C9400X-SUP-2XL Description
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.

2XL |
“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
Application Scenarios
480 G/slot fabric keeps bursty mGig switch uplinks non-blocking; MACsec secures east-west traffic
Wire-rate 100 G IPsec tunnels integrate encryption without extra appliances, reducing latency and TCO
Combines 90 W UPOE+ line-cards with SDA micro-segmentation and real-time telemetry for device-level insights

1 |
USB Type A Host Port |
This USB port is a host port for an external USB disk drive. It supports USB versions 3.0, 2.0, 1.1, and 1.0.See USB Type A Host Port |
|

This USB port can be used as a console port, allowing attachment to PCs that are not equipped with an RS-232 interface.See Console Ports |
|
3 |
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. |
|
8 |
40-GE or 100-GE uplink ports |
The supervisor module has four 40-GE or 100-GE uplink ports.These ports require QSFP transceivers for 40GE operation and QSFP28 transceivers for 100-GE operation.The ports are numbered 5 to 8.Note In the accompanying figure, the ejector lever is not displayed in the redundant supervisor module only for the purpose of displaying the port numbers and LEDs behind it.See Uplink Ports |

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. |
