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
<inst>.
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
