NetXMS Support Forum

I can confirm that netxms has at least two bugs with juniper EX:
1) Netxms does not correctly recognized vlans on junipers.
I'm not able to identify a specific pattern of the behaviour because wrong vlans are random and it does not depends on firmware or specific model , for example a single interface has sometimes a lot of vlans (like the trunk) when it should be only one, sometimes instead it has wrong vlanid or empty vlans .
2) Netxms does not always recognize Lldp neightbours printing an empty LLDP table in node tools (and obviously macaddr search does not find his neighbours). I'm using this script https://github.com/stanislavb/snmp-lldp to verify that lldp is correctly exported via snmp for those nodes.

I put some data of a juniper for the vlan bug:

Hi!

NetXMS server do walk on .1.3.6.1.4.1.2636.3.40.1.5.1.7.1.5 to collect port membership (but result should be the same as walking on .1.3.6.1.4.1.2636.3.40.1.5.1.7.1.3).

In your data port ge-0/1/3 has ifIndex=552, but I don't see it in VLAN port table (there should be entry with OID SNMPv2-SMI::enterprises.2636.3.40.1.5.1.7.1.3.nnn.552, where nnn is index in VLAN table).

Same for ge-0/0/16: it has ifIndex=534, and it has multiple entries in VLAN port table:
SNMPv2-SMI::enterprises.2636.3.40.1.5.1.7.1.3.2.534 = INTEGER: 3
SNMPv2-SMI::enterprises.2636.3.40.1.5.1.7.1.3.5.534 = INTEGER: 3

SNMPv2-SMI::enterprises.2636.3.40.1.5.1.7.1.3.23.534 = INTEGER: 3
which corresponds to VLANs CP-1, SSO-3, SSO-12, SSO-UnautenthicatedDevice, Example1, Example2, n9-2.

If this does not correspond to actual device configuration then it looks like device reports incorrect information via SNMP.

Best regards,
Victor

Sorry, but i think this is not right, and probably is the reason of the netxms bug:

According also to:
https://supportportal.juniper.net/s/article/EX-How-to-retrieve-interface-names-mapped-to-a-specific-VLAN-using-SNMP-MIB?language=en_US

In the SNMPv2-SMI::enterprises.2636.3.40.1.5.1.7.1.3 oid is not present the snmp ifindex, but the translated dot1dBasePortIfIndex ( 1.3.6.1.2.1.17.1.4.1.2)

Netxms instead use the ifindex ( 553 ) so the vlan is not assigned (because not exists in the mapping) or when exists it's wrongly assigned to a different interface:

# Example of an interface incorrectly recognized by netxms:
snmpwalk -v2c -c public 172.x.x.x 1.3.6.1.4.1.2636.3.40.1.5.1.7.1.3.23.534
SNMPv2-SMI::enterprises.2636.3.40.1.5.1.7.1.3.23.534 = INTEGER: 3

# The wrong assumption
snmpwalk -v2c -c public 172.x.x.x 172.29.1.25 1.3.6.1.2.1.2.2.1.2.534
IF-MIB::ifDescr.534 = STRING: ge-0/0/16

and indeed in my previous post screenshot, the vlan is incorrectly assigned to ge-0/0/16

Thank you for digging this! I just changed Juniper driver to use bridge port number instead of ifIndex to identify ports in VLANs. Fix will be included into release 4.3.1. If you want to test it before release I can provide intermediate build, just let me know what platform you are using.

ok, i can test it in next days. I prefer a deb package for debian 10.
Thanks

Hi

I've pushed 4.3.0.52 to test repo. You can add following source:
deb http://packages.netxms.org/test buster main


I confirm it works, for virtual chassis too. Thanks.

Just one request concerning a different issue:
is it possible to add the "vlan view" (in the Topology menù) also in the node overview tab in order to have a visual display of their port status? The port view does not display vlans, don't know if the reason is that vlans are on logical interfaces or for design.
