Hoi folks,
I took a stab at implementing optical plugin monitoring with SFF8472
compatible interfaces, using DPDK's rte_eth_dev_get_module_eeprom().
Take a look at: https://gerrit.fd.io/r/c/vpp/+/43544
Quick demo:
DBGvpp# show dpdk transceiver ?
show dpdk transceiver show dpdk transceiver
[<interface>] [eeprom] [module] [diag] [verbose]
DBGvpp# show dpdk transceiver TenGigabitEthernet130/0/0 module diag verbose
Interface: TenGigabitEthernet130/0/0
SFF-8472 Module Information:
Identifier: 0x03 (SFP/SFP+/SFP28)
Extended Identifier: 0x04
Connector: 0x07 (LC)
Encoding: 0x06 (64B/66B)
Nominal Bit Rate: 10300 Mbps
Length (SMF): 20 km
Length (SMF): 20000 m
Vendor Name: STARRY
Vendor OUI: 00:1b:21
Vendor Part Number: SFP-10G-LR-20
Vendor Serial Number: 2024082600001
Vendor Revision: A
Wavelength: 8224 nm
Date Code: 240902
Link Codes: 0x00
Options: 0x3a0000
SFF-8472 Diagnostic Monitoring:
Current Values:
Temperature: 40.52 °C
Supply Voltage: 3.3205 V
TX Bias Current: 39.19 mA
TX Average Power: .7712 mW (-1.13 dBm)
RX Average Power: .6724 mW (-1.72 dBm)
Alarm Thresholds:
Temperature High: 90.00 °C, Low: -50.00 °C
Voltage High: 3.7999 V, Low: 2.7999 V
Bias Current High: 110.00 mA, Low: 1.00 mA
TX Power High: 2.5118 mW (4.00 dBm), Low: .1258 mW (-9.00 dBm)
RX Power High: 1.9952 mW (3.00 dBm), Low: .0078 mW (-21.08 dBm)
Warning Thresholds:
Temperature High: 85.00 °C, Low: -40.00 °C
Voltage High: 3.7000 V, Low: 2.9142 V
Bias Current High: 100.00 mA, Low: 2.00 mA
TX Power High: 1.9952 mW (3.00 dBm), Low: .1584 mW (-8.00 dBm)
RX Power High: 1.5848 mW (2.00 dBm), Low: .0100 mW (-20.00 dBm)
I think I got most of it right, and I integrated with
vnet/ethernet/sfp.[ch] and fixed a typo there as well.
If somebody can review and offer feedback, I will continue with SFF8636
for QSFP+/QSFP28 and other multi-channel optics.
groet,
Pim
