dot1dBasePortIfIndex snmp info missing on SLX9740-80C

jarnot — Tue, 02 Jan 2024 18:17:30 GMT

We have a number of SLX devices and are using LibreNMS to pull info from them.

For some reason dot1dBasePortIfIndex OID is missing on the newer SLX9740-80C platform, whereas SLX9740-40C returns the proper snmp oid. They're both running the same os version, so I'm confused as to why my vlan tab is empty. This isn't the first peculiarity I've seen with extreme mibs. The lldp info isn't showing up but that's a different topic...

Any ideas or help would be appreciated.

Working:

snmpwalk -v2c -c <snmp string> <SLX9740-40C ip> -m 'BRIDGE-MIB' -M '/opt/librenms/mibs:/opt/librenms/mibs/extreme' | head -1 SNMPv2-MIB::sysDescr.0 = STRING: Extreme SLX9740-40C Switch/Router, SLX Operating System Version 20.4.3a. snmpwalk -v2c -c <snmp string> <SLX9740-40C ip> -m 'BRIDGE-MIB' -M '/opt/librenms/mibs:/opt/librenms/mibs/extreme' .1.3.6.1.2.1.17.1.4.1.2 BRIDGE-MIB::dot1dBasePortIfIndex.20 = INTEGER: 201490688 BRIDGE-MIB::dot1dBasePortIfIndex.32805 = INTEGER: 671088677 BRIDGE-MIB::dot1dBasePortIfIndex.32806 = INTEGER: 671088678 BRIDGE-MIB::dot1dBasePortIfIndex.4294967295 = INTEGER: 2080407565

Missing:

snmpwalk -v2c -c <snmp string> <SLX9740-80C ip> -m 'BRIDGE-MIB' -M '/opt/librenms/mibs:/opt/librenms/mibs/extreme' | head -1 SNMPv2-MIB::sysDescr.0 = STRING: Extreme SLX9740-80C Switch/Router, SLX Operating System Version 20.4.3a. snmpwalk -v2c -c <snmp string> <SLX9740-80C ip> -m 'BRIDGE-MIB' -M '/opt/librenms/mibs:/opt/librenms/mibs/extreme' .1.3.6.1.2.1.17.1.4.1.2 BRIDGE-MIB::dot1dBasePortIfIndex = No Such Instance currently exists at this OID
