C9400X-SUP-2 Description
C9400X-SUP-2—known as the Catalyst 9400X Supervisor 2—delivers 240 Gbps per slot and a 2.4 Tbps fabric to any 9400R chassis, with four onboard 25 G/10 G SFP28 uplinks. Powered by Cisco’s UADP 3.0 ASIC, it provides hardware MACsec-256 encryption, flexible SDM templates, and real-time telemetry via gRPC. Ideal for mid-tier aggregation and distribution, this supervisor balances performance, security, and cost for modern campus networks.

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 |
|
2 |
USB mini Type B Console 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. |
