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)”
on page 98.
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
