[c-nsp] QoS for MetroEthernet

[omar parihuana]

Hello,

I'm facing a strange problem I think that is a QoS configuration, I've tried
some conf without success. The situation is as follows:

Actually I have a 1Mbps Serial link between two remote branchs and one
application in particular: a SQL client/server application that works fine.
(there are other apps but is not relevant now). We've contracted a
MetroEthernet Link at 1Mbps between the same branchs (in order to replace
the current serial link) In each site I put a router after migrate the SQL
app didn't work (it got suck for  a long time). Therefore I decided raise a
GRE tunnel between both sites, applied QoS conf, adjust the tcp mss without
success, all working well (additional apps and voice traffic) but SQL app
didn't work.  I don't know what's happenning with this app, but if you have
faced the same problem, or I need take special considerations for
MetroEthernel Link please your comments will be appreciated.

I paste my conf:
