Aquest switch te com a IP i màscara per defecte:
10.90.90.90/8
i com a usuari administrador:
admin
Per a connectar-vos podeu utilitzar IP Aliasing:
$ sudo ifconfig eth0:1 10.0.0.15 netmask 255.0.0.0
Índex del que cal configurar:
System > System Settings:
System > Password Access Control
Es poden especificar fins a 8 ports
Vegeu també Link Aggregation.
TODO: Captura de pantalla
Vegeu també DHCP Screening
Per fer aquesta pràctica, utilitzem 3 switchos.
Canviem la IP del dispositiu. (Sistema --> Parámetros del sistema). Hem posat la 10.90.90.96, la 10.90.90.95 i la 10.90.90.97.
Connectem els switchos de la manera següent:
Aquesta configuració hauria de provocar alguns bucles. Per tal d'evitar-ho, utilitzem els Spanning Tree Protocol (SPT), que és un protocol que comunica tots els switchos i evita els bucles blocant alguns dels ports. Hem d'anar en els switchos a l'apartat Configuración --> Árbol de expansión --> Parámetros globales de STP. En aquest apartat, activem el RSTP.
Amb l'RSTP activat, evitem els bucles. Aquí podem comprovar què fa aquest protocol en els ports.
En aquest cas, tenim la configuració anteriorment esmentada, i podem veure que el switch ha blocat els ports 23 i 21 del switch 1, ja que si enviés paquets per aquests ports, hi hauria conflictes i causaria el bucle.
Anem al Switch History Log per veure com ens surt el port17 que s'ha canviat després de que fes el bucle.
En el meu cas he detectat que això passa al monitoritzar el dispositiu amb Dude. Els ports apareixen filtered:
$ sudo nmap -p 80 10.90.126.134 [sudo] password for sergi: Starting Nmap 5.21 ( http://nmap.org ) at 2013-03-09 07:46 CET Nmap scan report for switchidata01.ebretic.com (10.90.126.134) Host is up (0.016s latency). PORT STATE SERVICE 80/tcp filtered http
En canvi es pot fer pings als dispositius i SNMP. Precisament per SNMP s'identifica el problema:
