The only way to get DECnet information out of a cisco box, not
using the cli is to talk SNMP over IP (v4/v6) to it.
This leaves us with three problems:
- How to map a DECnet node number in to an IP address
That would require a table, listing any Cisco routers (or equivalent). Or, if the
neighbor is PyDECnet, I could add some implementation-specific attributes to the circuit
to show the circuit config parameters. Those aren't shown anywhere right now, but it
seems reasonable to make that visible. It would supply the other end's IP address,
unless the circuit and the SNMP daemon are at different addresses. (Is that possible with
Cisco?)
- Access control and enabling SNMP RO to some remote
addresses
Or just opening read to everyone; I don't know of a good reason to disallow that.
- Writing the SW to integrate this in to Pauls tool
(or some other tool)
I made a stab at that a while ago; it isn't all that difficult. The problem I ran
into is that Comcast has a mental problem, they filter SNMP traffic outbound so I
can't query anyone's MIB. The solution would be to build an SNMP proxy, which
would be easy enough, and install that on some helpful server.
A random thought: I wonder if it would be interesting for PyDECnet to implement the DECnet
MIB.
