[SOLVED] Alternative to ethtool

Ankita_kulkarni · 03-30-2022, 07:05 AM

Hi,
I want to know Ring parameters for eth0:
I used ethool -g eth0 to get the stat, getting below error.

Quote:

$ ethtool -g eth0
Ring parameters for eth0:
Cannot get device ring settings: Operation not supported

is there any other way to check Ring parameters for eth0:?

Thanks

You didn't run the command as root/sudo. Try that.

Your original post showed you were not running as root/sudo. Saying "not working" doesn't tell us anything new...what exactly did you type in, and what exactly was the result? And on what version/distro of Linux? Because that command works fine for me, and will ONLY run as root.

Please find details below:
1. Gentoo Distro (RPI4)
2. Command: ethtool -g eth0 (root -user)
3. result:
Ring parameters for eth0:
Cannot get device ring settings: Operation not supported

Thanks

So you're running Gentoo (don't know the version) on a Raspberry Pi. Have you looked at the hardware specs to see if the actual device supports that? And is the eth0 device the *ACTUAL* name of the device, or an alias??? Physical interfaces are things like BPEthxxx and ethxxxx, and these are the only ones for which you can actually query/change ring parameters.

Read the "Question Guidelines" and "How to ask a smart question" links.

hey, try doing this

The RX ring buffer size can be examined with the ethtool -g command. The default RX Ring size is 256 (the maximum is 4096). User can increase this with the ethtool -G command. Monitor the ifconfig output to see if the RX drops stop.

Did you bother to read the post?? That is exactly what they ARE doing. Second post of yours that appears to not read/understand the topic or address the question. Is there a point?
