https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=291100 --- Comment #2 from Achilles Gaikwad <achillesgaikwad@gmail.com> --- (In reply to Marek Zarychta from comment #1) Thank you for the feedback Marek, >Perhaps this can be dynamic in dynamic a environment? I don't know if it will be accepted or not, but could you please rework your patch to make this value runtime tunable ? Yes, as of today, we can change this value using a `sysctl`. I also agree, users can configure this themselves in a dynamic environment where IP addresses can be recycled. With this change I am hoping that we can provide a better user experience by defaulting to 60s instead of 20m as this would not affect systems negatively. ``` $ sysctl net.link.ether.inet.max_age net.link.ether.inet.max_age: 1200 ``` -- You are receiving this mail because: You are the assignee for the bug.
