Monitoring the Host Module

You monitor and maintain the M40e and M160 router host module—the Routing Engine and the Miscellaneous Control Subsystem (MCS)—which constructs routing tables, performs system management functions, and generates the SONET/SDH clock signal for SONET/SDH interfaces. (See Table 82.)
