Spine-Leaf Architecture of MLAG
MLAG takes the benefits of link aggregation and spreads network bandwidth and reliability across a pair of data center switches to deliver system level redundancy as well as network level resiliency.
1+1 Hot-Swappable Power Supplies and 2+2 Smart Fans

The dual power supplies can be replaced without shutting down the system, and the variable-speed fans with front-to-back airflow automatically adjust fan speed to reduce power draw.

MPLS Helps Establish Point-to-point Connections

MPLS enables small and medium-sized operators to create tunnels for their users, which helps build point-to-point connections and achieves intercommunication between user networks.

MLAG Realizes Uninterrupted Services

The switch running MLAG can be upgraded without disrupting MLAG traffic. During the upgrade, another switch in the system takes over traffic forwarding to ensure uninterrupted services.

Support IPv4/IPv6 Dual-Stack to Run IPv4 and IPv6 in Parallel

Dual-stack allows the current hybrid environment encompassing both IPv4 and IPv6, as well as the future migration to IPv6.

Comprehensive Security Policy Protects from Network Threats

With network-level security and stability capabilities like SSH, ACL, AAA, etc., it defends against network threats for enterprises, campus and financial industry.

Flexible Management and Operation
Users can configure, monitor and troubleshoot the device in real-time without having CLI expertise.
Easy of management: Web, CLI, Telnet, SSH
Diverse of monitor and maintain: SNMP, RMON, sFlow
