GRP, PRP, and Line Card Memory Overview
Note For a line card to operate, both receive packet memory DIMM sockets and both transmit packet memory
DIMM sockets must be populated. The SDRAM DIMMs installed in a given buffer (either receive or
transmit) must be the same type and size, but receive and transmit buffers can operate with different
memory sizes.
Table 5 lists the available packet memory configuration options for Cisco 12000 Series Router line
cards. Cisco packet memory configuration options consist of four DIMMs of the same type and size (two
DIMMs for the RX socket pair and two DIMMs for the TX socket pair). The actual default and maximum
packet memory configuration options depend on the type of line card. Table 6 on page 15 lists engine
types for each available Cisco 12000 Series Router line card.
