Hello all,
I’m very new at this, so please go easy on me…
I’m trying to get the network map to show something, but all I get is:
No map to display, this may be because you aren’t running autodiscovery or no devices are linked by mac address.
My main switch is a Netgear FS728TPv2 with only the default VLAN in use.
None of the tabs under this object show any MAC addresses of connected devices. It shows all of the ports, but not the MAC addresses of the endpoints connected to those ports.
Running discovery.php, I see that it reports lines like:
SNMP[‘/usr/bin/snmpbulkwalk’ ‘-v2c’ ‘-c’ ‘COMMUNITY’ ‘-OQUsetX’ ‘-m’ ‘Q-BRIDGE-MIB’ ‘-M’ ‘/opt/librenms/mibs:/opt/librenms/mibs/netgear’ ‘udp:HOSTNAME:161’ ‘dot1qVlanFdbId’]
dot1qVlanFdbId[0][1] = 1
dot1qVlanFdbId[0][2] = 2
vlan 1 mac 000b8239b8ba port (6) 17
vlan 1 mac 000b82405dbb port (3) 14
vlan 1 mac 000b8245c6ad port (1) 12
vlan 1 mac 000b824611c8 port (28) 39
…
for every port, and for ports that are connected to other switches, it shows multiple MAC addresses for the same port, as I would expect. But even though it clearly has the data, it’s not creating a map showing this switch and it’s connected devices.
It actually doesn’t work for any of my switches, but I figured I’d start with this one and troubleshoot the rest as I learn from this one.
If I manually run:
snmpwalk -v 2c -c eWdYw5A2xOSDuu.A 10.1.5.26 1.3.6.1.2.1.17.7.1.2
it will report the data.
So I tried adding “- .1.3.6.1.2.1.17.7.1.2” under the sysObjectID: section of netgear.yaml, but that didn’t improve anything.
From what I can tell, the OS, MIBs, OID’s seem to be identified correctly since the correct data is pulled.
I would expect the discovery scan to create a map showing various switches and endpoints based on the MAC address and port information reported by the switch. Is this not what I should expect? If not, how else would I generate a map showing switch interconnects and endpoint objects?
Any help would be appreciated.
Thank you
