Problems with Getting Frame Up and Running 1

I have a Cisco 2501 connected to an Astrocom SP100 to a frame connection. Whenever I try to bring the line up I get a "Serial1 is up, line protocol is down" message on the Cisco. I have insured that both Ciscos have an LMI type of cisco but no good. When I tyurn remote loopback on the one Astrocom the Telco says they can't see it. Would they be able to see the loopback?
 
Yes they should see the loop back . You may want to give a hard loop at the NIU , you
will need a patch cable and a adtran loop plug . Has your telco company been able to
sync up with frame relay ? Is your lmi-type matching what the carrier has set . Is your
DLCI correct ?

There are as you see several issues you can address, however just follow this list again .
1. Verify with the phone company all is ok ( ie bandwidth, DLCI, and Lmi-type )
2.Verify IOS programming interface and sub interface ( should be like this )
Router(config)#int ser0
Router(config-if)#encapsulation frame-relay
Router(config-if)#frame-relay lmi-type Cisco
Router(config-if)#no ip address
Router(config-if)#no ip directed-broadcast
Router(config-if)#no shut
router(config-if)#end
Now for the sub-interface
Router(config-if)#int ser 0.1 point-to-point
Router(config-subif)#frame-relay interface-dlci 16 IETF <----- IETF for none cisco
Router(config-subif)#ip address 192.168.1.1 255.255.255.0
Router(config-subif)#no shut

I hope this helps you out, Good Luck ! #-)
 
Which DLCI address is used in this case? The one for this end or the other end?
 
Your telco company should have given the DLCI's for each location. If your having trouble contact the telco's Advance Network Service ( ANS )and verify the provisioning . Be sure to have the frame-relays circuit numbers ready .
 
I did that as well as adding a keepalive 4 and frame-relay lmi-type ansi. But now it comes up and sends out lmi packets but never receives any. The telco says that everything looks ok. One weird thing is that one of the LMI lines list DTE LMI down. What could be causing this?
 
OK, here is the configuration, both routers are set up the same way:

interface Serial1
description 512K Frame-Relay to AspenCO
no ip address
ip helper-address 192.168.1.15
no ip directed-broadcast
encapsulation frame-relay
no ip route-cache
no ip mroute-cache
keepalive 4
appletalk cable-range 2-2 2.2
appletalk zone Wash D.C.
frame-relay lmi-type ansi
!
interface Serial1.1 point-to-point
ip address 206.0.105.1 255.255.255.0
no ip route-cache
frame-relay interface-dlci 100 IETF
 
In your sh int ser0 you should only see sending . If you receive this is because the
circuit is in test mode. Is LMI up on your interface ? If you type ( sh ip int br ) this will show the interfaces that are up . Do a ( sh frame-relay pvc ) and ( sh frame-relay map ) to see if the DLCI is active, inactive , or deleted . The programming looks ok , I was wondering about your secondary ip on the interface , that I believe is normally on the ethernet . Can you loop up to ANS ? This test will be clear as to were the problem is pointing too. If they can not see a loop it's a circuit issue , If they can than its a provisioning problem . Please keep me informed and I will help as much as I can . Good Luck !!!
 
When you say &quot;can you loop up to ANS&quot; what do you mean?
 
get an 8 conductor modular end and short pin 1 to 4 and 2 to 5 . You also can go into
your interface and type ( loopback line ) to turn it off type ( no loopback line). ANS should see this and run for about 3 minutes . The reason for a loop to ANS is to determind if the circuit is clean to the frame-relay Cloud.
When your clean to the cloud you should have your interface up and lmi up . If the protocol is down its provisioning to the other side ( your pvc's to be exact ) ... :)I
 
Just a thought on the way home . Is the frame relay t1's a full 24 chan are or they
fractional. If its a full T1 then your programming is ok . A fractional T1 say 512k with 6 chan, you would need to set up like this in the interface .( Service module T1 time slots 1-6 ) and increment up !!!!
 
It is a fractional T1 of 512KB. How would that be configfured?
 
Go into your serial interfcae that the frame relay is on and add
service-module T1 timeslots 1-6
 
Oops it should be
Service-modult T1 timeslots 1-8 Sorry !!!
 
The Cisco says that is an unrecognizable command?
 
I forgot that you are running another type of csu/dsu . On the csu/dsu device is were the number of chan have to be set up . I'm not sure how on the Astrocom SP100 how this is done ,and theres no literature on the SP100 at . There is an online Tech Support
maybe they can help , Good Luck !!!!
 
The Astrocom SP100 is setup right. I think it is a provisioning thing. How can I tell?
 
The port speed and the PVC speed are different. Port speed is 512KB and PVC is 256KB. Would that make a difference in the setup?
 
When I do a sho ip int br this is what I get. I know why serial1 line protocol is down, because the other end is down. But why is Serial1.1 method in manual mode and down in both cases?


AspenDC#sho ip int br
Interface IP-Address OK? Method Status Protocol
Ethernet0 192.168.1.2 YES NVRAM up up
Serial0 206.0.106.2 YES NVRAM up up
Serial1 unassigned YES NVRAM up down
Serial1.1 206.0.105.1 YES manual down down
 
on serial 1.1 do a no shut on the interface . The cir of 256 is a guaranteed speed from
your provider thats ok . Is the frame relay in question on serial 1 ?
 
I did that, no shutdown, on ser1.1 with no change. Should the DSU be set to 256 or 512?
