NOTE If the optional Token-Ring telemetry interface is not installed, the probe will not
allow you to change the Fast Ethernet interface’s port type from telemetry.
If the Token-Ring telemetry interface is installed, you can configure either the
Fast Ethernet interface or the Token-Ring interface as the telemetry interface. The
Fast Ethernet interface comes from the factory configured as Telemetry and the
Token-Ring interface comes configured as Monitor/Transmit and is disabled.
“Disabled” in this case means that the interface does not function at all, not as a
Telemetry port nor as a Monitor/Transmit port. If you configure the Token-Ring
interface as Telemetry, the Fast Ethernet interface automatically becomes
configured as Monitor/Transmit and is disabled.
Port Type The Fast Ethernet interface can only be used as a Telemetry
port. The telemetry port does not maintain network statistics
for the Fast Ethernet interface. The telemetry interface only
allows the retrieval of ATM network statistics. Port 1 is the
Fast Ethernet interface and it is the telemetry port by default.
If the Token-Ring interface is also installed, you can select
either the Fast Ethernet or the Token-Ring interface (but not
both) as the telemetry port. Refer to “Token-Ring Telemetry
Interface Configuration” on page 29 for information on
configuring the Token-Ring interface. The probe must be
configured with exactly one telemetry port.
The Telemetry port only receives packets destined to the
telemetry port’s IP address, can transmit packets onto the
network, and is used for SNMP communications to the probe.
