Cisco 2900xl ping and telnet issues

Ok, I have another question regarding this Switch. I have successfully configured the switch to give our voice traffic priority, and can gain access through the console port. However, after configuring the switch and rebooting I can no longer ping the switch (I used to be able to do so) and I can not gain access through telneting from other terminals. Once again, I used to be able to telnet in, I just didn't have the correct password. I have the switch performing the way I want (I think), but I don't want to have to connect a console terminal up and do a password recovery every time I need to make an adjustment. I am a software engineer, not a network guru or Cisco certified tech so I would appreciate if you gurus would cough up some of your magic.

Well one thing i want to ask is if you are doing a copy run start or wr on your CLI? this will save your changes that you have just made from your running configuration which is in your system ram to your startup configuration which is in your rom/flash. If you dont execute this command then every time you reboot the switch and or power outage then you will have a blank switch with no configuration on it. If you need an example of putting an ip on a switch or configuring for telnet access then just reply back

Keep in mind that I now realize that I should have performed a:
Switch(config)#no enable secret
before I did:
Switch(config)#enable password guessme
So I am not sure what worked and what didn't, but I did do:
Switch(config)write memory when I was done.

Nothing I did should have affected telnet ability, but I can no longer ping the switch or telnet into it from outside machines. I can still gain access through the console port and see that my changes giving a particular port CoS priority are in affect and apparently working (at least until the next reboot).

Any advice you can give me to set this thing up correctly and more permanently would be appreciated.

 

Well if your configs were wiped then you lost an ip to ping and telnet to as well as closing your vty lines.

I reccomend you do a
no enable password guessme
enable secret guessme

From your console do a sh ip int bri
See if your Int Vlan1 has an IP and shows as UP UP.
If this is not the case you will need to put an IP on vlan1 to be able to telnet again.

You will also need to allow telnet to process on your device

switch(config)line vty 0 4
switch(config-line)password guessme
switch(config-line)login (this is important)

This opens up your VTY lines for telnet access.

OK, thanks. I am going to have to go back in and play a little before I can respond intelligently to any of that. Keep in mind I am a complete novice when it comes to Cisco devices, so you are talking greek when you say:

sh ip int bri

I will look that up and try it out and get back with you. Thanks.

LOL..thats ok..
sh ip int bri means show ip interface brief

This is a good command to see what interfaces you have up on a device.

I am here to help.

 

globalchicken if you are still out there, Please see my new thread for the continuation of this saga.

 

Where is it? your post?

 

Thats a darn good question. Took me over 15 minutes to type it. It said it posted, does it need to be reviewed first ?????
