Cisco Systems CISCO7201 Manual De Usuario

Cache memory

The processor system has two levels of cache: primary and secondary cache that are internal to the 
microprocessor with secondary unified cache for data and instruction. 

Four Gigabit Ethernet interfaces (six ports: four SFP [optical] and two RJ-45s [copper]). Only four 
ports are available at the same time.

One Fast Ethernet Management port

A CompactFlash Disk for storing the default Cisco IOS software image

Auxiliary port with full data terminal equipment (DTE) functionality 

Console port with full data communications equipment (DCE) functionality

Boot ROM for storing sufficient code for booting the Cisco IOS software 

Flash memory for storing the boot helper (boot loader) image

NVRAM for storing the system configuration and environmental monitoring logs. NVRAM uses 
lithium batteries to maintain its contents when disconnected from power.

Two environmental sensors for monitoring the internal temperature of the chassis

The Cisco 7201 processor system performs the following system management functions:

Sending and receiving routing protocol updates

Managing tables, caches, and buffers

Monitoring interface and environmental status

Providing Simple Network Management Protocol (SNMP) management through the console and 
Telnet interface

Accounting for and switching of data traffic 

Booting and reloading images

Managing the port adapter (including recognition and initialization during online insertion and 
removal)

The Cisco 7201 router supports multiprotocol, multimedia routing and bridging with a wide variety of 
protocols and port adapters.
