Layer 3
Supervisor
Module
The layer 3 Supervisor module requires a faster CPU and more
memory. Also, unlike the layer 2 supervisor, the layer 3 supervisor is
part of the path that some packets take through the system. To
accomplish this, the layer 3 supervisor requires faster data transfer
to and from the switching fabric.
The layer 3 supervisor module features are:
■ PowerPC 750 (RISC) processor
■ Memory: 4 MB Flash, 64 MB DRAM, 128 KB NVRAM, 512
KB cache
■ Multiple memory configurations (refer to Table1-2)
