Thank you Tim and Chris, But correct me if I'm wrong - those are not quite the same thing.
There's no doubt packets are reaching the box (I have PC connected directly to the switch). The difference between traffic monitoring/mirroring and Ciscos' debug, is that with debug you follow the path a packet takes. Traffic monitoring can be a really helpful first step (as I've said, there virtually no doubt the packets are reaching the RE), but my question is about - what's next? Assumed you see only echo requsts and no replies (by "monitor traffic", for example), is there is a trace option to show why an EX decided it shouldn't answer with reply (from its own address)? בתאריך 28 בנוב' 2016 8:45 PM, "Tim Jackson" <jackson....@gmail.com> כתב: > monitor traffic interface ge-0/0/0 size XXXX no-resolve layer2-headers > extensive > > -- > Tim > > On Mon, Nov 28, 2016 at 12:43 PM, Alex K. <nsp.li...@gmail.com> wrote: > >> Hello everyone, >> >> By any chance - is there an equivalent for Ciscos' "debug ip packet" >> command in Juniper? >> >> I'm fully aware that there is a complete distinction between forwarding >> layer and control layer, in those devices - But, I'm taking specifically >> about traffic TARGETING the box itself. >> >> I'm troubleshooting a strange behavior by Juniper EX line.
