Connectivity Solutions

Upgrade Your Network to High Bandwidth and Scalability
Both the aggregation layer and access layer are designed with dual links, which can eliminate bottlenecks and achieve high-speed networks and get reliable performance.

10G Core and Aggregation Switch with 40G Ports
10G ports for access switch or servers, 40G ports for core switches.

Spine-Leaf Architecture of MLAG
MLAG takes the benefits of link aggregation and spreads network bandwidth and reliability across a pair of enterprise switches to deliver system level redundancy as well as network level resiliency.

1+1 Hot-Swappable Power Supplies and 3+1 Redundant 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
Using the same model of switches, providing a distributed and redundant architecture for uninterrupted service upgrades, and fault isolation for minimized impact.

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 Options
Innovative design supports CLI and easy-to-use Web GUI eliminating rip and replace of equipment as network management needs grow
