• !* for no display.
• !Qsaal or !Q93b to not display QSAAL or Q93b, respectively.
Use QSAAL for signalling PDUs without Q93b information. Use Q93b for
signalling PDUs encapsulating Q93b information.
VC Filter Options
Circuit filter options are used to include or exclude trace records of
circuit traffic filtered for VPIs and VCIs. Filtering on the VPIs and VCIs
is specified as follows:
atm VPI argument [ argument ] ...
atm VCI argument [ argument ] ...
where argument is one of the following:
• * for all.
• !* for none.
• A numeric value (for example, 32).
• A range (for example, 0-32).
Up to 10 argument s can be specified.
VPI/VCI filtering is active for only the following:
• IP/ARP packets.
• Direct access packets (AAL).
• LAN Emulation packets.
Call Reference Filter Options
Because signalling traffic is important, call reference filtering for Q93b is
provided. This allows the formatter to trace a single or grouped
connection management dialog. The syntax is as follows:
atm CallRef argument [ argument ] ...
where argument is one of the following:
• * for all.
• !* for none.
• A numeric value (for example, 128).
