QoS Commands
configure diffserv examination code-point qosprofile ports
configure diffserv examination code-point <code_point> qosprofile
<qosprofile> ports [<portlist> | all] {low-drop-probability |
high-drop-probability}
Description
Configures the default ingress Diffserv code points (DSCP) to QoS profile mapping.
Syntax Description
Default
See Table 10.
Usage Guidelines
You can specify up to 64 different code points for each port. Code point values are grouped and
assigned to the default QoS profiles as follows:
The mapping is applied in the ingress direction.
The
low-drop-probability
and
high-drop-probability
keywords are applicable only to SONET
ports. The
low-drop-probability
and
high-drop-probability
keywords are useful in conjunction
code_point Specifies a DiffServ code point (a 6-bit value in the IP-TOS byte in the IP
header).
qosprofile Specifies the QoS profile to which the Diffserv code point is mapped.
portlist Specifies a list of ports or slots and ports. May be in the form 1, 2, 3-5, 2:5,
2:6-2:8.
all Specifies that this applies to all ports on the device.
low-drop-probability Specifies that the DSCP has a low drop-probability level. Supported only for
SONET ports on a PoS module.
high-drop-probability Specifies that the DSCP has a high drop-probability level. Supported only for
SONET ports on a PoS module.
