cos remarking
Use this command to remark the receiving CoS priority for a VLAN tunnel
application. Use the no form of this command to set as customer CoS trusted.
cos remarking NEW-COS [C-VID [, | -]]
no cos remarking [C-VID[, | -]]
Default No COS remarking is set. The user/inner cost is trusted at the interface.
Command Mode Interface configuration
Usage Guideline This command is used for UNI port for VLAN tunnel application.
Use the cos remarking command to remark the outer tag priority. As CoS
remarking is applied for VLAN encapsulation, the new CoS value is added into
the outer priority tag. As CoS remarking is applied to VLAN remarking, the new
CoS value is used to remark (replace) the priority tag.
To retain the priority from the receiving packet, use no cos remarking to make
the system replicate or retain the original priority tag value to/as the out-going
priority tag. This is also referred as user/inner COS trusted. The COS tag
replication is only applied to outer priority tag in VLAN encapsulation and the
COS remarking (replacement) is applied for the VLAN remarking.
Syntax Description
NEW-COS Specifies the new COS value to be added into the outer priority tag for VLAN
encapsulation. Alternatively it is used to replace the priority tag for VLAN
remarking. The available value is 0~7.
C-VID [, | -] (Optional) Specifies the receiving packet with the inner VLAN (customer VLAN
ID, CVID) in this list it will use the new COS value and it will be added into the
outer priority tag (in VLAN encapsulation) or is used to replace the priority tag (in
VLAN remarking).
If C-VID[,|] is not specified for the no cos remarking command, then the ingress
port will trust the user's priority tag and replicate/retain the priority tag except
those customers' VLANs that have been set by cos remarking NEW-COS C-
VID [, | -] command.
If C-VID[,|] is not specified for the cos remarking NEW-COS command, then
the ingress port will remark the user's priority tag and remark/replace the priority
tag except those customers' VLANs that have been set by cos remarking NEW-
COS C-VID [, | -] (cos remarking NEW-COS command is not set at the
interface).
The available values are 1~4094 and only the C-VID has been defined in VLAN
encapsulation or VLAN remarking pair that can be accepted by this command.
That is, the VLAN encapsulation or VLAN remarking pair must be defined, before
the CoS remarking policy is changed.
