ethtool is a Linux command for displaying or modifying the Network Interface Controller (NIC) parameters.
Contents
Usage
The command is useful for:
- Identification and diagnosis of Ethernet devices
- Extended Ethernet devices statistics
- Control speed, duplex, auto-negotiation and flow control for Ethernet devices
- Control checksum offload and other hardware offload features
- Control digital media adapter (DMA) ring sizes and interrupt moderation
- Control receive queue selection for multi-queue devices
- Upgrade firmware in flash memory
Example
- Display the current parameters for your
eth0device:
$ ethtool eth0 Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: Twisted Pair PHYAD: 2 Transceiver: internal Auto-negotiation: on MDI-X: on Cannot get wake-on-lan settings: Operation not permitted Current message level: 0x00000007 (7) drv probe link Link detected: yes
- Display Ethernet driver settings:
$ ethtool -i eth0 driver: e1000e version: 2.1.4-k firmware-version: 0.13-3 bus-info: 0000:00:19.0 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes supports-priv-flags: no
- Make your NIC blink for the physical port using
eth0:
$ ethtool -p eth0
This is useful if your ethernet adapter has multiple ports and you are not sure which one has been assigned to eth0.
