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 Dan Williams 2018-12-03 03:05:43 UTC 
Some container use-cases would like to set a static IP but leave the MAC assignment up to OVN.  eg "lsp-set-addresses <port> dynamic 1.2.3.4" or something like that that.

I have tested on the latest version and have some questions,can you please help check them?Thanks!

ovn-nbctl: dynamic 3000::99: Invalid address format. See ovn-nb(5). Hint: An Ethernet address must be listed before an IP address, together as a single argument.


2.I configure the static ipv4 and ipv6 together,but the port can't get dynamic mac address:

correct, static ip + dynamic mac is currently supported just for ipv4

have you configured other_config:subnet? ipv4 static ip should belong to the configured subnet field

yes, you need to provide other_config:subnet

Yes,I have configured both other_config:subnet and other_config:ipv6_prefix,at the first time the dynamic address is not assigned.
But once I change to set dynamic mac and ipv4 static ip only,the address can be assigned:

[root@dell-per730-57 ~]# ovn-nbctl clear Logical-Switch s2 other_config
[root@dell-per730-57 ~]# ovn-nbctl lsp-del lsp1
[root@dell-per730-57 ~]# ovn-nbctl  set Logical-Switch s2 other_config:subnet=192.168.0.0/16
[root@dell-per730-57 ~]# ovn-nbctl set Logical-switch s2 other_config:ipv6_prefix=2003::0
[root@dell-per730-57 ~]#  ovn-nbctl lsp-add s2 lsp1 -- lsp-set-addresses lsp1 "dynamic 192.168.0.99 2003::99"
[root@dell-per730-57 ~]# ovn-nbctl get Logical-Switch-Port lsp1 dynamic_addresses
[]
[root@dell-per730-57 ~]#  ovn-nbctl get Logical-Switch s2 other_config
{"ipv6_prefix"="2003::0", subnet="192.168.0.0/16"}
[root@dell-per730-57 ~]#

[root@dell-per730-57 ~]#  ovn-nbctl lsp-set-addresses lsp1 "dynamic 192.168.0.99"
[root@dell-per730-57 ~]# ovn-nbctl get Logical-Switch-Port lsp1 dynamic_addresses

Could you please try the attached patch?
Comment 8 haidong li 2019-02-21 03:49:07 UTC 
Hi,there is error when I use this patch.Are you using the version  openvswitch-2.9.0-95.el7fdp.src.rpm ?
Since this is a issue,I think we can close this bug as verified since ipv4 static can work now.And I will open another one to track it.
Already submit bz1679386.
