[c-nsp] 3550 QoS not working as expected

[Tim Devries]

Apologies for revisiting this unresolved issue, but over the weekend I did
an IOS change to IOS C3550 Software (C3550-I5Q3L2-M), Version 12.2(25)SE to
see if that would solve the issue I am experiencing.  However, I am still
seeing traffic spikes up to 5.5mb, and I'm at a loss to explain it.  Anyone
have any ideas?  It seems no matter what I do; traffic will not stay below
the 3Mb threshold.
