Cisco Systems RJ-45-to-AUX manual Connecting to the Console Port

RMON provides support for the following groups of Token Ring extensions:

∙MAC−Layer Statistics Group—A collection of statistics from the MAC sublayer of the Data Link layer, kept for each Token Ring interface. This group collects information such as the total number of MAC layer packets received and the number of times the port entered a beaconing error state.

∙Promiscuous Statistics Group—A collection of promiscuous statistics kept for non−MAC packets on each Token Ring interface. This group collects information such as the total number of good non−MAC frames received that were directed to a Logical Link Control (LLC) broadcast address.

∙Ring Station Group—A collection of statistics and status information associated with each Token Ring station on the local ring. This group also provides status information for each ring being monitored.

∙Ring Station Order Group—A list of the order of stations on the monitored Token Ring network’s rings.

To see a list of available commands, use the ? command. Table 2.1 provides a list of the ROM command−line interface commands and a brief description of each.

Connecting to the Console Port

To initially configure a switch, you must make a connection to the console port and enter instructions to the switch from this port. The console comes preconfigured on a Cisco device and ready to use. You can access the console port in a number of ways, as shown in Figure 2.2.
