Hi,
I’m reporting a missing “Neighbors” tab on newer Huawei switches (S5735 V200R022 and S5755 YunShan OS).
The issue: LibreNMS does not show the Neighbors tab, and the discovery-protocols module returns empty for LLDP-MIB.
Evidence:
-
Standard LLDP-MIB (
1.0.8802.1.1.2) returns: No Such Object. -
Proprietary HUAWEI-LLDP-MIB (
1.3.6.1.4.1.2011.5.25.134) returns data:
iso.3.6.1.4.1.2011.5.25.134.1.1.1.0 = INTEGER: 1
iso.3.6.1.4.1.2011.5.25.134.1.1.2.0 = IpAddress: 10.xx.xx.xx
iso.3.6.1.4.1.2011.5.25.134.1.1.5.1.11.1 = INTEGER: 6
(truncated...)
It seems these newer firmware/models require LibreNMS to use the Huawei-specific OIDs for LLDP discovery.
System Info:
-
LibreNMS: 26.5.1-dev.4
-
PHP: 8.4.16
-
OS: Huawei VRP / YunShan OS
Could someone help update the OS definition or provide guidance on adding support for this MIB? I can provide full snmpwalks if needed.
