CloudEngine 6881 series provide high-density 10GE access to help enterprises and carriers build a scalable data center network platform in the cloud computing era. They can also work as core or aggregation switches on campus networks.

Product Characteristics

High-Density Access

• CloudEngine 6881 series provide up to 48 x 10GE ports, allowing for high-density 10GE server access and smoth evolution.
• CloudEngine 6881 series provide up to 6 x 100GE QSFP28 ports. Each QSFP28 port can also be used as one QSFP+ port, providing flexibility in networking. The uplink 40GE/100GE ports can be connected to CloudEngine 1680 CloudEngine 12800 series switches to build a non-blocking network platform.

Inter-device Link Aggregation, High Efficiency and Reliability

• CloudEngine 6881 series support multi-chassis link aggregation group (M-LAG), which enables links of multiple to aggregate into one to implement device-level link backup.
• Switches in an M-LAG system all work in active state to share traffic and back up each other, enhancing system
• Switches in an M-LAG system can be upgraded independently. During the upgrade, other switches in the system take over traffic forwarding to ensure uninterrupted services.
• M-LAG supports dual-homing to Ethernet, VXLAN, and IP networks, allowing for flexible networking.

Virtualized Hardware Gateway, Enabling Quick Deployment

• CloudEngine 6881 series can connect to a cloud platform through open APIs, facilitating the unified management of virtual and physical networks.
• CloudEngine 6881 series can work with the industry's mainstream virtualization platforms. The virtualization function protects investments by ensuring services can be deployed quickly without requiring network changes.
• The hardware gateway deployment enables fast service deployment without changing the customer network, providing investment protection.
• CloudEngine 6881 series support Border Gateway Protocol - Ethernet VPN (BGP-EVPN), which can run as the VXLAN control plane to simplify VXLAN configuration within and between data centers.

Standard Interfaces, Enabling Openness and Interoperability

• CloudEngine 6881 series support NETCONF and can work with Huawei iMaster NCE-Fabric.
• CloudEngine 6881 series support Ansible-based automatic configuration and open-source module release, expanding network functions and simplifying device management and maintenance.
• CloudEngine 6881 series can be integrated into mainstream SDN and cloud computing platforms flexibly and quickly.

ZTP, Implementing Automatic O&M

• CloudEngine 6881 series support Zero Touch Provisioning (ZTP). ZTP enables the CloudEngine 6881 series to automatically obtain and load version files from a USB flash drive or file server, freeing network engineers from onsite configuration and deployment. ZTP reduces labor costs and improves device deployment efficiency.
• ZTP provides built-in scripts through open APIs. Data center personnel can use a programming language they are familiar with, such as Python, to centrally configure network devices.
• ZTP decouples the configuration time of new devices from the device quantity and area distribution, which improves service provisioning efficiency.

FabricInsight-based Intelligent O&M

• The CloudEngine 6881 provides telemetry technology to collect device data in real time and send the data to Huawei data center network analyzer iMaster NCE-FabricInsight. The iMaster NCE-FabricInsight analyzes network data based on the intelligent fault identification algorithm, accurately displays the real-time network status, effectively demarcates and locates faults in a timely manner, and identifies network problems that affect user experience, accurately guaranteeing user experience.

iMaster NCE-based Simplified Network Deployment

• CloudEngine 6881 series switches can interconnect with iMaster NCE-Fabric through standard protocols such as NetConf and SNMP to implement network automatic management and control, providing more efficient and intelligent operation methods, simplifying network management, and reducing the OPEX.

FabricInsight-based Intelligent O&M

• Huawei's Packet Conservation Algorithm for Internet (iPCA) technology implements accurate per-hop packet loss, delay, and jitter detection for real service flows, locating network faults in real time.
• CloudEngine 6881 series proactively perform path detection over the entire network, periodically checking sample flows to determine the connectivity of all paths on the network and locates fault points, providing real-time network health information.
• CloudEngine 6881 series support visualization of all flows and congestion, improving service experience.

Flexible Airflow Design, Improving Energy Efficiency

Flexible front-to-back/back-to-front airflow design

• CloudEngine 6881 series use a strict front-to-back/back-to-front airflow design that isolates cold air channels from hot air channels. This design improves heat dissipation efficiency and meets design requirements of data center equipment rooms.
• Air can flow from front to back or back to front depending on the fans and power modules that are used.
• Redundant power modules and fans can be configured to ensure service continuity.

Innovative energy-saving technologies

• CloudEngine 6881 series have innovative energy-saving chips and can measure system power consumption in real time. The fan speed can be adjusted dynamically based on system consumption. These energy-saving technologies reduce O&M costs and contribute to a greener data center.

Clear Indicators, Simplifying Maintenance

Clear indicators

• Port indicators clearly show the port status and port rate. The 100GE port indicators can show the states of all ports derived from the 100GE ports.
• State and stack indicators on both the front and rear panels enable users to maintain the switch from either side.
• CloudEngine 6881 series support remote positioning. Remote positioning indicators enable users to easily identify the switches they want to maintain in an equipment room full of devices.

Simple maintenance

• The management port, fans, and power modules are on the front panel, which facilitates device maintenance.
• Data ports are located at the rear, facing servers. This simplifies cabling.
