Description

The Cisco C9400-SUP-1 is the entry-level supervisor engine for Catalyst 9400 Series modular switches, delivering 1.44 Tbps switching fabric and 80 Gbps per slot capacity. Powered by the Cisco UADP 2.0 ASIC, it provides eight 10 Gigabit Ethernet SFP+ uplinks or two 40 Gigabit Ethernet QSFP+ uplinks with MACsec-256 hardware encryption. Designed for secure campus access and distribution deployments, it supports HA with NSF/SSO and redundant supervisor configurations for enterprise-grade reliability.

FAQs

Q: What is the difference between C9400-SUP-1 and C9400-SUP-1XL?
A: The C9400-SUP-1 is the entry-level supervisor with 80 Gbps per slot and supports 8x 10G SFP+ or 2x 40G QSFP+ uplinks. The C9400-SUP-1XL offers the same capacity but with enhanced scalability features. For 25G uplinks, consider the C9400-SUP-1XL-Y, and for 100G uplinks and 240-480 Gbps per slot, the C9400X-SUP-2 or 2XL models are recommended.

Q: Can I mix C9400-SUP-1 with other supervisor models in redundant configurations?
A: Cisco recommends using matching supervisor models for redundancy. While IOS XE may allow mixed configurations, using identical supervisors (e.g., two C9400-SUP-1 modules) ensures compatibility, consistent performance, and seamless failover with NSF/SSO.

Q: Does the C9400-SUP-1 require a separate license for SD-Access or DNA features?
A: Yes, the C9400-SUP-1 requires separate Cisco DNA licenses for advanced features. DNA Essentials enables basic automation and segmentation, while DNA Advantage unlocks full SD-Access, encrypted traffic analytics, and Cisco AI-driven insights. Licenses are sold separately as term subscriptions (3, 5, or 7 years).

Q: Which Catalyst 9400 line cards are supported by the C9400-SUP-1?
A: The C9400-SUP-1 supports all Catalyst 9400 Series line cards, including 48-port Gigabit models (C9400-LC-48U, C9400-LC-48T, C9400-LC-48P), 24-port 10G models (C9400-LC-24XS), and multigigabit modules (C9400-LC-48UX). Consult the official Cisco datasheet for the full compatibility matrix and minimum IOS XE versions.

Q: Can the uplink ports support both 10G and 40G simultaneously?
A: No, the uplink mode is mutually exclusive. You can configure either eight active 10 Gigabit Ethernet SFP+ ports (ports 1-8) or two active 40 Gigabit Ethernet QSFP+ ports (ports 9-10). A hybrid mode (e.g., 4x 10G + 1x 40G) is available but disables the remaining ports. Configuration is done via IOS XE CLI.
