How to evaluate this exact configuration
WAN connections
WAN connections for C8235-E-G2: 2 x 1/10GE SFP+; 2 x 2.5GE 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 C8235-E-G2: Up to 19 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 C8235-E-G2: Up to 5 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.
