC address, ports and VLAN to prevent user deceiving
or use IP address of other users.

The following are the equipment level security control:

 CPU security control technology can resist DoS attack from

CPU.

 SSH/SNMPv3 protocol supplies network management

security.

 Multilevel security of console can prevent unauthenticated

users changing the switch configuration.

 RADIUS authentication may carry on the common control to

the switchboard.

Network

Security

The following are the network security control:

 ACL based on port or Trunk makes it possible for users to

apply security strategy to the ports of switches or Trunk.

 Binding MAC address and the filtration based on source or

destination supply effective control over the flux based on
address.

 Port MIRROR function is an effective tool for network

management analyses.

QoS Guarantee

Applications of QoS are shown below:

 Standard 802.1p QoS and DSCP field sort label and sort

again based on single group with source and destination IP
address, source and destination MAC address, and TCP/UDP
port number.

 Queue schedule arithmetic, Strict Priority(SP) & combination

schedule.

 Support CAR（Committed Access Rate）function. Manage the

asynchronous upward and downward data stream from end

stage or up link. Input strategy control supplies the
bandwidth control with minimal increment by 64kbps. It can
satisfy the demand of discarding packets, time delay and
time dithering when network congestion occurs, and supply
the congestion avoiding function for the alignment.

Management

Switch management is described with the following statement:

 Supports SNMPv1/v2c/v3 and RMON.

 Supports ZXNM01 uniform network management platform.

 Supports CLI command lines, including Console, Telnet and

SSH to access the switch.

 GUI method supports Web network management.

 Manage through ZGMP group.

Store and

Forward Mode

Functions

ZXR10 2920/2928/2952 adopts Store and Forward mode and
supports layer-2 switching at wire-speed. Full wire-speed
switching is implemented at all ports.

ZXR10 2920/2928/2952 has the following functions:

 Megabit ports support port 10/100/1000M self-adapting and

MDI/MDIX self-adapting.

 Kilomega ports support port 10/100/1000M self-adapting and

MDI/MDIX self-adapting.

 Support 802.3x-compliant flow control (full duplex) and

back-pressure flow control (half duplex).

 (VCT) function and faulty circuit test.

 Support 802.1q-compliant VLAN and private border VLAN.

Maximum number of VLANs can be up to 4094.

 Support VLAN stacks function, and outer label is optional.

 Support GVRP dynamic VLAN.

 MAC addresses self-learning capability. The size of the MAC

Power Module

Control module consists of main processor and external
functional chips to implement applications such as switching
module control & manage for the system. It provides
operational interfaces, such as serial ports and Ethernet
interfaces for data operation and maintenance.

Switching module has Ethernet switching processing chips. Its
primary function is simply switching traffic from multiple devices.
This chip is interlinked with data packet transceiver and can
directly provide hundred megabit or gigabit service interface to
the users.

Interface module is composed of interface boards to accomplish
the external user connection and transceivers packets. The
interface module & switching module are interlinked by standard
interface.

Power module adopts the 220 VAC or -48 VDC for power supply
to offer required power supply for other parts of the system.

 System indicators include power indicator (PWR) and running

indicator (RUN).

f After the system is powered up, the PWR indicator is on

and the RUN indicator is off.

f BootROM starts to load the version. If the version is

unavailable, the states of indicators do not change. If
the version is loaded normally, the RUN indicator flashes
at 1Hz.

f If the power indicator (PWR) is flashing , it indicates that

the switch is the main or standby role of the stack
system. Flashing in the same frequency with RUN shows
it is the main equipment. Flashing in the half frequency
with RUN shows it is the standby equipment.

 32 indicators corresponds to 10/100 Base-T port , each port

with two:one is semiduplex/fullduplex, & the other is link
activation indicator.

fullduplex, is off in the condition of semiduplex. , & is
flashing in the condition of collision.

f Link activation indicator is flashing when the link is

activated.
