CoS Profile parameters
Name
Name of the CoS profile.
Type
Indicates the type of CoS profile. Possible values are:
z
PCP
z
IP precedence
z
DSCP
Decode DEI
This field is only valid for PCP CoS profiles. If this field is set, the pre-marking color is decoded from the DEI bit (Drop
Eligible Indication). Otherwise, the user defined pre-color is used.
Encode using DEI
This field controls the DEI bit in an S-VLAN tag. If this field is set and the outgoing packet is marked yellow then the DEI
bit is set to 1. Otherwise, the DEI is set to 0.
Reference count (only visible on existing profiles)
The reference count is the number of policies that are currently using this CoS profile.
Mapping table
The mapping table maps the input traffic to a specific class of service. This table has four columns and N rows, where N
depends on the type of the CoS profile. If the CoS profile type is
PCP or IP precedence then N=8. Otherwise, the CoS
profile is a DSCP profile and N=64. Each row in this table represents a mapping entry and each entry has the following
parameters:
PCP/IP precedence/DSCP [IN]
PCP/IP precedence/DSCP input value.
Pre-marking color
The pre-marking color that will be assigned to the input packet that has this PCP/IP precedence/DSCP value.
Green [OUT]
The class of service value that will be used in the outgoing green packets. This value is selected if the result of the
bandwidth regulator assigned to this entry is green or if the pre-marking color is green and no bandwidth regulator is
assigned to this entry.
Yellow [OUT]
The class of service value that will be used in the outgoing yellow packets. This value is selected if the result of the
bandwidth regulator assigned to this entry is yellow or if the pre-marking color is yellow and no bandwidth regulator is
assigned to this entry.
