Port-Limit
The default limit (in bytes) of all unacknowledged transmit messages to
terminals on a port. This parameter controls how much outbound data is
allowed onto the ACC card for each port. Each port has 24,000 bytes of
memory available for outbound data buffers (including protocol packets).
This parameter is used to prevent the host from exceeding the available
memory on the card, thereby causing the host to retry the
transaction.The recommended value is 20,000 bytes. It must be less than
24,000 bytes.
Note that you may override this global value on a port-by-port basis by
using the Port-Limit parameter in the Port-Definition section.
