Monitoring SMT Frames

(pf_smtmon)

The

pf_smtmon(1M)

utility is an active monitor that displays the

SMT

frames

received by the local station. It is particularly useful for diagnosing
communication problems with the SunNet Manager proxy agent.

This command must be executed as

root

(or

superuser

) and has the general

form:

—i pf

specifies the SunFDDI/P interface

—x

displays the received

SMT

frames in hexadecimal

—h

displays help information, including a list of valid frame classes

specifies one or more

SMT

frame classes (used to filter output)

If you do not specify an interface,

pf_smtmon

returns the

SMT

frames received

by

pf0

. If you do not specify a frame type,

pf_smtmon

displays all the SMT

frames that it receives. Use

Ctrl-C

to stop

pf_smtmon

.

To display the encoded

SMT

frames received by interface

pf1

, type:

The elements of the SMT frames are defined as follows:

#

/pf_smtmon

[-i

pf

] [—x] [—h] [

]

#

/pf_smtmon -i pf1

pf1: nif_request v=0x1 t=0xfc03e781 s=10-0-4-48-6f-a5 i=0x28

pf1: nif_response v=0x1 t=0xfc03e781 s=10-0-4-8-24-5c i=0x28

pf1: nif_request v=0x1 t=0xfc00dec6 s=10-0-4-b8-6e-ab i=0x28

class_type

Identifies the SMT frame class and type (see page 100)

v

Version ID; identifies the structure of the

SMT

information field

t

Transaction ID; used to pair

SMT

response and request frames

s

Station ID; uniquely identifies the station transmitting the frame

i

InfoField Length; defines the length of the SMT information field
