To assign QOS coefficients for a specific wide IP from the
command line
1. Type the following command to ensure that the configuration files
contain the same information as the memory cache.
3ndc dumpdb
2. Open the wideip.conf file in a text editor (either vi or pico).
3. Locate or add the globals statement. The globals statement should
be at the top of the file.
4. Refer to the example syntax shown in Figure 8.3 to define a wide
IP's QOS equation. Figure 8.3 displays a wide IP definition that
overrides the global QOS equation settings shown in Figure 8.2.
5. Save and close the file.
6. Commit the changes to the configuration by typing:
3ndc reload
