Shouldn't be a problem.

Depending on the version of Junos make sure you don't have any port mirroring configured, there is a bug where sflow and port mirroring are configured it will crash the switch.  Fixed in recent versions though.

Subject: [j-nsp] sflow on switch

Does anyone know what the performance hit would be on an ex4200 POE switch if you enable the following on all interfaces?  Would there be problems?

  sflow {
        polling-interval 20;
        sample-rate 500;
        interfaces ge-0/0/0.0;
        interfaces ge-0/0/1.0;
