如何找出networking接口的容量?

我可以通过lshw获得networking接口的容量,但sysfs中的哪个文件是存储了这个信息(即/ sys / class / net / eth0 / device /目录中的哪个文件)?

$ sudo lshw -class network *-network description: Ethernet interface product: 82579LM Gigabit Network Connection vendor: Intel Corporation physical id: 19 bus info: pci@0000:00:19.0 logical name: eth0 version: 04 serial: 3c:97:0e:b4:5c:6a capacity: 1Gbit/s width: 32 bits clock: 33MHz capabilities: pm msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=e1000e driverversion=2.3.2-k firmware=0.13-3 latency=0 link=no multicast=yes port=twisted pair resources: irq:43 memory:f2500000-f251ffff memory:f253b000-f253bfff ioport:6080(size=32) $ ls /sys/class/net/eth0/device/ broken_parity_status d3cold_allowed enable local_cpus net remove resource0 subsystem_device class device firmware_node modalias numa_node rescan resource1 subsystem_vendor config dma_mask_bits irq msi_bus power reset resource2 uevent consistent_dma_mask_bits driver local_cpulist msi_irqs ptp resource subsystem vendor 

你看错了地方。

看看/sys/class/net/<device>/speed

一般来说,你可以使用诸如strace之类的工具来find它:

 sudo strace -e trace=file -f -s128 lshw -class network 

您可以通过以下方式检查接口容量。

  1. dmesg | grep eth0

  2. mii-tool -v eth0

  3. ethtool eth0

注意:根据您的设备名称更改设备名称。
