5.2.1 Label parameters explained
Introduction This section will explain in detail the label parameters and their values.The first part
explains the parameters used to set the priority for internal use like mapping to one
of the 16 internal classes. The second part will explain the parameters that need to
be set to enable QoS throughout the entire network.
Classification The classification parameter determines whether the label classification will set the
internal class (used to determine the IPQoS queue).
Defclass The defclass parameter is used to select the DiffServ queue if DiffServ is enabled on
the destination interface on which the data is forwarded. By default 4, being the
best-effort queue.
Classification values Description
ignore If set to "ignore", the label classification will ignore the
existing packet class and will not set or overwrite the
internal class.
overwrite If set to "overwrite", the label classification will set the
packet class based upon the configured class
parameter, regardless of what the existing packet
class value is.
increase If set to "increase", the label classification will only set
the packet class IF the configure class parameter is
higher than the existing packet class value.
Defclass values Description
0..15 The internal class number.
dscp If this value is used the defclass value is set to the
dscp value. The diffserv code point is automatically
mapped to an internal class corresponding to the DSCP
PHB.
default If selected the defclass value is set to the
SpeedTouch™ default value of 4.
