[c-nsp] Cisco ME-3400 and queue drops after IOS upgrade

[Robert Hass]

Hi

After IOS upgrade Cisco ME-3400 switch from IOS version 12.2(25)SEG to
version 12.2(44)SE we occuring Output drops on FE ports. Before IOS upgrade
we didn't saw any Output drops on these ports. Maybe previous version of IOS
just didn't show drops in theris output ?

FastEthernet0/5 is up, line protocol is up (connected)
  ...
  Full-duplex, 100Mb/s, media type is 10/100BaseTX
  ...
  Last clearing of "show interface" counters 1d00h
  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 5505
  Queueing strategy: fifo
  Output queue: 0/40 (size/max)

It's first my Catalyst switch smaller than 6500 which showing us Output drops
in 'show interface' output, curios.

BTW. Did anyone already configured some QoS for VoIP at ME-3400
switches ? QoS here is a little different than MLS QoS at 3560/3750...
All our voice/VoIP traffic is marked with Precedence 5.
