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 Amit Supugade 2016-08-30 19:18:28 UTC 
Description of problem:
lacp team fails when one of the slaves goes down

Version-Release number of selected component (if applicable):
libteam-1.25-2.el7.x86_64
teamd-1.25-2.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Setup port_channel on switch
2. 
teamd -d -t team0 -c '{ "runner" : { "name": "lacp" },  "link_watch" : { "name": "ethtool" } }'
teamdctl team0 port add enp7s0f0
teamdctl team0 port add enp7s0f1
ip link set team0 up
pkill dhclient; sleep 3; dhclient -v team0
ping -c 20 192.168.1.254
ip link set enp7s0f0 down
sleep 10
ping -c 20 192.168.1.254

Actual results:
team fails when one of the slaves goes down

Expected results:
team should be able to ping even when one of the slave goes down

Hi Amit,

I can reproduce this issue on my side now. But after keep pinging remote. we can ping success after about 50s. e.g.

[root@wsfd-netdev50 ~]# sleep 10 ; ping 192.168.100.2

Would you please check if it the same on your side? I will also try to find the root cause.

Thanks

Comment 3 Hangbin Liu 2016-09-01 09:07:11 UTC 
Hi Amit,

What switch you used to config lacp. I use Juniper switch. After set lacp periodic to fast and this issue gone.

Comment 4 Amit Supugade 2016-09-01 14:34:13 UTC 
Hi Hangbin,
As you pointed out, It works fine on Juniper switch and On cisco switch, ping starts working after about 50s. Thanks!

> Hi Hangbin,

Would you please set lacp periodic to fast and try again? As I tested in comment 3. We can ping success immediately after set one slave down, no need wait for 50s.

Thanks
Hangbin
Comment 6 Amit Supugade 2016-09-12 14:02:35 UTC 
Hi Hangbin,
It works fine on both cisco and juniper switch when we set 'lacp rate fast'.
Below is the log. Thanks!
