Frame Settings
Description
Frame settings are configured using two menu items:
z Frame level disconnect—Specifies the level at which a disconnect frame is sent.
The following options are available:
z Active—Acknowledges that a link is disconnected when a disconnect frame
(DISC) is sent and an unnumbered acknowledgment (UA) is received. Some
systems do not acknowledge the DISC frame with a UA but send a set
asynchronous balanced mode frame (SABM) instead. To bring this link up, the
system must be configured for a passive disconnect. If a remote system fails
to respond to a receive ready (RR) frame enough times to exceed the
maximum number of accepted retransmissions for unacknowledged frames
(described in section N2 Retry Counter on page 6-50
), then AI296 sends
DISC frames continuously.
z Passive—Specifies that the DISC frame is not sent. AI296 responds to an
SABM with a UA. If a remote system fails to respond to an RR frame enough
times to exceed the maximum number of accepted retransmissions for
unacknowledged frames, then AI296 sends SABM frames continuously.
z Other—Specifies that an immediate disconnect frame (DISC) is sent if an RR
has been sent enough times to exceed the maximum number of accepted
retransmissions for unacknowledged frames and no reply has been received.
