[mrtg] Re: What is the IP of generating hosts?

[Peter P. Benac]

Jim,

    'sc0' is the supervisor card in the device.  If you continue down the
config file you will see ifIndex 64 assigned to the port that Fluke sees and
that Cisco Switch reports.

    You are mixing apples and oranges here. The IP address is NOT assigned
to the port. It is assigned to the VLAN (VLAN1 by default).  That switch
would happily go about it's business of being a layer 2 device even without
an IP address on it.  IP addresses are only valid at layer 3 and above.

Regards,
Pete
