show atm pvc "PPPoA Current State = LCP_NEGOTIATION" / WAIT_FOR_CALL

I am troubleshooting (MPLS VPN issue) ATM problem on Cisco 10000 router IOS Version 12.0(20020314:211744).

I have issued command

dsl#sh atm pvc ***/***

PPPoA Current State = LCP_NEGOTIATION

PPPoA Handle = 0xC4020E7E, SSS Handle = 0x3601048C

Switch Handle = 0x0D01075B, PPP Handle = 0xC7010FC9

AAA Unique ID = 0x1223F4CE, AIE Handle = 0xF2000159

PPPoA Debug(s): Event Error

This router is connected to MGX 8850 I can see cell count in MGX (Ingress & Egress both) from this router segment ping (atm pvc) is successful but I can do ping (atm pvc) device. I have noticed this changes

PPPoA Current State = WAIT_FOR_CALL

PPPoA Latest Event = AAA unique id allocated

PPPoA Latest Error = None

PPPoA Current State = LCP_NEGOTIATION

PPPoA Latest Event = PPP Msg

PPPoA Latest Error = None

Because of this my end user can’t connect to VPN.

Can anyone help me to solve this puzzle.

Re: show atm pvc "PPPoA Current State = LCP_NEGOTIATION" / WAIT_

Hello Ritesh, this is AL the guru, basically PPPoA Current State = LCP_NEGOTIATION / PPPoA Current State = WAIT_FOR_CALL means its waiting for the next LCP session from the PPP packet. Check to see if the users ADSL router is spitting errors when "debug ppp auth" and "debug ppp nego" is on. If its not check ADSL line to see if its in sync, if it is the break and rebuild the VC within the VP

one more thing, your ISP will have a plenty issue with 10K routers, they should have tested the IOS with the ATM link from the Telco to make sure IOS and ATM link with VP/VC works OK.
