How to configure a Cisco Switch?

[Ithigor]

I have a Cisco Switch "Catalyst 2900 XL" setup ut apparently missed something in the configuration. But, now if I telnet to the switch iot doesn't start a configuration wizard, and there is no help in any of the documentation that cisco sent with it. I have searched there web site and cant find anything that is helpful.

I just want to Telnet back to the switch (which I can do) and change all the settings (Ip, subnet, etc.) and that I cannot figure out. There is also a cluster management tool that lets you get to the switch through the ip address. But that pos disn't work either, it just says "applet not initialized".

Anyone know of a site that can help me out?

Thanks,

Dave

Configuration Wizard?

How are you connected to the switch? A PC connected to the terminal port on the switch using Telnet?

To show your current config use:

show config

-or-

show running-config

You'll need to go into Priveliged exec mode so type:

enable

Prompt should now be Switchname#

from there you will have to go into config mode with

conf t

Prompt should now be Switchname(config)#

To get back to user mode type:

disable

A few config commands:

show ip -> Shows current IP
ip address ip address netmask -> will change the IP address

show interface -> To show your interfaces
set interface interface ip address netmask broadcast address -> to assign an IP address to a switch interface.

I will try and dig out some simple docs for you. There are ways to get the switch to go through its running config, but its not really a wizard as such.

Here is the full Cisco documentation for the 2900XL - Cisco 2900XL

I am connecting with a pc serial port and telnet. I know it isnt really a wizard, but the first time you connect to it, it runs through an initial setup. Now when I go back in, it does nt run it anymore. I have many switch's allready in use. If I use the ip address, normally I can access them through a browser with the cluster management java application. But, when I try to access the latest server, I get the message that topology under construction. So, I imagine I made a m istake in the intial setup, and need to egt back in and start over.

Thanks for your help.

I would go through the "forgotten password" procedure and build a new config. Unplug the switch and hold down the MODE button, then plug the power back in. Wait a few seconds for the first LED to go out and release the button. Go into the flash file system but typing "flash_init" at the command line. Then type "load_helper" at the next prompt. There should be a file there called "config.text" Kill that file or rename it. Then type "boot" to reboot the switch. You will be given the option to reconfigure.

Ok, after a few changes, I do have it set up right. Well, it is set up good enough for pc to work when connected. But, when I try to go in through a browser to check/change the configuration, I get a "topology under construction" message. This crappy Cisco CLuster Management really is buggy.

Thanks for all the help fellas.
