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
