[j-nsp] VMX to VMX traffic on ESXi

[serge vautour]

Hello,

Thanks to everyone who replied with suggestions.

I did not have any licenses installed. Oddly enough VMX2 was showing:

user at LabVMX2> show pfe statistics traffic bandwidth
    Configured Bandwidth         : 1000000 bps
    Bandwidth                    : 0 bps
    Average Bandwidth            : 339 bps

This explains why VMX1 could receive traffic from VMX2. VMX1 had:

user at LabVMX1> show pfe statistics traffic bandwidth
    Configured Bandwidth         : 0 bps
    Bandwidth                    : 0 bps
    Average Bandwidth            : 0 bps

This is very strangle considering I created both VMX from the same install
file and they have near identical configs!?!

Anyway I downloaded a 60 trial license from the Juniper web site and
installed on both. Everything is now working as expected.

Thanks,
Serge
