Hi Jeroen,
Gui doesn't display discovered arp entries.
Thanks for the tip regarding Lldp.

Hello Jeroen,
Today I tried to get the vrf´s via snmp. And yes, It is possible. This will
list the vrf´s :
snmpwalk -v2c -c com 192.168.0.1 1.3.6.1.4.1.9.9.468.1.1.1.2
The OID is on the cisco website, you can search the snmp object navigator for
it.
http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.4.1.9.9.468.1.1.1.2
It looks like that in my case:
iso.3.6.1.4.1.9.9.468.1.1.1.2.12.110.101.116.100.105.115.99.111.95.100.109.122
= STRING: "DMZ"
iso.3.6.1.4.1.9.9.468.1.1.1.2.12.110.101.116.100.105.115.99.111.95.119.97.110 =
STRING: "WAN"
iso.3.6.1.4.1.9.9.468.1.1.1.2.15.83.101.114.118.101.114.95.80.114.111.100.95.110.101.117
= ""
iso.3.6.1.4.1.9.9.468.1.1.1.2.24.110.101.116.100.105.115.99.111.95.115.101.114.118.101.114.95.112.114.111.100.95.110.101.117

Thanks,

Hi Sebastian,
The base design for Netdisco didn't include support for VRFs; I don't expect
any real VRF support coming to 2.x releases either, it's more likely to be
added when a lot of the code is redesigned for Netdisco 3.
In the mean time, I guess you've already found the options: live without the
ARP entries in different VRFs, treat every VRF on a box as an extra box in the
network, or hack around with custom data collection.
Do you happen to know if you can at least list the VRFs that are present via
SNMP? If so, that would open up possibilities to extend SNMP::Info to collect
the data you need.

Every time i manually discover juniper devices i get this:
[16848] 2015-10-30 20:07:51 debug [10.1.10.3] arpnip - processed 0 ARP
Cache entries
While ARP table on actual device is looking very populated.
Does anyone have any ideas what is happening ? Is netdisco using
incorrect SNMP mibs ?
