How to enable Auto VC configuration in ATM interface?

Hello,

I am trying to auto provision a cisco 2600 CPE with ATM/IMA links using ILMI. This CPE is connected to a DSLAM. Basic ATM interface parameters are successfully exchanged using ILMI. However, the PVC configurations in the DSLAM are not trasnferred to the CPE through ILMI.

When I do a "sh int atm1/0" in the CPE, I see that "VC Auto creation Disabled".

How can I enable VC auto creation on this interface? I don't see any command to enable this feature. Please let me know.

Thanks,

Vijay

Note: I enabled ilmi-pvc-discovery on that interface, but the VC Auto Creation is disable always.

Hi Vijay

Try this Url

http://www.cisco.com/en/US/products/sw/iosswrel/ps5012/products_feature_guide09186a0080140037.html#wp1024430

Also try the following commands

Router(config)#network change participate wic 0 or

Router(config)#networ clock source e1 0/1

Do rate if works.

Thanks for the response Imran.

I already tried the options mentioned in the link that you sent. However, I could not see 'create on-demand' command in my 2621 CPE.

I don't see the network commands either.

Re: How to enable Auto VC configuration in ATM interface?

Dear Vijay,

Pls try putting following commands on your router.Hope this work

controller E1 0/0

mode atm aim 0

controller E1 0/1

mode atm aim 0

(router)#network-clock-participate wic 0

(router)#network-clock-participate wic 1

(router)#network-clock-participate aim 0

(router)#network-clock-select 1 E1 0/0

(router)#network-clock-select 2 E1 0/1

Under global configuration u need to create an ATM/AIM interface in the following way.

interface ATM0/0

description --- XNR= DNA= MTN Port=

no ip address

mtu 1500

no ip address

no ip redirects

no ip proxy-arp

no atm auto-configuration

no atm ilmi-keepalive

no atm address-registration

no atm ilmi-enable

interface ATM0/1

description --- XNR= DNA= MTN Port=

no ip address

mtu 1500

no ip address

no ip redirects

no ip proxy-arp

no atm auto-configuration

no atm ilmi-keepalive

no atm address-registration

no atm ilmi-enable

interface ATM0/IMA0

description --- XNR= DNA=MTN Port=

mtu 1500

no ip address

no ip redirects

no ip proxy-arp

ip route-cache flow

load-interval 30

no atm auto-configuration

no atm ilmi-keepalive

no atm address-registration

no atm ilmi-enable

Re: How to enable Auto VC configuration in ATM interface?

Dear Imran,

Thanks for the response. I tried the commands similar to the one you gave, but I still cannot get 'create on-demand' commands in the CLI for PVC configuration. May be I have the wrong IOS. Mine is 12.3(18).

In the configuration you sent, ILMI is disabled. But I need ILMI to be enabled for my testing. After enabling ILMI, I could see ATM interface parameters being exchanged successfully with the router.

After this PVC auto configuration is supposed to happen. But the PVC auto configuration is not happening. Such a request should come from router but i could not see it.

When I do a sh int atm 0/0, I see a line "VC Auto creation disabled". Do you know how to enable this? I enabled atm ilmi-pvc-discovery. But the VC Auto creation remains disabled in the sh atm command. I think PVC configuration is not happening because of this. If I can enable this, then probably PVC information will be sent from DSLAM to router over ILMI PDUs successfully.

Thanks for your response.

Hi Imran,

Thanks for the information. I believe the pdf document is same as the link that you sent before. Those commands are available in my CPE.

Thanks for your assistance anyway.
