Please note that if you enable mls qos on the transit switches the marking
will be removed when traffic cross the trunk. This is becuase you didn't set
the trust on the trunk interfaces and the default level is not to trust any
marking. THerefore, if you enable trust on the transit switches you will need
to enable trust on the trunks.> Date: Thu, 5 Jun 2008 09:04:58 +0300> From:
