4. Test Data

4.1 Test Scenario

Network Topology: A diagram illustrates the connection between a Cisco C9500-24Y4C switch, an FS QSFP-SR4-40G transceiver, an Intel E810-CQDA2 Network Interface Card (NIC), and an FS RS7260 server via optical fiber.

Interoperability Test Scenario: An image shows a server rack populated with networking equipment, including multiple switches and servers, set up for interoperability testing.

Test Premise:

Confirm the brand, quantity, and placement of the switches to be tested.
Prepare control cables, test software, and optical fiber patch cords. Power on the switches in advance.
Locate the Console port on the switch (typically marked "CON", "IOIOI", or with a computer monitor icon). Connect the switch to a computer using a control cable.
Before connecting the software, verify the connection port in the computer's device manager (Ports COM and LPT).

Test Method:

Use SecureCRT Portable software to establish a quick connection. Configure the settings as follows:

Protocol selection: Serial
Port selection: Match the port identified in the previous step.
Baud rate selection: Match the baud rate of the target switch's port.
Flow control: Do not check this option.
Other configurations can remain at default values.

4.2 Test Result

Test Steps:

Insert the module into the appropriate switch port. Connect TX-RX ends with an optical fiber jumper or MTP self-loop device. Verify connection status. If not connected, check jumper connections or switch port configuration.
Log in to the switch using the test interface, account, and password, then enter privileged mode.
Execute relevant switch commands to view port status (connectivity, connection rate, alarm status), module basic information, and DDM information to ensure requirements are met.

Switch Port Status:

The Cisco IOS XE Software version is 17.12.03. The switch interfaces status shows many ports as 'notconnect'. Ports Hu1/0/25 and Hu1/0/26 are reported as 'connected', 'full' duplex, with '40G QSFP 40G SR4 SFP' speed and type.

NIC Port Status:

The NIC ports (ens2f0np0 and ens2f1np1) support various link modes including 25000baseCR/Full and 100000baseSR4/Full. They operate at 'Speed: 10000Mb/s', 'Duplex: Full', with 'Auto-negotiation: off', and 'Link detected: yes'.

Module Basic Information from Switch:

Port Hu1/0/25: Name: Hu1/0/25, Administrative Speed: 40000, Administrative Duplex: full, Operational Speed: 40000, Operational Duplex: full, Media Type: QSFP 40G SR4 SFP.
Port Hu1/0/26: Name: Hu1/0/26, Administrative Speed: 40000, Administrative Duplex: full, Operational Speed: 40000, Operational Duplex: full, Media Type: QSFP 40G SR4 SFP.

Module Basic Information from NIC:

For the NIC, the module identifier is QSFP+. The transceiver type is 40G Base-SR4, using 850 nm VCSEL technology with a wavelength of 850.000nm. The vendor is FS, with part number QSFP-SR4-40G. Module temperature is around 31.86-32.69°C, voltage is approximately 3.2850-3.3390 V. Laser bias currents are around 6.4-6.5 mA. Transmit optical power is approximately -0.7 to -0.9 dBm. Receive optical power for Channel 1 is around 0.1-0.8 dBm, while Channels 2-4 show very low readings (-40.00 dBm). Various alarm/warning flags are reported as 'Off' or 'On' for bias current, temperature, voltage, and transmit/receive power.

DDM Information:

Detailed Digital Diagnostic Monitoring (DDM) information is provided for ports Hu1/0/25 and Hu1/0/26. This includes temperature, voltage, laser bias current, and transmit/receive optical power readings, along with their respective high/low alarm and warning thresholds. For example, for Hu1/0/25, temperature is 34.6°C, voltage is 3.37V, bias currents are around 6.4-6.5 mA, transmit power is around -0.7 to -0.9 dBm, and receive power is around 0.1 to 0.6 dBm for Channel 1, with very low readings for Channels 2-4.
