Description Daniel Alvarez Sanchez 2021-04-09 14:02:29 UTC

In an scenario with VIPs that are balanced at application level (by for example, keepalived) there could be issues at such level which leads to the VIP flapping very frequently.

This will make the app to send the gARPs announcing the location of the new IP address which will trigger updates of MAC_Binding entries very frequently if the ports flap at high rate. The result is that ovn-northd will stay at 100% CPU and ovsdb-server for SB database will be very loaded.

Just like normal switches have, it would be great if OVN could implement some protection mechanism that when such condition is detected, the MAC address is banned from the switch in one or more ports to prevent this situation from happening.

Comment 4 lorenzo bianconi 2021-07-27 12:49:18 UTC

upstream support: http://patchwork.ozlabs.org/project/ovn/cover/cover.1627052896.git.lorenzo.bianconi@redhat.com/

Comment 6 Dan Williams 2022-05-24 17:07:12 UTC

IIRC this support landed in OVN 21.09 mid 2021.

Comment 9 ying xu 2022-06-14 12:39:25 UTC


 as comment8 said, it is included in https://errata.devel.redhat.com/advisory/96200, it's for ovn-2021,
I tried on version ovn-2021-21.12.0-73.el8fdp.x86_64
the command for copp is not the same as that in ovn22.03.
I want to make sure I should verify this bug in ovn22.03 or ovn-2021?

I would suggest to test both of them, it is just a tiny change I guess.

but why the commands are not the same for these two versions?
I think it is not friendly and not compatiable.

Comment 12 ying xu 2022-06-14 15:24:02 UTC

verified on version:
ovn-2021-21.12.0-73.el8fdp.x86_64
ovn22.03-22.03.0-52.el8fdp.x86_64

although there are some differences between the two versions, the test procedure is the same.
