Re: genRtrConfig, router crash and old MIB

Hello,

I wanted the list to know that Luke and I are working on this problem.

At this point it seems to be confined to 7513 which are queried with the
deprecated OLD-CISCO-CHASSIS-MIB. Which has been replaced by RFC2737.
This RFC provides mechanisms to identify elements in relation to other
elements within a chassis as well as information about these.

I am working on providing a migration path for devices being managed
using to old MIB to the new RFC2737 compliant MIB.

In the mean time I will indicate how to turn off this functionality in
genDevConfig or genRtrConfig if you are not using the hierarchical
output function.

Cheers,

Francois Mikus
