1897004 – Advertised link modes not show 2500baseT and 5000baseT

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description beikesea 2020-11-12 03:29:13 UTC

Description of problem:

The 2.5G and 5G link mode not working after upgraded from redhat 8.2 to 8.3.

I found that the ethtool only shows 100baseT/Full, 1000baseT/Full and 10000baseT/Full respectively while the supported link modes support 2500baseT/Full and 5000baseT/Full.

However, the link speed could recover to 5000bastT/Full after executing command "sudo ethtool -s enp2s0f1 autoneg on".

My network card is Dell 10G 2P X550-t Adapter with firmware 19.5.12. The switch is NETGEAR MS510TXPP.


Version-Release number of selected component (if applicable):
ethtool -i enp2s0f1

version: 5.1.0-k-rh8.2.0

Comment 3 Thomas Haller 2021-03-24 10:04:56 UTC

from the provided information it's not clear that you configured autoneg/speed/duplex via NetworkManager.

the profile you share leaves those parameters unset, which means NetworkManger does not touch them.

that means, the ethtool settings depend on what was configured previously. And which component configure that, and why.


Please provide a full level=TRACE log of NetworkManager that shows what happens. Read https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/contrib/fedora/rpm/NetworkManager.conf#n28 for hints about logging.

Thank you.

This should be fixed upstream by commit:

hmm actually we can see
	Advertised link modes:  10000baseT/Full
	                        2500baseT/Full
	                        5000baseT/Full


and we can see this every second upping, is this expected?
