   1. How to set up a SQL query to filter on all physical Ethernet
      switch ports? (Gerlach Tobias DLN FIII31)
--- Begin Message ---
Hello all,

My current challenge is to report all physical Ethernet switch ports.
So far I used the ifType "ethernetCsmacd" from the interfaces MIB (IF-MIB, 
http://www.net-snmp.org/docs/mibs/interfaces.html) as Ethernet is the only 
relevant protocol.
However, the result looks a bit odd and there's a lot of other interface types 
(ifType, http://www.net-snmp.org/docs/mibs/interfaces.html#IANAifType) and it's 
probably up to the vendors to correctly populate this table.
Any ideas on how to achieve this demand most accurately?

$ netdisco-do psql -e "select speed, count(*) from device_port where type like 
'ethernetCsmacd' group by speed"
