Re: Packet Sampling in Cisco and Juniper Gears



Hi Stas

Benoit and all,

Thank you for responses, but it's seen that I failed in my initial question
description.

Yes, Juniper and [high end] Cisco gears are supporting randomly sampled
NetFlow and some other statistics.

But do they support export of the packet samples? I mean random capture and
export of the partial packet snapshots (header+part of payload) in the
manner similar to sFlow?


For this specific question on the high end routers, not right now but foreseen.

Regards, Benoit.

Regards
Stas

Stas,




Do Cisco and Juniper gears support some form of packet sampling?



Yes for Cisco: systematic count based sampling and random count based
sampling.

Regards, Benoit



I had
checked Juniper documentation and it mention packet sampling fro cFlowD
(Netflow) and file dumping , but it is seen to deal only with L3/L4
headers only. Does Cisco and/or Juniper support sFlow or something
similar??

Stas
