Hi all,
my colleague made a SSHCollector script for arp records on IOS-XR. I'm
attaching the file here, and hope that it can be included in the next
release of ND2.
perl5/lib/perl5/App/Netdisco/SSHCollector/Platform/IOSXR.pm
And a question while we are on the SSHCollector subject, would it be
possible to maybe integrate the SSHCollector function so that it is
invoked by the "arpnip" command when applicable to "arpnipping". Or to
have an own type of command for SSHCollector scripts.
What I would like to be able to do is schedule it within the netdisco
config file, and also trigger it from the web-ui pushing the "arpnip"
button...
Tnx!

Great, many thanks! Yes we can include this in the next release.

Can you confirm that it's really the case that there's no SNMP support
for ARP tables in IOS-XR?

oliver.

We've tried it on IOS-XR 4.3.4 and the OID (1.3.6.1.2.1.4.22) for this
is not present, also I found a post at Cisco that suggests using CLI for
this.
https://supportforums.cisco.com/discussion/12003641/asr-9k-show-arp-mib
"narvenka@cisco: IP-MIB::ipNetToMediaIfIndex would have the capability
to do this. But currently the MIB is deprecated. Also querying the ARP
table in intense process. you can just run the script via vty and get
this done. It can be more effective too."
Brgds!

Hi Claes
Thanks, I have also included this in the Netdisco 1.3 version I'm
maintaining at <https://github.com/rc9000/netdisco-sshcollector>.

Hi,
We have a combination of Cisco and Arista Switches. Just installed ND2
and after running a Discover on our seed switch we are able to see the
systems that are attached to Cisco ports. I am not seeing anything attached
to the Arista Ports. Doing a discover on the Arista switch fixes this. Is
there anything else I should be doing to insure that the Arista switches
get automatically discovered? I can confirm ND2 found the Arista switches
because they are in the inventory list
Thanks

Hello,
currently discovering the first node has failed for several reasons. One
was: The UDP port of the switch choosen as the first node was reachable
(nmap and tracerout (UDP)), but netdisco-do -D discover was not able to
connect to the port. I assume, I have managed binding netdisco-do to IP v4
- but I have done too many changes to remember what I have changed.
What would have been the correct way to bind netdisco to IP V4?
Or are shall I consider other reasons for the problem?
IP V6 is neither configured on the switch nor on the network, but on the
Ubuntu Server 14.04 LTS I am using (Lubuntu).

Hi Michael,
There's no configuration or option in Netdisco for binding to a local
IP for discovery/polling.
I suggest you check your system configuration to find out why it's not
possible to connect.
Can you connect to the device using the "snmpstatus" command?
A useful technique is to run "ip route get x.x.x.x" which will tell you
the default local IP used to connect to the destination.
regards,
oliver.

Hi Michael,
The first error is a bug which will be fixed in the next point release.
The second error can safely be ignored. It is simply checking for Layer
3 support (which I guess this device does not have).
regards,
oliver.
