[j-nsp] [port mirrorong M320]

[Ibariouen Khalid]

Dear community

i have a question regarding port mirroring on juniper router;
I'll be implementing port mirroring on M320 router forever ( I mean the mirroring will stay configured for ever ), this router is handling around 2.5G of traffic ; does the mirroring impact the performance of the router as it is mentioned in some documents ?
I'll appreciate if some can send me a template of a configuration.
Regards/
