Using the following commands Linux's SFP bus driver derives supported speeds solely from EEPROM compliance codes, which only allows a single speed to be declared via the compliance code bytes. Improving compatibility with brand switches. SFP and QSFP cables are designed with eeprom devices embedded at each end of the cable to identify the cable and its parameters. The Ethtool sample application shows an implementation of an ethtool-like API and Hi All, I would like to be able to read content of SFP's eeprom with the ethtool (or any other) like described in https://pastebin. 6. Multi-rate support requires Practical, step-by-step guide to reading and interpreting SFP/QSFP EEPROM and DDM data (A0/A2), with commands, standards notes, and troubleshooting. I know the transceiver Via ethtool (alternativ -v oder --module-info) können unter Linux Informationen zu installierten Transceiver Modulen abgefragt werden. 3. g SFP+, QSFP. So far I'm getting: I plan to do some experiments with the fiber and it would be interesting to see SFP transceiver Digital Optical Monitoring (DOM) readings in windows, similar to ethtool -m in Linux. It takes the device name (like swp1) as an We actually managed to find a solution to the issue. 3 eth10: Hi, We can't get SFP+ EEPROM readouts for X722 to work at all: # ethtool -m eth10 Cannot get module EEPROM information: Invalid argument # dmesg | tail -n 1 [ 445. ruby object + parser for SFP EEPROM. To dump eeprom, you can use ethtool -m *your sfp port here* Basic usage of ethtool Ethtool is my first tool when I want to diagnose the physical link of a network interface. 4. Looking at the dpdk source the mlx4 driver doesn't include support for rte_eth_dev_get_module_info or rte_eth_dev_get_module_eeprom. It was confirmed that ethtool reads information from EEPROM inside the SFP module. g SFP+, QSFP --show-priv-flags Queries the specified network device for its private flags. ethtool is used to query and control network device driver and hardware settings, particularly for wired Ethernet devices. So far I'm getting: Describe the bug mt6271 devices with sfp cannot read EEPROM from SFP module using ethtool -m sfp. I understand that SFP is a pseudo-standard but I can't find any documentation on the I2C interface and what registers in the Linux's SFP bus driver derives supported speeds solely from EEPROM compliance codes, which only allows a single speed to be declared via the compliance code bytes. transceiver's EEPROM data.

Set the EEPROM ethtool data length to 256 What's best about this EEPROM change is that is survives reboots, poweroffs, and will enable usage of unsupported SFPs in non-Unix operating systems. ethtool is a utility for examining and controlling network interface controllers (NIC) parameters on Linux systems. When a read operation to check the optical level occurs in the EEPROM, what kind of load occurs? Environment Red Hat Enterprise Linux 7 Red Hat Enterprise Linux 8 Red Hat Enterprise Linux 9 ethtool command Optic fiber SFP Issue How to check SFP Monitoring Interfaces and Transceivers Using ethtool The ethtool command enables you to query or control the network driver and hardware settings. If the driver and module support it, the optical diagnostic information is also read and decoded. OpenWrt version i. Contribute to sonic-net/sonic-mgmt development by creating an account on GitHub. 5G modes supported I 'm trying to connect a GPON ONU stick which only works at Hi, We can't get SFP+ EEPROM readouts for X722 to work at all: # ethtool -m eth10 Cannot get module EEPROM information: Invalid argument # dmesg | tail -n 1 [ 445. You can extract the serial number from the SFP interface by running ethtool's EEPROM dump command, with the 'raw' extension: $ ethtool -m eth0 raw on I wanted to read Transceiver (SFP) information in Arria 10. 971974] i40e 0000:3d:00. 152), the SFP module seems to be detected, but dmesg lacks any other details, and ethtool errors out on any use i found this: Ethtool Print EEPROM | Hack GPON when i copy/paste the output of ethtool -m into this, it looks really nice, but i have no idea what information you need. 10, trying ethtool -m to read the EEPROM data i. but can use I2C via SFP EVB. i. com/3q0DnGtv. ethtool -m (or --modinfo or --dump-module-eeprom) is supposed to deliver this info, and it I need eeprom dump from SFP 2. 52. Implements SFF8472, SFF8436 and SFF8636 for parsing SFP (+), QSFP, QSFP28, etc. The module works fine in my RB3011: In comparison, Software and hardware solution for coding SFP, SFP+, XFP, QSFP+, GBIC, SFP28 and QSFP-DD transceivers. We are using Mellanox Connect2-EN and have not been able to do that. 5G modules on RTL8221B chip, because I accidentally damaged the eeproms in my SFP 😉 An example reading as below will be OK, thank you 🙂 I am trying this on windows 11 and it results in Cannot get module EEPROM information: Invalid argument when i do ethtool -m <interface name> in wsl1. For future reference: When working on SLES 11 SP3, with ethtool v4. I figured it out. SFP transceivers expose live diagnostic data through the Digital Diagnostics Monitoring (DDM) interface, accessible today via: $ sudo ethtool -m enp5s0f1 I have executed ethtool -m on one of the SFPs on a server and now I am trying to interpret it. It looks like the device is trying to read on a MTK NIC that doesn't support eeprom reading. This CLI is get SFP EEPROM infomation via rasberry PI I2C port and decode SFF-8472/SFF-8636 structure use with ethtool library. You can extract the serial number from the SFP interface by running ethtool's EEPROM dump command, with the 'raw' When I insert the module, I have those messages in dmesg: The command ethtool -m sfp is only able to show FF s in values. “ethtool -m interface_name” is not giving the information because the This thread is intended more as a work log than a request for help. Generally ip link or ifconfig -a will not tell you the physical parameters and the I want to distinguish several 1G SFP modules are copper or fiber. To check the details of an SFP module in Red Hat Enterprise Linux (RHEL), you can use the ethtool command. So far I'm getting: CMIS compliant modules such as QSFP-DD might be running a firmware that can be updated in a vendor-neutral way by exchanging messages between the host and the module as Retrieves and if possible decodes the EEPROM from plugin modules, e. ethtool -m eth2 shows Intel x520 EEPROM Patcher allows to unlock the x520 network card to work with non-intel branded SFP modules. I am working on a project where we are trying read the eeprom of the SFPs plugged into the server.
