H18EDD-2402B Ethernet Aggregation



Overview

H18EDD-2402B is a 24-port Ethernet aggregation and access device produced by Beijing Huahuan Electronics Co., Ltd.On the basis of high-performance L2 switch service, the device provides convenience of maintenance and deployment, multi-service support, carrier-class OAM management, reliable protection mechanism, QoS policy, security mechanism,and other service optimization measures. Meanwhile, it features excellent extensibility and reliability.

H18EDD-2402B is a 1U rack-mounted device,which can aggregate 24 media converters. It provides 2 GE optical ports, 2 GE electrical ports and 24 FX optical ports, which can be configured to UNI or NNI ports flexibly, 1 FE electrical port as out-of-band management port, and RS232as CONSOLE port. H18EDD-2402B supports the latest carrier Ethernet attributes and conforms to IEEE, ITU, and MEF standards. The carrier-class OAM has enhanced network management capacity and meets the operator’s requirements for comprehensive and powerful capacity of monitoring and management. QoS function has extended the scope of carrier Ethernet, applying it to real-time service,i.e. voice and video. S-VLAN ID is used to implement VLAN extensibility and provides service for hundreds of enterprise users and hundreds of thousands of individual users.

Features

l FX optical ports support auto-negotiation mode and 100M full-duplex manual mode; GE optical and electrical ports support auto-negotiation mode and 1000M/100M full-duplex manual mode, as well as AUTO-MDIX, i.e. automatically identify crossover or straight-through networkcables.

l IEEE802.1Q VLAN, IEEE802.1ad VLAN (at most 4094 VLAN entries).

l Carrier-class OAM management including EFM (Ethernetin the First Mile), CFM (Connectivity Fault Management) and SLA (Service LevelAgreement).

l STP/RSTP/MSTP (Spanning Tree Protocol/ RapidSpanning Tree Protocol/ Multiple Spanning Tree Protocol).

l Link aggregation (manual LAG and static LACP(Link Aggregation Control Protocol)).

l QoS function based on port speed limit, portmirror, priority trust, flow classification, flow policy, priority mapping, andqueue scheduling and so on.

l Interface protection.

l Jumbo frame setting (maximum 9720 bytes).

l Flow control.

l LFP (Link Fault Pass).

l DDM (Digital Diagnosis Monitoring).

l MAC Address forwarding control.

l IEEE 802.1X authentication.

l ACL (Access Control List).

l Broadcast storm repression.

l Remote in-band monitoring management.

l Remote power failure alarm.

l NTP (Normal Temperature and Pressure) andRMON (Remote Network Monitoring).

l Upgrade of software through TFTP (TrivialFile Transfer Protocol).

Descriptions

VLAN

IEEE 802.1Q , IEEE802.1ad

STP/RSTP/MSTP

Point to  point mode, implements seconds level link protection  switching to ensure highly reliable network quality

Link  aggregation

3 load sharing algorithms: S-MAC, D-MAC,  S-MAC+D-MAC  , up to 14 aggregation groups

Loopback  detection

Overcomethe influence of loops on network and improve the self-checking, fault  tolerance, and robustness of network.

QoS

Port  limited speed, port mirroring, priority trust, flow class, flow policy,  priority mapping, queue scheduling

Interface  protection

Implementisolation of layer 2 and layer 3 data between interfaces in the interface  protection group.

Flow  control

coordinate two interfaces for normal transmission

DDM

Monitor optical port connection status and quality and  the intelligent optical module’s emission optical power, reception optical  power, temperature, work voltage, laser offset current, and other parameters.

EFM

Complies with IEEE 802.3ah protocol, a link-level Ethernet OAM technology, focuses on link between two directly connected  devices and provides link connectivity check, link fault monitoring, remote  fault notification, and other functions.

CFM

Conduct active fault diagnosis for EVC (Ethernet Virtual  Connection) and reduce network maintenance cost.

SLA

Collect statistics  of response time, network jitter,  delay, packet loss rate, and other network information, monitor the related measures by selecting different  jobs for different applications.

LLDP

Based on IEEE 802.1ab, NMS can quickly master topology and changing  conditions of layer-2 network.

MAC  address forwarding  control

supports up to 16K MAC address table  entries

ACL

Basedon port,  includes IP ACL and MAC ACL.

Strom  suppression

The upper limit of bandwidth is 50Mbps, supports limiting bandwidth of three kinds of broadcast flow: Unknown unicast flow, Unknown multicast flow, Broadcast flow.

LFP

Link  Fault Pass, avoid flow loss when uplink fault cannot be  sensed by the lower layer devices.

RMON

Remote Network Monitoring, realizes functions of statistics and alarm, monitor the remote device more actively and  effectively than SNMP, making network administrators can track failures  occurring to the network, segment and device more quickly.

DHCP

Dynamic Host Configuration Protocol, client/server model, realize dynamic configuration of things like IP  address.

NTP

Network Time Protocol, a time synchronization protocol defined by  RFC1305, used for the time synchronization between distributed time server  and client.
