C9400X-SUP-2XL Description

C9400X-SUP-2XL
C9400X-SUP-2XL also known as the Catalyst 9400X Supervisor 2XL—supercharges any 9400R chassis with 480 Gbps per slot, a 9.6 Tbps switching fabric and integrated 100 G/40 G plus 25 G uplinks. Powered by Cisco’s UADP 3.0sec ASIC, this engine doubles route and ACL scale, delivers MACsec-256 and full-rate 100 G IPsec encryption, and streams real-time telemetry for intent-based networks. Alternate keywords: C9400X SUP 2XL, 9400X-2XL supervisor, Catalyst 9400X 100 G engine.

“Double Extra Large” performance tier

Doubles per-slot & fabric bandwidth vs. 1XL-Y; adds 100 G uplinks, UADP 3.0sec ASIC

Key Features

True non-blocking performance

480 Gbps of fabric per slot yields a flat 1 : 1 line-rate with mGig, 10 G, 25 G and even 100 G line cards, eliminating hidden choke-points during peak Wi-Fi 6/6E or large file transfers

Eight native high-speed uplinks

four QSFP28 ports supply 100 G/40 G backbone links while four SFP28 ports cater to 25 G/10 G aggregation, leaving every line-card slot free for user traffic and simplifying cabling

Hardware-based security at scale

built-in MACsec-256 on every port plus ASIC-level 100 G IPsec tunnels satisfy PCI-DSS, HIPAA and GDPR without external encryptors, ensuring compliance with zero throughput loss

Programmable & observable

UADP 3.0sec supports model-driven telemetry (gRPC), on-box Python, NETCONF/RESTCONF APIs and flexible SDM templates, giving NetOps teams real-time visibility and automation hooks

Carrier-class resiliency

dual-supervisor SSO/NSF fail-over (< 200 ms) and in-service software upgrades keep critical services online during maintenance, ideal for hospitals, airports and trading floors

Investment protection & capacity head-room

double the FIB/ACL scale over earlier engines and support for up to 384 line-rate mGig or 36 line-rate 100 G ports let networks grow for a decade without forklift upgrades

Applications Scenarios

High-density Wi-Fi 6/6E campus cores

480 G/slot fabric keeps bursty mGig switch uplinks non-blocking; MACsec secures east-west traffic

Secure enterprise WAN / hybrid-cloud

Wire-rate 100 G IPsec tunnels integrate encryption without extra appliances, reducing latency and TCO

Smart-building & IoT aggregation

Combines 90 W UPOE+ line-cards with SDA micro-segmentation and real-time telemetry for device-level insights

10/100/1000 Ethernet Management Port (RJ-45 connector)

The Ethernet management port is a Layer 3 host port to which you can connect a PC. By default, the Ethernet management port is enabled. You can use the Ethernet management port instead of the switch console port for network management. This port is not active while the switch is operating normally.Note When connecting a PC to the Ethernet management port, you must assign an IP address.See Ethernet Management Port

4

Console port (RJ-45 connector)

This is an RS-232 serial or console port for system management.See Console Ports

5

RESET switch (recessed)

The RESET switch is used to reset and restart the switch.Note The reset switch is recessed into the front panel. Use a paper clip or a small, pointed object to press the RESET switch.

6

10-GigabitEthernet (GE) or 25-GE uplink ports

The supervisor module has four 10-GE or 25-GE uplink ports.These ports require SFP+ transceivers for 10-GE operation, and SFP28 transceivers for 25-GE operation.The ports are numbered 1 to 4.See Uplink Ports

7

RFID

Supervisor module Radio Frequency Identifier (RFID).Has a built-in, front-facing, non-removable, passive RFID tag that uses Ultra High Frequency (UHF) RFID technology and requires an RFID reader with compatible software. For more information, see Radio Frequency Identification (RFID) on Cisco Catalyst 9000 Family Switches.

What is “Line-rate” and 1 : 1?

Term

Definition

Design Impact

Line-rate

Fabric bandwidth equals the sum of all port speeds.

Zero internal bottlenecks – every port can run at full speed.

Oversubscription

Fabric bandwidth less than total port speed. Expressed as 2 : 1, 4 : 1…

Occasional congestion if many ports burst at once.

1 : 1

No oversubscription (pure line-rate).

Ideal for high-density Wi-Fi 6/6E, 100 G aggregation, low-latency apps.
