Interpreting Statistics from Neighboring Stations
Running the
pf_stat
utility with the
—m
option displays information about the
neighboring stations attached to the local interface
pf
Phy (Physical Connection)
PHY shows the type of physical connection to the FDDI network. This heading
is modified to indicate the type of port being managed:
•
PhyS
: single-attached station, port S
•
PhyA
: dual-attached station, port A
•
PhyB
: dual-attached station, port B
The following states may be returned by
pf_stat
under the
Phy
heading:
Frame (Frames Received)
Running
pf_stat
without an interval and count displays the total number of
SMT
frames received since the interface was activated. Running
pf_stat
with
an interval and count displays the number of
SMT
frames received since the
last interrogation.
More detailed information about the
SMT
frames can be recovered using the
pf_smtmon(1M)
utility described in “Monitoring SMT Frames (pf_smtmon)”
Error (Error Frames)
Running
pf_stat
without an interval and count displays the total number of
error
frames received since the interface was activated. Running
pf_stat
with an interval and count displays the number of
error
frames received since
the last interrogation. An
error
frame is defined as an
SMT
frame whose
E
(error) bit is set, and whose
E
bit is first detected by the local station. It does
State
Meaning
NONE
Port disconnected
M
Port connected to Port M on a concentrator
S
Port connected to Port S on a single-attached station
A
Port connected to Port A on a dual-attached station
B
Port connected to Port B on a dual-attached station
