Selected Probe or SNMP Device Properties 259
Note: When switching from Advanced to Switched mode, you must
configure Observer for switched operation. Details on how this is done are
found in the “Switch Configuration” section of this manual.
Probe Parameters Tab
• “Network type”—displays the Probe’s network topology. Possible topologies include
Ethernet, Token Ring, FDDI, and Dialup.
• “Network speed”—displays the network speed.
The distinction here is between the actual, measured speed of the network
and the speed that the NIC card, possibly incorrectly, reads from its
connection. For example, a 10/100MB NIC card on a 10/100MB connection
to a switch on a network where all the other stations are running at 10MB will
report the network speed as 100MB.
This item is the actual number that the NIC card driver sends Observer, so
10MB Ethernet will be reported as “10,000,000”. 100MB Ethernet will be
reported as “100,000,000”.
• “NIC hardware address”—displays the hard address of the Probe’s NIC.
• “NIC card name”—displays the name of the card as reported by the NDIS driver to
the registry.
• “NIC card driver name”—displays the name of the card driver as reported by the
NDIS driver to the registry.
• “Probe (Local Observer) VxD”—displays the name of the driver file used by the local
Observer or Probe.
• “Number of adapters”—displays the number of cards the local Observer o r Probe has
configured.
• “RAM available (MB)”—displays the amount of RAM the local Observer or Probe
reports have available.
