SIBCHECK analyzes important fields and relevant status
flags in an SIB and related control blocks. The following control
blocks are analyzed:
- DLU cross-network extension (SIBX)
- OLU cross-network extension (SIBX)
- PLU resource extension (SIBRX)
- SIB base
- SIB initiation extension (SIBIX)
- SLU resource extension (SIBRX)
- SIB termination extension
SIBCHECK determines:
- Alias resource names and network IDs
- Configuration (cross-domain, cross-network, back-to-back, and
so on)
- Destination logical unit
- GWNCP names
- Initiating logical unit
- Network addresses
- Originating logical unit
- Primary logical unit
- RDTE address
- Real resource names and network IDs
- Resource type (APPL, LU, CDRSC, and so on)
- Secondary logical unit
For each status bit in the SIB and related control blocks,
the bit name, its value, and its meaning (from )
are listed.
Fields in the SIB that contain addresses are checked
(such as SIBTV35P, the CV35 pointer, or SIBTNOTP, the pointer to NOTIFY
RU). If these fields contain a nonzero address, the address and description
of the field are also displayed.
Note: The SIBBTIME value is
displayed in the format of coordinated universal time (formerly
known as Greenwich Mean Time).
Operands
You must specify one address or
one symbol.
- Address
- Enter 1–8 hexadecimal digits in the form X'x…' for the
address of the SIB to be analyzed. If the address is fewer than 8
digits, it is padded on the left with zeros.
- IPCS symbol
- Enter 1–31 alphanumeric characters for an IPCS symbol name that
has been previously equated with the address of the SIB to be analyzed.
Do not include a period.
Under IPCS, the symbol X represents the
address currently being displayed. If the current address is an SIB,
this symbol may be used to refer to it.
Use the following syntax as an alternative
to the panel interface.
