Bug ID: 207056
Summary: Changing the MAC address on the lagg interface doesn't
get retained after lagg port delete operation.
Product: Base System
Version: 11.0-CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: gopu.0...@gmail.com
Changing the MAC address on the lagg interface does not get retained after lagg
port delete operation.
How to reproduce:
-> Create a lagg interface
-> Add 2 ports to a lagg interface
-> Set the NEW MAC address on the lagg interface, which in-turn change the MAC
of the 2 physical ports.
-> Remove a lagg port from the lagg interface. (It should be the first
interface of LAGG / Master port)
Buggy part:
-> The NEWLY ADDED MAC address will be lost, the lagg interface will have the
other members physical interface MAC interface.
Fix Proposal:
-> At first place, why the MAC change is allowed on the lagg interface.
-> If allowed then the MAC shall be the generic MAC, that shall not be affinity
to a phyiscal port. Hence add / delete port operations on the lagg interface
should not affect the lagg interface MAC address (Unless all the ports were
deleted).
