How to evaluate this exact configuration
WAN connections
WAN connections for C8355-G2: 2 x 10G SFP/SFP+; 2 x 5G mGig RJ-45. Check the carrier handoff and whether any connections share a combo port. Record the required optics or copper connection explicitly rather than buying by family name.
Routing rating
Routing rating for C8355-G2: Up to 38 Gbps forwarding (512-byte packets). Preserve the stated test conditions. Forwarding and encrypted traffic are different workloads; include packet sizes, services and resilience needs in the sizing request.
IPsec rating
IPsec rating for C8355-G2: Up to 20 Gbps (512-byte packets). Compare this figure with the encrypted workload, not only the circuit speed. Confirm the software and licensing needed for the intended deployment.
