Subject: [PATCH ovn 2/4] northd: Log all dynamic address assignments
|
|
|
bbaaef |
|
|
|
bbaaef |
This patch adds INFO level log messages for all dynamic address
|
|
|
bbaaef |
assignments (MAC, IPv4, IPv6). While debugging some issues in
|
|
|
bbaaef |
ovn-kubernetes, I found it would be helpful to see ovn-northd's view
|
|
|
bbaaef |
of what addresses were assigned where and when from its perspective.
