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 <inst> specifies the SunFDDI/P interface
—x displays the received SMT frames in hexadecimal
—h displays help information, including a list of valid frame classes
<frameclass> 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:
# <basedir> /pf_smtmon [-i pf <inst> ] [—x] [—h] [ <frameclass> ]
# <basedir> /pf_smtmon -i pf1

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
