o buffers temporarily unavailable
Number of times the local station could not service messages
from the remote station because there were no receive buffers
available.
o buffers too small
Number of times the local station could not service messages from
the remote station because the receive buffers were not large
enough.
o creation time
Time at which this entity was created.
o incomplete replies to select
Specifies the number of selection intervals that were not
properly terminated (that is, by a message with the Select bit
set in the header), during which a transmission was received or
an attempt at transmission was detected.
This counter is supported only if the protocol characteristic of
the owning ddcmp link entity is set to control, or when the link
is a half-duplex point-to-point link.
o local reply timeouts
Number of times the local station failed to receive an
acknowledgment before the reply timer expired.
o locally initiated state changes
Number of times that the station protocol state changed through
action of the local station.
o naks received indicating buffer too small
Number of times the remote station reported that it could not
service a message because the receive buffer was not large
enough.
o naks received indicating buffers temporarily unavailable
Number of times the remote station reported that it could not
service a message because no receive buffer was available.
o naks received indicating data field block check error
Number of times the remote station reported that a block check
error was detected in the data field of an incoming message.
o naks received indicating header block check error
Number of times the remote station reported that a block check
error was detected in the header block of an incoming message.
o naks received indicating rep response
Number of times the remote station reported that it did not
receive all the messages sent from the local station.
o naks sent with rep response
Number of times that the local station detected that not all
of the messages sent from the remote station were received
correctly.
o no replies to select
Specifies the number of times that the select timer expired for
any of the following reasons:
o No valid control message was received.
o No valid header to a data message was received.
o No valid header to a maintenance message from the selected
station was received.
o No transmission from the remote station was received.
This counter is supported only if the protocol characteristic of
the owning ddcmp link entity is set to control, or when the link
is a half-duplex point-to-point link.
o pdus received with data field check block error
Number of messages received with a check error in the data field.
o pdus received with header block check error
Number of messages received with a check error in the header
block.
o receive error thresholds reached
Number of times that the receive error threshold has been
reached.
o remote reply timeouts
Number of times the local station received a REP message and
sent an acknowledgment in return. This sequence indicates that
all messages sent from the remote station have been correctly
received.
o remotely initiated state changes
Number of changes in the station protocol state caused by action
of the remote station.
o sdu octets received
Number of data octets received from the remote station.
o sdu octets sent
Number of data octets sent to the remote station.
o sdus received
Number of data messages received from the remote station (not
including retransmissions).
o sdus sent
Number of data messages sent to the remote station (not including
retransmissions).
o selection error thresholds reached
Number of times that the selection error threshold has been
reached.
This counter is not supported if the characteristic protocol of
the owning ddcmp link entity is set to tributary.
o selection intervals
Number of times that the local station selected the remote or a
tributary station. The counter does not appear if the link uses
the tributary protocol. In addition, the counter appears only
when the local station is the control station for a number of
tributaries, or is operating over a half-duplex point-to-point
link.
This counter is supported only if the protocol characteristic of
the owning ddcmp link entity is set to control, or when the link
is a half-duplex point-to-point link.
o send error thresholds reached
Number of times that the send error threshold has been reached.
o strts received while in maintenance
Number of times that the local station received a STRT protocol
message while in the Maintenance state.
