Enterasys Networks 2E253, 2H253, 2H252, 2H258 Displaying the Current PID/Classification Assignments

Priority Classification Configuration Screen

The IP TOS Rewrite parameters are set using the Priority Classification screen. The screen enables you to configure the new IP TOS field for any IP frame classification. A selection field is displayed for all supported classification rules. The default value is “NO CHANGE”. You can optionally specify TOS=PID, whereby the precedence sub-field in the TOS field to match the value of the priority in the classification rule. You can also specify a CUSTOM TOS value between 0 and 255. This allows you to specify an IP TOS value for a particular need.

8.6.3Displaying the Current PID/Classification Assignments

To see which ports are set to a particular PID/Classification (Classification Rule), the Protocol Port Configuration screen must be displayed.

To access the Protocol Port Configuration, proceed as follows:

1.Use the arrow keys to step to the line with the Classification Rule of interest.

2.Press ENTER. The Protocol Port Configuration screen displays, showing a list of the current ports and those associated with the Classification Rule selected in step 1. These ports are identified on the screen by a YES setting. For more information about the Protocol Port Configuration screen and how to use it, refer to Section 8.7.

8.6.4Assigning a Classification to a PID

NOTE: It is strongly recommended that you read Section 8.6.1 for more information concerning classification before configuring the SmartSwitch device. Incorrect configuration will affect network operation.

To add a Classification Rule, proceed as follows:

1.Use the arrow keys to highlight the PID (priority identification) field.

2.Type in the appropriate priority (0 through 7), where 0 is the lowest priority and 7 is the highest priority. Press ENTER.

3.Use the arrow keys to highlight the Classification field.

4.Press the SPACE bar to step to the appropriate Classification. Table 8-7lists the subclassification associated with each Classification (examples of classifications: Ethernet II Type, 802.3 SAP, IP TOS, IP Protocol Type, etc.).

5.Use the arrow keys to highlight the subclassification field to the immediate right of the Classification field. The name of the field changes depending on the selected Classification, as shown in Table 8-7(examples of subclassification: Ethernet II Type, SSAP/DSAP (802.3), Type of Service, IP Protocol Type, etc.).
