You can configure properties of the router chassis, including the clock source, conditions that activate the red and yellow alarm LEDs on the router's craft interface, and SONET/SDH framing and concatenation properties for individual PICs.
To configure router chassis properties, you include statements at the
chassis { alarm { interface-type { alarm-name (red | yellow | ignore); } } filter-check days; fpc slot-number { pic pic-number { framing (sdh | sonet); no-concatenate; } } (source-route | no-source-route); redundancy { routing-engine slot-number (master | backup | disabled); ssb slot-number (always | preferred); } }
This chapter describes the following tasks for configuring the router chassis:
