Frequently asked questions
What is the switching capacity and port configuration of the QFX5200-32C-AFO?
The QFX5200-32C-AFO delivers 6.4Tbps bi-directional switching capacity with 2.4Bpps forwarding rate across 32 QSFP28 ports. Each port supports 100GbE natively, or can be configured for 40GbE or 50GbE. Ports support breakout to 4x25GbE or 4x10GbE per port, enabling up to 128 logical 25GbE or 10GbE interfaces. Non-blocking architecture ensures wire-speed forwarding across all ports simultaneously.
What routing protocols and Layer 3 features does the QFX5200-32C-AFO support?
The switch supports BGP, IS-IS, and OSPF routing with MPLS label switching (16,000 labels), MPLS IPv4 L3 VPNs (2,048 with Premium Services License), and GRE tunnels (1,024). It includes BFD for fast failover, uplink failure detection (UFD), and static routing. DHCP v4/v6 relay and VR-aware DHCP are supported. Advanced services licensing enables full BGP and IS-IS functionality for complex fabric designs.
What security features are included in the QFX5200-32C-AFO?
Security features include MACsec AES-256 encryption across all ports, SSH v1/v2 management access, control plane DoS protection, storm control, port error disable with autorecovery, and static ARP support. ACLs support L2/L3/L4 filtering with actions including logging, mirroring, rate policing, and marking. SPAN, RSPAN, and ERSPAN enable traffic monitoring. Junos OS provides comprehensive firewall and access control capabilities.
How does the QFX5200-32C-AFO handle packet buffering and congestion management?
The switch features 16MB of shared packet buffer with intelligent buffer management. It supports Priority Flow Control (PFC) and Data Center Bridging Capability Exchange (DCBX) for lossless Ethernet. QoS includes RFC 2598 Expedited Forwarding, RFC 2697 Single Rate Three Color Marker, and RFC 2698 Two Rate Three Color Marker. Per-port and per-VLAN traffic shaping, rate limiting, and queue management optimize performance under congestion.
What are the power and cooling specifications for the QFX5200-32C-AFO?
The switch operates on 100-240VAC, 50-60Hz input. It features redundant N+1 hot-pluggable fan modules with variable speed control to minimize power consumption. Supports both front-to-back and back-to-front cooling airflow directions for flexible data center deployment. Exact power consumption varies by configuration and transceiver type; refer to Juniper power system documentation for detailed specifications.
Is the QFX5200-32C-AFO suitable for leaf-spine fabric architectures?
Yes, the QFX5200-32C-AFO is optimized for leaf deployments in leaf-spine fabrics. It supports up to 128 link aggregation groups (LAGs) with 64 ports per LAG, enabling multi-path redundancy to spine switches. VLAN support (4,096 VLANs), QinQ, and VLAN translation facilitate multi-tenant isolation. Low latency and high throughput make it ideal for east-west traffic in modern data center architectures.
What operating systems and management interfaces does the QFX5200-32C-AFO support?
