SELECT Command
PACKET [ packet-type [, packet-type ] ] ...
packet-type is one of the following values:
CALL REJ
CLEAR RESET
DATA RESTART
DIAGNOSTIC RNR
INTERRUPT RR
NOTRR
NOTRR displays all packets but RR packets. Omitting packet-type causes all
types to be displayed. All packet types are displayed by default.
RESET
resets the filter options to their default values.
SDN [ subdevice-number ]
displays level-4 entries and packets and level-3 state-machine entries for the
specified subdevice number (entered in decimal notation). Omitting subdevice-
number turns off filtering based on SDN. By default, filtering by subdevice number
is off.
Considerations
•
FILTER LCN 0 finds restart packets; FILTER SDN 0 finds incoming call-request
packets.
•
FILTER PACKET CALL displays both incoming and outgoing call-request and call-
accept packets.
•
While both LCN and SDN filtering can be in effect at the same time, only a few
combinations make sense. This filter command displays restarts and SDN xx:
? FILTER LCN 0; FILTER SDN xx
The following filter command displays restarts and incoming calls:
? FILTER LCN 0; FILTER SDN 0
•
Filter options require a corresponding select mask. For example, the restart
packets are level-3 data. To display only restart packets, you must issue the
SELECT L3 and FILTER PACKET RESTART commands.
SELECT Command
The SELECT command establishes the selection criteria that control which trace
records you want to display. To determine which records to display in response to a
NEXT, FIND, or RECORD command, PTrace checks its selection mask to determine
whether the record is a type that you want to display. PTrace also checks many other
session parameters, such as those established by the FILTER and LIMIT commands.
