Curation Review
- ✔ Pros: Very high density of 400G ports in a compact fixed chassis (up to 64x 400G in 2RU on the 9364D-GX2A); Full-duplex switching capacity up to 51.2 Tbps with 8.35 Bpps forwarding on the largest models; Flexible port breakouts (4x10G, 4x25G, 4x50G, 4x100G, 2x200G) allow one platform to serve mixed-speed fabrics; Wire-rate MACsec on selected ports and AI/ML-ready congestion features (PFC, ECN, AFD); Supports both NX-OS and ACI (spine and leaf) modes with deep L3 routing and segment routing (SR, SRv6); Large forwarding tables on GX2B models (2M IPv4 LPM and host entries) and 120 MB packet buffer
- ✘ Cons: No public Cisco list price; pricing requires a sales contact or partner quote, and the reseller prices found vary widely; Optics and transceivers are sold separately and must be checked against the Cisco optics compatibility matrix, which adds significant cost; High power draw on the 2RU models (typical 1380 W, max 3124 W), so power and cooling planning is needed; No stacking, so fabrics rely on vPC or VXLAN designs that add configuration complexity; Only 2x 1/10G SFP+ ports on every model, so legacy 1G/10G access or uplink needs require breakouts or extra hardware; Full-scale 400G port density is aimed at data center and AI fabric deployments, which makes the platform poorly suited to small enterprise or access-layer use
