It seems that I still do not find them, even when adding the following to main.mk and re-running discovery:
#additional port-types for inventory
if_inventory_porttypes = [
'6', '32', '117',
'18', '22', '81', '101', '103',
if_inventory_portstates = [
Discovery still yields no results for any of these ports.
Some snmpwalks I did:
snmpwalk -v2c –c xxxxxx 6.x.x.x ifType |grep 503
IF-MIB::ifType.503 = INTEGER: propPointToPointSerial(22)
snmpwalk -v2c -c xxxxxx 6.x.x.x ifDescr |grep 503
IF-MIB::ifDescr.503 = STRING: Serial0/0/1:24
snmpwalk -v2c -c xxxxxx 6.x.x.x ifOperStatus |grep 503
IF-MIB::ifOperStatus.503 = INTEGER: dormant(5)
I would expect to see them discovered given the type (22) and Status (5) are part of main.mk, but I’m not 100% sure I did not miss a vital configuration component.
Thanks again for your suggestions-

Another problem beside the interface type mentioned by Marcel can be the state. Try also to inventory the down ports. I have some Cisco devices with serial port and these ports are most of the time down. They come only up if data is transferred.
