I have been eval'ing an EX3200 for use as a small datacenter
distribution switch. The idea was to have a routed uplink to a bigger
router and routed VLANs to handoff to customers, using the EX as a
cheap router with a bunch of gig-e ports.
It appears that the switch doesn't consistently count traffic on the
RVI interfaces -- in a test enivronment with a routed VLAN uplink
and a separate routed VLAN to a customer, one of the RVIs counts
transit traffic while the other counts traffic to the local IP only
(IP actually on the switch interface).
So I can send a few Mbit/s through the EX and the "uplink" vlan will
count the traffic but the "customer" vlan sits near 0 bytes/packets.
Not very useful for billing customers! (Collecting data on physical
ports works until you have a customer with 2 ports and you don't
want to bill for local switched traffic, or if you are running a vlan
trunk to another L2 switch and need to count traffic per-vlan).
I've yet to get my hands on an EX to eval (we mostly run M series) but I
would assume you could apply firewall filters for input/output to the
RVI with a term that just has "accept" in it and then pull the counters
for those via SNMP?
