Configuring Composite Operations - Avaya W310 User Manual

Each column represents the following:
• No — a number identifying the operation
• Name — a name identifying the operation. Use this name to attach the operation to a
rule.
• CoS — the operation sets the Ethernet IEEE 802.1p CoS field in the packet to the value
listed in this column
• DSCP — the operation sets the DSCP field in the packet to the value listed in this
column
• Trust — determines how to treat packets that have been tagged by the originator or other
network devices. If the composite operation is set to Trust-DSCP, the packet's CoS tag
is set to 0 before the QoS list rules and DSCP map are executed. If the composite
operation is set to CoSX, the DSCP map is ignored, but the QoS list rules are executed
on the Ethernet IEEE 802.1p CoS field. (For example, the composite operation CoS3
changes the CoS field to 3). If the composite operation is set to Trust-DSCP-CoS, the
operation uses the great of the CoS or the DSCP value. If the composite operation is set
to No Change, the operation makes no change to the packet's QoS tags.

Configuring Composite Operations

You can configure additional composite operations for QoS lists. You can also edit
composite operations that you configured. You cannot edit pre-configured composite
operations.
Note: You cannot configure additional composite operations for access control lists, since
all possible composite operations are pre-configured.
To create or edit a composite operation:
1 Enter the context mode of a QoS list.
2 Type the
must be 12 or higher, since numbers 1 through 11 are assigned to pre-configured lists.
3 Use one or more of the following commands to set the parameters of the composite
operation:
—
dscp
ignore the DSCP field, use the argument
—
cos
ignore the CoS field, use the argument
