If you have Cisco switches, you could enable CDP on the ESXi as well...

Yes you can.
If you know the links and ports NeDi allow you to add links manually.
Please go to Topology and select Linked option.
where you have to select correct device and ports and than Add it.

I hope this will help you.

Discovery / vmware host without distributed switches
« Last post by reenosmith on March 05, 2017, 11:44:29 AM »
Hi,

What awesome software this is - thank you.

I look after smaller organisations that still want the network diagrams Nedi produces.

My issue is they don't have the top end vmware licences that allow for distributed switches.

So when I run the discovery I get my hots and VMs show up but they are not linked to anything - my maps show them all separated.

How do I link the VMs to their hosts if I don't have distributed switches?

Can this be done manually or is there some software I can install on the VMs so this is picked up automatically by Nedi?

Hi Gerold,

testing against a Nexus 9300 works fine. Indeed it looks like NeDi uses Telnet on Port tcp/222.

I will ask, but I think it's just reading ARP tables from other devices (using SSH or Web/REST) and presenting the data through SNMP...

Hi again!

In your initial post it looks like NeDi is using the telnet protocol ("TEL") to connect to your SSH server on port 222/TCP.

SSH is only used by libcli.pm when the port number is 22.

Hope this helps

Definition files are located in /opt/nedi/sysobj/. You need a definition file for each device. I suppose you don't have one for your device. Try to find out the sysobject id and define a file. Best is to clone/edit an existing file.

snmp access is defined in

/opt/nedi/nedi.conf:
Code: [Select]
#============================================================================
# Device Access
#============================================================================

# Set SNMP communities (preferred ones first).
# If authentication protocol is set, it will be treated as v3

#       name    aprot   apass           pprot   ppass
comm    public
;comm   private
;comm   paranod md5     ver3pa55        aes     ver3pa55
;comm   initial md5     ver3pa55        des     ver3pa55
;comm   initial md5     ver3pa55

After that rescan your device with

Code: [Select]
/opt/nedi/nedi.pl -a [device] -v
and have a look at the output.

Hi Gerold,

we're running

Code: [Select]
server:/ # ssh nedi@xxx.xxx.xxx.xxx -p 222
User Access Verification
Password:
Cisco Nexus Operating System (NX-OS) Software
[..]
Switch# show running-config

!Command: show running-config
!Time: Mon Feb 20 08:08:50 2017

version 6.2(16)

on N7K-SUP1 (Nexus 7018). In my (v1.0.9) libcli.pm the following applies:

Code: [Select]
$cmd{'NXOS'}{'conf'} = 'show running-config';
$cmd{'NXOS'}{'strt'} = '^begin|running-config';

Think that's ok. Is there a possibility to see what nedi really sends to the switch and what receives it?

Hi Remo,

thanks for the hint, the arpwatch file looks like a good starting point - at least for IPv4.

Is your other customer willing to share any details or code of his SNMP proxy solution?

Best regards,

Gerold

Hi,

after a quick glance at libcli.pm, I'd guess that nedi is waiting for the config start pattern, which for
NXOS is initialized as follows:
Code: [Select]
$cmd{'NXOS'}{'cfst'} = '^begin|running-config';

What kind of Nexus device are you trying to backup?

On our Nexen (5500s and 9500s), backup works as expected.
"show runn" output starts with
Quote
!Command: show running-config
which matches the regex above.

Hope this helps!
