I Believe there is a bug in version 3.x (tested in v 3.9), while exporting configuration in queues simple if there are any queues with unlimited settings in Burst Limit or Burst threshold or 0 in seconds this is what's gets exported:
add burst-limit=/1536000 burst-threshold=/256000 burst-time=/32s comment="" \
direction=both disabled=no dst-address=0.0.0.0/0 interface=all \
limit-at=256000/256000 max-limit=512000/512000 name="Global Forwarding @ \
ITC - 512K" parent=none priority=5 queue=default/default \
target-addresses=12.52.84.35/32 total-queue=default
As you can see:
burst-limit=/1536000
burst-threshold=/256000
burst-time=/32s
If you copy paste this exported queue simple and paste it into a routeros your gone a have three errors ... I don't know but this might be a bug in the exporting engine.
There is another bug/error in exporting engine:
If you /ip firewall layer7-protocol
then export file=l7p for example and later you copy paste that into another router you will end with a bunch of errors because Mikrotik is confusing symbol \ with the \ contained in the regular expressions of the L7 protocols.
Any comments about this? Am I wrong?
