Juniper EX4400 Technical Specs & Architecture
The EX4400 platform is designed for modern access networks that need more than basic Layer 2 switching. With EVPN-VXLAN support, advanced policy, and cloud-based management, EX4400 helps bridge traditional campus designs and fabric-based topologies.
Access ports: 1GbE and multigigabit (1/2.5/5GbE) options depending on model (T, P, MP variants).
Uplinks: High-speed uplink ports (10GbE/25GbE depending on SKU) for connecting to aggregation or core devices.
EVPN-VXLAN support: EVPN-VXLAN capabilities enable fabric-based campus designs and integration with QFX leaf–spine fabrics.
Advanced Layer 2/Layer 3: Rich Junos OS feature set including VLANs, LAGs, OSPF, BGP, VRRP, and IPv6.
Management and telemetry: Integration with Juniper Mist for cloud-based operations, telemetry, service-level insights, and automated troubleshooting.
EX4400 is well suited to environments that want a single hardware platform for traditional access switching today and EVPN-VXLAN campus fabrics tomorrow.
