Manual config of a Cisco 1720 - newbie 1

I have a Cisco 1720 on a fractional T1. When we first set this up, the original consultant added the timeslots command thru the console. We were attempting to open ports for VPN access using config-maker. We read the router and saved the config, made the changes to open port 1723 and went to write this back to the router. The timeslot config statement disappeared from both the current config and the backup (as it seams that config-maker doesn't understand that command), and we could no longer access the internet. I tried to add the statement in the IOS config part of config-maker but it will not add it to the router.

The original consultant is unavailable to help.

Can someone help me with configuring the timeslots statement thru the console? I can get to the router# prompt but get stuck after that.

I need to add under the interface serial 0 the command
service-module t1 timeslots 17-24

Thanks in advance for any and all replies

Here is the config.

I will try:
after connecting to your router:
enable
(enter your enable password if neccessary)
conf t (to enter configuration mode)
int serial 0 (to enter config mode for your interface)
then enter your command
after that:
end to go back to enable mode.

Is that what you needed?

Hope this helps,

Thanks,

That did allow me to configure the timeslots and the router now shows the interface to be up, and I can now ping the static IP of the router.

Now , however it appears that the fast ethernet interface has failed. It shows that it is configured (192.168.1.1) but cannot be pinged. I tried to reset the router to do dhcp and put it and one pc on a switch and the pc cannot get an IP.

Any Ideas or am I looking at either repairing or replacing this router?

 
Where can't you ping it from? a pc or the router itself?
 
Hi,

I cannot ping the router from the lan side. Pinging 192.168.1.1 gets either a time out error or a destination net unreachable error. I can ping the router from the outside.

When I query the router thru the console, it shows the ethernet port to be configured as 192.168.1.1, the router and the switch show connectivity with the idiot lights, but thats as all.

To restate my actions, I connected the router and a pc to a switch, the switch shows 100mhz connectivity with the router and the pc. Pinged the router from inside and got request timed out or destination net unreachable.
Reset the router to do DHCP with an internal address of 192.168.1.1 and DHCP range of 192.168.1.100-200. Set the pc to receive an IP from DHCP and the pc gets nothing. Reset the pc to 192.168.1.2 and ping the router, either gets request timed out or destination net unreachable.

The pc does talk to the rest of the network (just to rule out pc to network connectivity)
 
have you tried the following?
set the PC to receive an ip address via DHCP/ Configure the router for DHCP / on the PC(Windows?) open a dos window /
type in: ipconfig /renew (had some similar problems lately)

Is the status of the internal ethernet interface still up?
Can you post the configuration of the DHCP on the router?
When you set the ip address to 192.168.1.2 did you have the same subnet mask as you have on the router?
 
The pc was not receiving an address at all. It configed itself with the Win2K 169.x.x.x address.

Ipconfig /renew did not work

The router is showing up for both interfaces (serial0 and Fastethernet0)

Router is set for 192.168.1.1 with a mask of 255.255.255.0 and the pc was set for an address of 192.168.1.2 with a mask of 255.255.255.0

DHCP config of the router
address range 192.168.1.100 thru 192.168.1.200 mask of 255.255.255.255
DNS settings were that of out internet provider.
 
Hi cranbiz,

although this is probably not the problem(because it didn't work with the 192.168.1.2) I think that your DHCP config might not be completely right(subnet mask).
You might try something like this:
ip dhcp pool CLIENT
import all
network 192.168.1.0 255.255.255.0 (is now set for 192.168.1.0-192.168.1.255)
default-router 192.168.1.1
lease 0 2

But I think there is something more not working correct, what I can't see because of missing knowledge.
But people out here are really clever. You should find someone who can help you.
