[j-nsp] Switch EX4200 doing broadcast for all ports from multicast traffic

[Giuliano Medalha]

People,

We have 4 x EX4200 (4200-24F and EX4200-48T) running 12.1R3.5 code
connected using Virtual Chassis configuration.

The configuration is very simple with 2 vlans.  VLAN - LAN vlan id 10.

The problem is related to traffic monitor software (wireshark for instance).

When we connect wireshark on any port of the switch we can see every
connection on the netowork ... not only broadcast and multicast traffic.

Its like the switch port is a Hub port ... or the asic is mirroring all
vlan traffic to all ports.

basically RTSP traffic and unicast traffic ... 80, 22, 25, etc ...

The network is very full and the devices are all down ...

Does anyone saw this kind of problem before ?

Is it any kind of bug ?

VIRTUAL CHASSIS requires any special software ?

Thanks a lot,

Giuliano
