Layer 3
Supervisor
Module
Layer 3 Supervisor module is part of the path that some packets take
through the system.
The 50-Series layer 3 supervisor modules features are:
■
PowerPC 750 (RISC) processor
■
Memory: 4 MB Flash, 64 MB DRAM, 128 KB NVRAM, 512
KB cache
■
Multiple memory configurations (refer to Table 1-1)
■
Real-time clock
■
Out-of-band console: 10/100BASE-T & RS-232
■
RMON support
■
Simple Network Management Protocol (SNMP) support
■
Dot matrix display
■
System management functions and interfaces
■
Routing protocols tables and caches
■
1.5 million packets per second of hardware-based routing for
packets that arrive on layer 2-only media modules
■
Software-based routing for packets that are not routed in
hardware
■
Implementation of layer 3 data forwarding for protocols,
such as AppleTalk, that are not implemented in hardware
Figure 1-2 illustrates a conceptual diagram of the layer 3 supervisor
module’s functions.
