INFO PORT Command
ZDELIV-MODE
determines how read requests are queued. If ZPAM-VAL-DELIV-MODE-SRL
(serial mode, which is the default mode) is selected, all read requests are placed in a
single queue and are serviced in FIFO (first in first out) order. If ZPAM-VAL-
DELIV-MODE-PLLEL (parallel mode) is selected, all read requests are placed in
separate queues, one for each opener of the port. Inbound messages are delivered to
each opener that has a read request posted. 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 32 bytes for LLC1-type ports
and 49 bytes for Ethernet-type ports. The default value is 32767 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 .001 second through 60 seconds. 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.
ZMAX-SESS
specifies the maximum number of sessions that can be configured under this port.
This attribute is valid only for LLC2 ports.
