https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270083 Marek Zarychta <zarychtam@plan-b.pwste.edu.pl> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |net@FreeBSD.org --- Comment #1 from Marek Zarychta <zarychtam@plan-b.pwste.edu.pl> --- Unfortunately, the removal of code doing re-announcements on the basis of packet counter, according to RFC 3954, is forbidden[1], so maybe our respectable programmers can fix it.=20 [1] 3. On a regular basis, the Exporter MUST send all the Template Records and Options Template Records to refresh the Collector. Template IDs have a limited lifetime at the Collector and MUST be periodically refreshed. Two approaches are taken to make sure that Templates get refreshed at the Collector: * Every N number of Export Packets. * On a time basis, so every N number of minutes. Both options MUST be configurable by the user on the Exporter. When one of these expiry conditions is met, the Exporter MUST send the Template FlowSet and Options Template. --=20 You are receiving this mail because: You are on the CC list for the bug.=
