Table 207 summarizes the command-line interface (CLI) commands you can use to monitor and troubleshoot flow collection and monitoring services. In the table, the commands are grouped by functionality. In the remainder of this chapter, they are listed strictly in alphabetical order.

Note: Active flow monitoring is supported on the adaptive services interface (sp-fpc/picport) on J Series, M Series, and T Series routers, and on the flow monitoring (mo-fpc/pic/port) interface on the M Series and T Series routers. Flow collection is supported on the flow collector interface (cp-fpc/pic/ /port) on M40e, M160, and M320 routers and on the T Series routers. Passive flow monitoring is supported on the flow monitoring interface (mo-fpc/pic/port) on the M40e, M160, and M320 routers and on the T Series routers. |
