We've got hundreds of them in our network and for the most part they're OK.
-I would *die* for MPLS.
-We have run into backplane /pps limitations on the 12port Trimode (4
uplink) model, with customers doing a lot of traffic that have caused
problems.

Subject: [c-nsp] ME3400
Hi does anyone have experience with ME3400 switches. How are the
performing?
What about the stability
We have about two dozen of these in our network, all models except the 24FX
model. We have no complaints whatsoever about their reliability - some have
been up for almost 2 years. In the entire time we've used them, I believe
we've only had two failure issues pop up that caused a reboot. First was an
issue using BiDi SFPs whereby installing two BiDi SFPs into a ME3400-2CS that
operated on the same wavelength caused the switch to reboot. The second was an
IP SLA bug that's since been resolved.
Our biggest complaint with these boxes is lack of future-proofing. The lack of
10/100/1000 on the 24-port box is a letdown, as is the lack of any IPv6
support. In addition, the QoS features appear robust in the marketing
materials, but for *our purposes*, they are very lacking and highly
restrictive. Check out the output policy map guidelines:
http://www.cisco.com/en/US/docs/switches/metro/me3400/software/release/12.2_46_se/configuration/guide/swqos.html#wp1468424
On the plus side, they do support Multi-VRF (no MPLS), and all L3 protocols.
In addition to this, EEM, IP SLA, REP, Ethernet OAM/CFM, and TDR, which are all
good features for ME equipment.
If you're a startup trying to deploy very basic Metro Ethernet services, this
is a good, solid box. We've since made the decision to switch on a
case-by-case basis from the ME3400s due to the aforementioned problems, but
depending on your deployment plans and service capabilities, I'd recommend this
switch. The 2CS is a GREAT ethernet demarcation device, that will likely be
cheaper than something like an EtherNID, depending on your discount with Cisco.
