Issue #1830 has been updated by Marc CYPRIEN.
When a cable is created in the same site S1 they are not displayed. And when I
add the second cable in catX it looks like Netdot dislike it... It lets me
choose between S1 and S2 as ending site however there is no cable in S2.

Hello again,
I have two sites S1 and S2
I created two cable from S1 to S1 in different floor. One is fiber and the
other Cat6.
Now I try to see the backbone I have and Iselect S1 as beginning site and S1 as
ending site and i obtained the following error:

And I get the same error when I select S2 as ending Site but there is no
backbone cable in S2.
I only have the two backbone cable I mentionned previously.

Subject: [Netdot-devel] [Netdot - Bug #1828] Topology
To: [email protected], [email protected]
Message-ID: <[email protected]>
Content-Type: text/plain; charset=utf-8
Issue #1828 has been updated by Brian Candler.
RIght, so several things there.
(1) Lots of timeouts. Your devices aren't responding to SNMP queries properly.
You need to debug that. Look further into the debug bits that you didn't
include, see which device it was trying to talk to at the time, try using
snmpwalk to talk to it, generally sort it out.
(2) Netdot is falling back to doing topology discovery based on STP. This is
not as reliable as using LLDP. It'll be much more reliable if you turn on LLDP
everywhere.
On the Cisco: "lldp run"
See
http://www.cisco.com/c/en/us/td/docs/ios/cether/configuration/guide/ce_lldp-med.html#wp1092132
On the Dell: Looking at a 5524 here, I see
<pre>
interface gigabitethernet1/0/1
spanning-tree portfast auto
lldp optional-tlv port-desc sys-name sys-desc sys-cap 802.3-lag
lldp management-address automatic
</pre>
but I can't remember if those were set by default or I had to turn them on
manually across all interfaces.
(3) "Port 3/1 not found in Device: cisco"
That may be the problem I was telling you about interface names. Set
<code>IFNAME_SHORT=>1</code> in Site.conf
(Having said that, I found that problem in the LLDP MIB, not STP)
(4) Using SNMPv3 with that test script: go read the SNMP::Info documentation.
https://metacpan.org/release/SNMP-Info
Ask on the snmp-info list if you need help, or look in the Netdot code to see
how it invokes SNMP::Info with SNMPv3.
(5) In general, a bug tracker system is for tracking bugs, not user support. If
you're having problems using Netdot, please start with the netdot-users mailing
list.
https://osl.uoregon.edu/mailman/listinfo/netdot-users
When a bug has been identified (with details of how to reproduce it), then it
can be raised as an issue.

Hello,
When i am discovering the topology using bin/updatedevices.pl -T or during cron
job the topology change every time the command is done, sometime with the good
topology sometimes not.
In my network I have snmpv2 and v3, could it be the problem?
I don't know how to help you to find what is the problem, and for that I'm
sorry.
Do you have any idea of what could it be and can you help me?

fields to Asset
To: [email protected], [email protected], [email protected]
Message-ID: <[email protected]>
Content-Type: text/plain; charset=utf-8
Issue #1780 has been updated by Matej Vadnjal.
I was thinking about this a bit more. I agree it would make sense to have a
hardware box owner and used by info only in one place.
But what should happen if GET_DEVICE_MODULE_INFO is set to 0 in the config? Or
if a user has a device that has no asset (virtual machines, some obscure
hardware)? What should happen to owner and used by info in that case? In this
case there would be no way to add this info. Which is fine in my use case, but
I'm afraid this would break other peoples installs.
Or maybe we could "force" the user to create an asset and assign it manually to
the device if he wants to have owner and used by info.
I will give a go at a proper patch in the next few weeks if we can come up with
a reasonable solution to these questions.

Feature #1780: Add Owner and Used by fields to Asset
https://osl.uoregon.edu/redmine/issues/1780#change-3227

Status: In Progress
Priority: Normal
Assignee: Carlos Vicente
Category: DeviceManagement
Target version: 1.0.6
Resolution:
Attached is a patch that adds Owner and Used by fields to Assets.
Here is why we need this:
When a customer connects to our network, they need to provide their own SFP
module, that we plug into our backbone router. If a module happens to fail we
usually provide our own replacement since few customers are able to provide a
replacement quickly. After a while people forget that a module has been loaned,
tickets / emails get buried and nobody is sure anymore to who the module being
used belongs to.
With this patch I can make a script that will send reminders if an asset
plugged in a customer interface is not owned by that customer.
The patch was developed on top of current HEAD of master branch
(ecd83f76715...).

A Cisco 3750 adjacent to a Dlink DES-1210-28. The latter is an SNMP and

I expected that Netdot would infer the link between them using STP data, but it
doesn't.
Both devices exist as Netdot devices (Cisco is id=6, Dlink is id=16). Cisco is
running MSTP and Dlink is running RSTP - supposed to be backwards compatible?
