Can't configure frame relay T1 on Cisco 1760

Question

I am trying to configure a data T1 via a Frame Relay.

The ISP provided me the following information:

1. IP address
2. Gateway address
3. Encapsulation Frame Relay
4. DLCI 100
5. BZ8 ESF (I think the bz8 was supposed to be b8zs)
6. Time Slot (1 al 24).

And what I have configured up until now is the following:

interface Serial0/0
  ip address <ip address> 255.255.255.252
  encapsulation frame-relay
  service-module t1 timeslots 1-24
  frame-relay interface-dlci 100

sh service-module s0/0 (outputs):

Module type is T1/fractional
    Hardware revision is 0.128, Software revision is 0.2,
    Image checksum is 0x73D70058, Protocol revision is 0.1
Receiver has no alarms.
Framing is **ESF**, Line Code is **B8ZS**, Current clock source is line,
Fraction has **24 timeslots** (64 Kbits/sec each), Net bandwidth is 1536 Kbits/sec.

And everything seems to be accounted for to me, but apparently I'm missing something.

My issue is that I'm stuck on interface up, line protocol down, so the T1 doesn't go up.

Well what's the problem exactly? You haven't stated what kind of trouble you're having. Also, can you post the output of "sh int"? — joeqwerty, Dec 06 '12 at 00:43
you should map the ip of the remote gateway in that p2p to the dlci as well :) such as frame-relay map ip 192.168.0.1 100 — ItsGC, Dec 06 '12 at 01:10
Hi @ItsGC the frame relay map command is giving me the following error **FRAME-RELAY INTERFACE-DLCI command should be used on point-to-point interfaces**. I'm specifying the command like so: frame-relay map ip 100. And I'm specifying it on the subinterface that has the frame-relay interface-dlci 100 configured. Is this correct? — sonar, Dec 06 '12 at 02:11
Well it seems you have L1 and L2 issues so my L3 comment is hardly relevant at the moment :) — ItsGC, Dec 06 '12 at 02:27
Please post the relevant parts of the configuration - specifically the configuration of s0/0 and s0/0.1. — rnxrx, Dec 06 '12 at 03:56
You have a yellow alarm, the problem is on the far end. Make sure the ISP has actually enabled your port on their end. Make sure the telco has released the line. — David Schwartz, Dec 06 '12 at 11:24

You're showing a remote alarm, for that you may find Cisco's troubleshooting guide useful.

Assuming the hardware is good...

I'd check the cabling between your router and the demarc, make sure it's plugged in, not damaged, not a bad cable, etc. Then I'd call the ISP and ask them why it isn't working. Last time I had this happen, it was because AT&T had screwed up and gave me the wrong DLCI, which took a six hour conference call to figure out...

From your update, I see:

     1725 input errors, 595 CRC, 1099 frame, 0 overrun, 0 ignored, 30 abort

Someone more experienced may have better ideas, but this definitely makes me think you have an issue with your cabling, or a noisy line, or the telco clock is completely wrong. It's probably time for that conference call.

Hi @Michael I tried the hardware loopback, and it didn't generate any remote alarms. So I guess the hardware is OK. Although is not like I could ping it. I mean the line protocol never did come up. I trying my luck to see if there's a mistake on the DLCI's. Thank you. – sonar Dec 06 '12 at 01:40
I know, your right. It sucks because I really wanted to finish this today. – sonar Dec 06 '12 at 02:38

The ISP had setup the wrong DLCI. We are up and runnign now. To anyone else having a similar issue take a look at this guide by Cisco it was invaluable. http://www.cisco.com/en/US/docs/internetworking/troubleshooting/guide/tr1918.html#wp1020680 – sonar Dec 06 '12 at 22:03
