Router Performance Upgrades and Model Identification

The compliance information label on the side of the chassis also identifies the Cisco 12000 Series Router by its model number. The model number indicates the router is in the Cisco 12000 Series, the maximum switching capacity the router supports, and the number of line card and RP slots in the chassis.

For example, the Cisco 12006 Router features 30 Gbps switching capacity in a 6-slot, 2.5-Gigabit per slot chassis, whereas the Cisco 12406 Router features

120Gbps switching capacity in a 6-slot, 10-Gigabit per slot chassis. Table A-6lists the Cisco 12006 and Cisco 12406 Routers and provides model comparison information based on chassis slot counts, maximum switching capacity, and switch fabric type.
