Setting up sflow monitoring on switches

[Firefishy]

We should likely setup sFlow monitoring on our switches.

It will allow us quick view of traffic in the event of a DDOS or similar traffic event.

The OOB devices should likely be the sFlow log destination.

Also up for consideration off-by default?

note: Our Juniper EX4300 switches only support sFlow and not NetFlow.

Juniper configuration snapshot:

set forwarding-options sflow sampling-rate 1000
set forwarding-options sflow polling-interval 20
set forwarding-options sflow collector <collector-ip> udp-port <port-number>
