Class of Service Monitoring and Troubleshooting

Table 17 summarizes the command-line interface (CLI) commands you can use to monitor and troubleshoot Class of Service (CoS). In the table, the commands are grouped by functionality. In the remainder of this chapter, they are explained alphabetically.
