Does SPAN affect the switch resources or network performance

[engreda22]

Dear ALL ,

Does SPAN (switch port analyzer) affect the switch resources or network performance if it configured in data center switch like 5k or  cat6500 series

appreciate if there an official document from Cisco

Thanks

It all depends on how big network, I suggest to some good reading here :
