We just put in the replacement M10 and are waiting for the traffic to go above
130 Mbps on the gigabit. Unfortunatelly saturday mornings are very slow going,
so we'll have to wait some time. The box is new, but the gigabit ethernet PIC
stayed the same. Unfortunatelly I found out the hard way that this M10 only
has the non-enhanced FEB. It's very badly documented, I only noticed because
the previously working configuration produced this:

blaz at maribor3> show interfaces queue ge-0/0/0
Queue statistics are not applicable to this interface.

So I started investigating and found out that the M10 has the non-E FEB (it
was bought used). Curiously enough, it accepted all the CoS commands from the
previous configuration which included queue priorities and DSCP marking, both
of which are unsupported on the non-E FEB according to www.juniper.net.
Even weirder, "show interface extensive" shows this:

...
    CoS transmit queue             Bandwidth           Buffer Priority   Limit
                              %          bps   %        bytes
    0 data                   55    550000000  55            0      low    none
    1 voice                  20    200000000  20            0     high    none
    2 vpn                    20    200000000  20            0      low    none
    3 network                 5     50000000   5            0     high    none
...

Look at the Priority column. This is what I have configured. But why is it
displayed, if the hardware does not support it? Anybody have a spare
FEB-M10-E-S that they're willing to trade for a FEB-M10-S? :-(
