Hi all,
I am trying to gather some more info on the downside of the older/used
gear. On paper, it looks like anything from an M5 up would be more than
capable of meeting our needs for the next few years.
EOL gear may not be supported by TAC. Just something to keep in mind.
This is really one of the huge sticking points that I'm having a hard time
resolving. I noticed that for example the M20 is supported through 2012,
but I noticed that everyone shys away from the question of getting a
software contract. I'm dying to know if Juniper just doesn't sell
software-only support or doesn't sell for used gear, etc.
Can someone give me the basics on that? I saw one post that mentioned
having the hardware "recertified", but I'm not interested in hardware
support. I just want to legally license/run current software. I assume
that Juniper is not so dense as to push honest people to piracy, right?
Someone's going to buy a recently used M10i from NHR for over $10K and
then have to resort to nefarious methods to "acquire" new code? Help me
understand this...

On the GigE PICs, what is the main difference between the older and newer
versions? I will likely cheap out and go with just 2 or 3 of them and for
the less bandwidth-intensive stuff stick one of them in a GigE switch and do
the "router on a stick" config with VLANs. Any thoughts on this?
Stay away from the very old GE-SX PICs as there were some with bad
firmware. As for the "different" GE PICs, I assume you mean the differences
between the GE-SFP and the GE IQ/IQ2 PICs.
Correct.
The IQ/IQ2 PICs move queing (and other features) to the PIC from the
FPC. If you plan to run vanilla dot1q with very little, if any, CoS the
older GE PICs should be fine. You really see the differences in running
things like VPLS, CCC encaps, tag rewrites and stacks, etc. You should
check out the PIC guide for those chassis to give you a better
understanding of what's supported on each PIC type.
I'm finding the Juniper site a bit easier to navigate than Cisco's, but
I'm also finding that some interesting looking docs have a padlock next to
them. So I'm asking for a little handout here. I've seen the prices on
used IQ and IQ2 PICs and it's more than I can justify at this point.
Down the road when I do need to tinker with fancy stuff I can look at
that. But what about the most basic QoS and shaping? On the GE-SX PICS
can I do a hard rate-limit per vlan or similar? We do some metro ethernet
where each customer comes in on a distinct vlan. Our choices from the
carrier are either 10 or 100Mb/s tails. It would be nice to be able to
sell, say 30Mb/s on a 100Mb/s tail or 5Mb/s on a 10Mb/s tail. Doable with
the GE-SX PICs?

I have worked for small ISP's before, so I can appreciate your cost
concerns, but to be honest I don't think I'd run a revenue producing network
with EOL gear. If you do, be sure to plan ahead and keep some spares on
hand. Hardware failures always happen at the worst times. ;-)
Too late for that. We've been doing it for years. One of the sellers I'm
looking at would be able to get me everything but the ATM card I need and
be within budget. And have two complete routers... Cheaper than a
hardware contract...
Thanks,
Charles
