DGS-6604 m cos remarking 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[, | -]] 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 CVID [, | -] 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 NEWCOS 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. Default Command Mode Usage Guideline No COS remarking is set. The user/inner cost is trusted at the interface. Interface configuration 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. CLI Reference Guide 127
