Re: [j-nsp] flow sampling: what packets are chosen?

2013-07-24 Thread Phil Sykes
The sampling is more random - the probability of an individual packet being sampled is 1/1000, but it's not exactly every 1000th packet, and every linecard has an independent sampling engine. A caveat on sample rate - some Juniper hardware (e.g. T-Series FPC3, MX960 DPC) will silently round that

Depending on the hardware platform, it may not be supported (e.g. MX3D/Trio ignores it). On Sun, Feb 24, 2013 at 4:45 PM, Justin M. Streiner wrote: > On Sun, 24 Feb 2013, Piotr wrote: > > I'd like ask about this options, I made some test sampling with >> nfdump+nfsen and i don't see the differ

services firewall would provide a useful stopgap security solution. JUNOS AS firewall is much more painful to configure than ScreenOS today: the ScreenOS web-based management is good for a non-specialist to configure firewall rulesets. Regards, Phil Sykes Technical ConsultantJNCIE-M #22
