'k, but I want to use the managed aspect of it to be able to hard code the
port rates (ie. to fix this full-duplex issue initially) as well as be
able to access SNMP so that I can do bandwidth monitoring of external
traffic ... I have SNMP setup on the FreeBSD boxes right now so that I can
see network load per server, but I want to be able to isolate the
'external' traffic from 'internal', by monitoring the specific port that
is connected to the providers switch ...
So, in both cases, I need to assign an IP somewhere, correct?
