LMS 2.5 discovering devices over ISDN?

Hi,

I am trying to discover devices via BRI interfaces via a 3640 and 3725. Using seeds, router hops etc. seems to have no impact on the ability to discover these devices.

Do I need specific encapsulation the BRI interfaces?

I've enabled CDP discovery on the BRI interfaces but this has made no difference.

Any ideas / clues as to where I should be looking?

Thanks.

OK, checked everything out and I'm getting:

Getting the message:

3w3d: CDP-EV: Encapsulation on interface BRI2/0 failed

3w3d: CDP-EV: Encapsulation on interface BRI2/1 failed

Just using normal PPP encapsultion on the BRI line with image 3725-js-mz.122-15.T17.bin

Do I need to change the encapsultion, type of image or ..... ??

Thanks.

If you read the document

http://www.cisco.com/en/US/products/sw/cscowork/ps563/products_tech_note09186a0080094949.shtml#topic1

you find this:

"Basic Rate Interfaces (BRIs) do not support CDP. Enhancement request CSCdu20683 is opened against this. As a workaround, configure a dialer map to send the CDP packets. CDP is supported on dialer interfaces. "

in the Bugtool CSCdu20683 is not listed.

regards,

Martin
