Description Bernard Cafarelli 2023-05-25 07:30:42 UTC 
Core OVN added support for MAC_Binding entries aging mechanism in bug 2084668 and this is available in OVN 22.12
It is configured with nb parameters:
https://github.com/ovn-org/ovn/blob/1cc77af0859629129f714fb022f69bbf9c4e18cc/ovn-nb.xml#L2599C37-L2604
https://github.com/ovn-org/ovn/blob/1cc77af0859629129f714fb022f69bbf9c4e18cc/ovn-nb.xml#L165-L171

We have seen several cases where the MAC_Binding table grows a lot, and being able to configure this aging feature will be great to have in 17.1

Documentation note: this should come with documentation and/or KCS entry for visibility to users getting impacted by a large MAC_Binding table

Just one note, this is actually available in 22.09, not sure which version of OSP it might correspond to, but you might have it available earlier.
