“CARACTERISTICAS PRINCIPALES DEL ROUTER CISCO 2501”
17 DE SEPTIEMBRE DE 2007
Cisco 2501 Principales Características
• Ruteo multiprotocolo entre WANs y LANs.
• Un puerto Ethernet (salida AUI), dos puertos seriales sincrónicos de alta velocidad, un puerto consola y un puerto auxiliar asincrónico de baja velocidad.
• La familia de productos 2500 permite a los usuarios ruteos a través de líneas T1/E1.
• Procesador de 25 MHz, memoria flash de 8 MB y DRAM de 4 MB upgrades hasta 16 MB.
• Protocolos Seriales Sincrónicos: PPP, HDLC, LAPB.
• Servicios Sincrónicos Seriales WAN: Frame Relay, X.25.
Componentes
RAM/DRAM (volátil)
tablas de enrutamiento, caché ARP
script de configuración activo (running-config ) del router
buffering de paquetes (RAM compartida) y cola de espera de paquetes
memoria temporal y/o de trabajo para el archivo de configuración; imagen del IOS mientras el router está encendido (intérprete de comandos, EXEC)
NVRAM (no volátil)
FLASH (no volátil, ROM borrable y reprogramable)
imagen del sistema operativo Cisco IOS
actualizar su software no implica cambio de hardware
puede almacenar varias versiones del IOS
ROM
programa de diagnósticos de encendido
programa de arranque (bootstrap )
actualizar su software requiere cambio hardware
Interfaces
Procesador motorola de 25 Mhz
1 puerto Ethernert
salida AUI
conector DB-15
2 puertos seriales
1 puerto de consola y 1 auxiliar
1 Generador de frecuencia principal
