[j-nsp] EX Switch Question

[Paul Stewart]

Thanks - yup, we are just deploying some EX4500 at a customer site and ended
up keeping their EX4200's just for 100 meg ports ;(

Just avoid the 4500 if you need anything less than 1G copper.  The ports on
the 4500 won't negotiate to 10 or 100.  I was told by the sales engineer
that this switch is a "top of rack" switch so it doesn't support anything
less than 1G. 

I found that funny since I have a whole rack of Avaya gear that Avaya
insists must have the switch set to 100/Full.

As you mentioned this could be the problem or showstopper.
We have not yet found an EX platform (tried 2200/3200/4200/4500/8200) which
supported policing on egress (using Firewall filters and policing, never
tried using QoS)

Just tested it on en EX8216 running 10.4R9 "Referenced filter 'test123' can
not be used as policer not supported on egress"

I do not know if this is a hardware or software problem and if it may be
solved in later releases (if software problem). The latest code we run is
11.4R1 on EX2200/3200/4200/4500 and there it is not possible. I kind of
remember it being a hardware problem but i am not sure.

We would have a couple use cases for this feature too so we would be
interested in any findings.

regards
Tobias
