ADD Command
each opener that has a read request posted. The default is parallel. This attribute is
not supported for token-ring LLC1 ports.
ZMAX-REQ-SIZE
is the maximum size (in bytes) of a block of messages that can be written and read
by the port. This value cannot be larger than the LINE’s MAXREQUESTSIZE. The
minimum value that must be specified in this field is 49 bytes for LLC1-type ports
and 32 bytes for Ethernet-type ports. The default value is 32000 bytes.
ZDATA-FWD-TIME
is the maximum amount of time that an inbound message should wait before it is
delivered (data forward time). The waiting time is expressed in microseconds. The
valid input range is 100000 through 60000000 microseconds (0.1 second through 60
seconds); however, the resolution is in milliseconds and the last three digits are
truncated. The default value (-1) sets the data forward time to INFINITE, which
means that an inbound message will wait forever, if necessary, to be delivered.
Note that the delivery of inbound messages is also triggered when the number of
messages present in the receive queue equals the data forward count (ZDATA-FWD-
CNT) value described below, regardless of the amount of time elapsed.
ZDATA-FWD-CNT
is the maximum number of inbound messages that should be queued before they are
delivered (data forward count). The valid range is 1 through 22 messages. The
default value is 1 message.
Note that the delivery of inbound messages is also triggered when the elapsed time
since the receipt of the first message equals the data forward time (ZDATA-FWD-
TIME) value described above, regardless of the number of messages received.
ZLLC2-ENABLED
allows the port to send and receive LLC2 frames. The implementation of the LLC2
protocol stack is the responsibility of the application. The ZLLC2-ENABLED token
is valid for LLC1 ports types only.
Tokens in Response Buffer
The tokens present in the buffer received in response to an ADD command are described
in Section 4, Common Definitions.
Operational Notes
There are several things you should remember when using the ADD PORT command:
•
The PORT object requires that you specify an appropriate object subtype in the
ZPAM-TKN-OBJ-SUBTYPE token. The valid object subtype values are
ZPAM-VAL-PORT-TYPE-ENET
ZPAM-VAL-PORT-TYPE-LLC1
