mnet not discovering network #23

Open MadPAM opened 6 years ago

MadPAM commented 6 years ago

Hi, I'm trying to discover part of our network. I start at that sites core switch and it gets discovered without issues. But the scripts says that it found 0 links. The core is a pair of 6506 running VSS and bootdisk:/s2t54-adventerprisek9_npe-mz.SPA.152-1.SY3.bin (from the devices file). Here is the output of mnet.py: Config file: network.txt Root node: 10.18.224.1 Output file: network.png Crawl depth: 10 Diagram title: MNet Network Diagram Out Catalog file: devices.txt

I have the subnet included in the settings file: "subnets" : [ "10.18.224.0/24"

There are currently 9 switches connected to this main switch and all of them have cdp enable. Walking 1.3.6.1.4.1.9.9.23 shows them just fine. Not sure how the script discovers them.

Anybody have a hint what could be happening?

I'm using Python 2.7 on Windows Server 2012 R2.

as an FYI - if I run the same script from Linux it works! This is using the same settings and devices to discover...
