im brand new to cisco, and ive just purchased a catalyst 1900 to start learning on.
im trying to get some switching started, and i cant seem to get things working.
what i did was create an ip address for the switch, which is the same ip address for interface 0/1. interface 0/1 goes to the gateway router and then out to the internet(so that we are clear, switch ip = interface 1 ip). the gateway has a static ip, and i have 5 allocatable statics(sticky ip) after that. so the switch has its own static ip(i made sure to set the ip default-gateway on the cisco switch).
i then set interface 2 ip to a different ip address and then connected that to a linux system with that static ip.
from the linux box, i can successfully ping the switch, the gateway, and anything else with an ip address. but i cant seem to get internet access on this linux box. i can successfully ping, but when i fire up the browser, i get nothing.
any ideas. i really appreciate it. i know theres something that im missing. ive got my book in front of me and ive followed all of the steps, but this stuff is all written for simulations, so its a little different.
From that linux system are you able to ping sucessfully a valid ip address in the Internet? If so, and you can't open a website that uses Domain Name, then check the Linux's IP stack, maybe you forgot to configure the DNS Ip address, the server that will handle the domain names translation to IP address.
from the linux box, i can successfully ping the switch and another computer that has been assigned a static ip that is connected into the gateway switch, not the cisco switch. i can successfully ping the linux box from that computer, so i can successfully send a ping from a windows computer to the gateway switch, to the cisco switch, and then to the linux box.
i cannot ping anything beyond the gateway switch.
any help would be great. i know this has to be a simple problem, sorry.
