Description
The SHOW PORTS command provides port-independent information from the
port descriptor table (PDT) for those CI ports with full SCS connections. This
information is used by all system communications services (SCS) port drivers.
Note that the SHOW PORTS command does not display similar information
about UDA ports, BDA ports, and similar controllers.
The SHOW PORTS command also defines symbols for PEDRIVER based on the
cluster configuration. These symbols include the following information:
• Virtual circuit (VC) control blocks for each of the remote systems
10
You can find the pdt-address for any active connection on the system in the PDT
summary page display of the SHOW PORTS command. This command also defines
the symbol PE_PDT. CDT addresses are also stored in many individual data structures
related to SCS connections; for instance, in the path block displays of the SHOW
CLUSTER/SCS command.
