RNRRECEIVE
RETRIES and TIMEOUT work together and should be specified with values dependent
upon the specification of RETRIES in the LINE or PU definition statements that define
the HP NonStop entities in the host’s NCP system generation. Specify a RETRIES
value so that when it is multiplied by TIMEOUT (in seconds), the product is greater
than that produced by multiplying the “t” and “n” values specified in the RETRIES
operand in the host’s NCP system generation. These restrictions ensure that in the
event of line hits or temporary hardware failures, the SNAX/XF T1 timer does not time
out before the host retries a failed transmission and that SNAX/XF does not declare a
loss of communication before the host declares a loss of communication with
SNAX/XF.
RNRRECEIVE
RNRRECEIVE specifies how the local station handles Receiver Not Ready (RNR)
frames received from a remote station. This attribute applies only to line type 58,5
(SDLC).
ON indicates that, upon receiving an RNR frame, the local station examines the value
specified for the RNRTIMER and determines the action to be taken. If RNRTIMER has
the value of 0, SNAX/XF allows the receive RNR state to persist indefinitely.
Otherwise, SNAX/XF tries to resend I-frames, up to the number of times indicated by
RETRIES, as long as RNRTIMER does not expire.
OFF indicates that, upon receiving an RNR frame, the local station sends a disconnect
(DISC) command, if it is the primary station, or a frame reject (FRMR) command, if it is
the secondary station, and enters a Logical Disconnected State (LDS).
RNRSEND
RNRSEND specifies whether the local station sends Receiver Not Ready (RNR)
frames to a remote station when it is in a buffer-depletion state. This attribute applies
only to line type 58,5 (SDLC).
ON indicates that the local station continues to send RNR frames to the remote station
until the RNR state is cleared by the release of buffer space or until the RNR timer
expires. If RNRTIMER has a value of 0 (zero), SNAX/XF allows the RNR state to
persist indefinitely.
OFF indicates that, when it enters RNR state, the local station sends a disconnect
(DISC) command if it is the primary station. If it is the secondary station, it sends a
