• Bottom row ports: Even-numbered (Ethernet 2/2, 2/4, 2/6, 2/8 for slot NM-2)
  Port pairs: 1&2, 3&4, 5&6, 7&8; each pair controlled by dedicated bypass status LED indicatorCisco

Multi-Rate Transceiver Compatibility

1. 25G Ethernet: SFP28 SR, LR, CWDM4 optical transceivers
2. 10G Ethernet: Standard SFP+ SR, LR, ER optical transceivers
3. 1G Ethernet: Standard SFP SX, LX, LH optical transceivers
   Only Cisco-certified optical transceivers enable full hardware security offloading functions.

Native Hardware Fail-to-Wire (FTW) Bypass Feature

• Automatic traffic forwarding between paired ports upon chassis power loss, critical system crash, or security software failure
• Bypass operation runs purely at Layer 1 without CPU or firmware intervention, eliminating total network outage risks for inline security deployments
• Dedicated per-pair bypass LED lights to display real-time bypass operational state for rapid fault diagnosis

4. Performance & Electrical Specifications

Bandwidth & Throughput Metrics

• Non-blocking full-duplex total module aggregate bandwidth: 200 Gbps bidirectional
• Hardware-accelerated NGFW/IPS threat inspection throughput: Up to 175 Gbps with full Snort 3 IPS, AVC application visibility, AMP malware protection, and URL filtering enabled
• TLS 1.3 decryption capacity: Up to 45,000 sessions per second
• Maximum VXLAN tunnel capacity: 1.2 million tunnels for cloud virtual workload segmentation

Latency & Packet Buffer

• Port-to-port forwarding latency under bypass mode: <1.2 μs
• Full inspection latency (IPS + IPsec AES-256 encryption active): <120 μs
• 256MB shared dynamic allocation packet buffer to eliminate packet drops during high-traffic microbursts, validated under RFC 9000 QUIC protocol stress testing

Power Consumption

Environmental Operating Parameters

• Operating temperature range: 0°C to 40°C (32°F – 104°F); throughput performance derates 1% per °C above 35°C

3. Line-Rate Encryption Offload: Hardware-accelerated AES-256-GCM IPsec VPN encryption/decryption, plus MACsec 256-AEAD link encryption running at full port line rate
4. Encrypted Traffic Analytics (ETA): Built-in acceleration for TLS 1.0/1.1/1.2/1.3 encrypted traffic inspection without full packet decryption, meeting HIPAA, PCI-DSS compliance requirements
5. Comprehensive Traffic Inspection Acceleration: ASIC offloading for Snort 3 IPS deep packet inspection, AVC full application identification, NetFlow v9 traffic sampling, and QoS traffic queuing
6. Multi-Context Virtual Firewall Support: Fully compatible with multi-context security virtualization to isolate independent tenant network traffic for managed security service providers
7. Real-Time Status LED Indicators: Per-port link/activity LED indicators plus dedicated bypass pair status LEDs for intuitive real-time hardware fault troubleshooting

6. Typical Enterprise & Service Provider Deployment Use Cases

1. Data Center Inline Workload Microsegmentation: Deploy inline between leaf/spine data center switches to enforce granular security policies for virtual machine, Kubernetes, and ACI/NSX cloud workloads, with hardware bypass to avoid critical data center connectivity outages
2. High-Speed Internet Edge Security Aggregation: Consolidate multi-gigabit ISP fiber uplinks on 25G ports for unified internet perimeter threat defense
