DCN: Cisco router cannot ping via clns a NE (ES)

[Spyros.Pentzouris]

Dear all,

I am facing an issue with clns config under a cisco 2640 which i can not ping a specific siemens DQ.

The message i receive is:

cnls ... cannot send echo..

The funny this is that i can see the neighbor with the clns neighbors (NSAP)...

Is anybody familiar with DCN config/design with both IP/OSI networks?

Thanks in advance,

let's try a 'trace clns' to the device that you cannot ping. This should give us some information on why it is failing.
