[. . . ] CoS Override will override the previously configured trust state and apply the default port CoS value to all incoming packets. If a port was previously set to trust DSCP, this command overrides the previously configured trust state, and all the incoming CoS values are assigned to default port CoS value. If an incoming packet is tagged, the CoS value of the packet is modified with the default port CoS. Select the corresponding port number and configure the port setting, then click on the button. The field you changed will update the content to save the configuration. Click on to refresh the settings to current value. To make the configuration effective, please go to "Save Configuration" page, then click on . Figure 55. Trust State GigaX Series L2 Managed Switch User's Guide 4. 9. 2 Mapping This page is used to configure CoS (Classification of Service) and DSCP (Differentiated Services Code Point) mapping. · Map CoS to DSCP: each CoS value can map into one of the DSCP value. Users can use the CoS-to-DSCP map to map CoS values in incoming packets to a DSCP value that QoS uses internally to represent the priority of the traffic. · Map DSCP to CoS: each DSCP value can map into one of the CoS value. Users can use the DSCP-to-CoS map to map DSCP values in incoming packets to a CoS value, which is used to select one of the four egress queues.

Mapping 88 GigaX Series L2 Managed Switch User Guide 4. 9. 3 Class Set This configuration page is used to create QoS classes. A class set is a mechanism that you use to isolate a specific traffic flow (or class) from all other traffic. The class set defines the criteria (match mode) used to match a specific traffic flow to further classify it. The criteria can include matching ACL rule in a Filter Set ID or DSCP list. Only one match mode and only one ACL rule for each class set are supported. After a packet is matched against the class-map criteria, it will be further classified through corresponding policy set. The following fields are available: · Class Name: input a class name. · Filter Set ID: if the match mode is `Filter', users must select an existed filter set ID. [. . . ] TFTP Trivial File Transfer Protocol A protocol for file transfers, TFTP is easier to use than File Transfer Protocol (FTP) but not as capable or secure. Trunk Two or more ports are combined as one virtual port, also called as Link Aggregation. TTL Time To Live A field in an IP packet that limits the life span of that packet. Originally meant as a time duration, the TTL is usually represented instead as a maximum hop count; each router that receives a packet decrements this field by one. [. . . ]
