The Toolbox

Time: 1:09:45

ethtool

The name itself tells you what it does. It is an Ethernet Tool. It allows you to modify your Ethernet adapter settings. Something you need to know first is ethtool only works with actual physical ethernet adapters, so things like bond0, and tun0 do not work with ethtool.

First let’s look at what the settings are currently for our ethernet device:

# ethtool eno1
Settings for eno1:
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: 100Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
MDI-X: off
Supports Wake-on: d
Wake-on: d
Link detected: yes

So if we just enter ethtool and a device name, we get all of the current settings for that device.

Next let’s look at the driver information for our device:

# ethtool -i eno1
driver: bnx2
version: 2.2.5
firmware-version: 7.6.15 bc 7.4.0 UMP 1.1.9
bus-info: 0000:05:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no

We then are presented with all of the information about the loaded driver. This is usefull if there are multple possible drivers for your device and you trying to see which one it is using.

So how about some stats on that device:

# ethtool -S eno1
NIC statistics:
rx_bytes: 346607038
rx_error_bytes: 0
tx_bytes: 150108632
tx_error_bytes: 0
rx_ucast_packets: 570365
rx_mcast_packets: 39740
rx_bcast_packets: 655093
tx_ucast_packets: 683763
tx_mcast_packets: 98
tx_bcast_packets: 30
tx_mac_errors: 0
tx_carrier_errors: 0
rx_crc_errors: 0
rx_align_errors: 0
tx_single_collisions: 0
tx_multi_collisions: 0
tx_deferred: 0
tx_excess_collisions: 0
tx_late_collisions: 0
tx_total_collisions: 0
rx_fragments: 0
rx_jabbers: 0
rx_undersize_packets: 0
rx_oversize_packets: 0
rx_64_byte_packets: 345900
rx_65_to_127_byte_packets: 288004
rx_128_to_255_byte_packets: 261730
rx_256_to_511_byte_packets: 16738
rx_512_to_1023_byte_packets: 318819
rx_1024_to_1522_byte_packets: 34007
rx_1523_to_9022_byte_packets: 0
tx_64_byte_packets: 168493
tx_65_to_127_byte_packets: 282696
tx_128_to_255_byte_packets: 155438
tx_256_to_511_byte_packets: 1887
tx_512_to_1023_byte_packets: 31679
tx_1024_to_1522_byte_packets: 43698
tx_1523_to_9022_byte_packets: 0
rx_xon_frames: 0
rx_xoff_frames: 0
tx_xon_frames: 0
tx_xoff_frames: 0
rx_mac_ctrl_frames: 0
rx_filtered_packets: 2466002
rx_ftq_discards: 0
rx_discards: 0
rx_fw_discards: 0

More stats on your device than you can shake a stick at. Well you can actually shake a stick at them if you wanted to, but why would you.

We’ve all been in the situatution where you have mutiple ethernet devices and you not sure which one has been assigned what name. Well you can have ethtool tell you with the -p flag. The command looks like ethtool -p [DEVICE] [N], where [DEVICE] is your device and [N] is the number of seconds you want it to blink for. If you do not put anything for [N] it will blink until you terminate it, handy if you have to walk very far to see which one is blinking.

We can also run tests on the device. Note not all devices allow online or offline testing but most do.

# ethtool -t eno1
The test result is PASS
The test extra info:
register_test (offline) 0
memory_test (offline) 0
loopback_test (offline) 0
nvram_test (online) 0
interrupt_test (online) 0
link_test (online) 0

This will run the selftest, it says wether the device passed and then tells you the results for each test individualy, zero is pass any other number is fail.

You can also use ethtool to make temporary changes to the settings. If after having tested the device with these saettings you want to make them permanent you will need to edit the appropriate configuration file.

Let’s look at an example configuration change:

ethtool -S eth0 speed 1000 duplex full autoneg on

What this is saying, for device eth0 set the speed to 1000Mb per second, full duplex, and allow it to auto negotiate.

There is my very brief rundown of ethtool, for a complete list of what you can do with it please refer to the man page.
