Cisco to Nortel ATM PVC Configuration

[IMRAN MANGA]

Hi,

Am having trouble getting the line protocol up when trying to connect a customer over an ATM link. The customer has a nortel router. Any specific parameters to be configured.

Don't have this issue with other customers using Cisco routers.

Thanks

Imran.

Hello Imran,

can you post the configuration of the Cisco router, and the relevant parts of the ATM PVC config of the Nortel box (if you use e.g. SpeedView, post the screenshots) ? Which Cisco and which Nortel boxes are you using ?

Regards,

GP

Hi,

Here's the Cisco 7500 router config

interface ATM1/0/0.5 point-to-point

description CUSTOMER

ip address X.X.X.X 255.255.255.252

ip verify unicast reverse-path

no ip directed-broadcast

no ip mroute-cache

no atm enable-ilmi-trap

pvc 11/100

vbr-nrt 8192 8192

oam-pvc manage

encapsulation aal5snap

The other end is a 5430 passport Nortel router, I do not have the configs for the Nortel box.

Any suggestions ?

Thanks

Imran.

I would verify the Nortel is configured with the correct PVC and encapsulation type.

Can you post show int and show atm vc 11/100

Hello Imran,

is it possible to get into the Nortel box ? We need to verify that at least the PVC in the Nortel is enabled, and that the aal5 encapsulation is set correctly. Who is your provider ? Can you check with the provider that the PVCs are both defined and active at the provider's end ?
