Timer wait for a command before initiating
recovery action. This is used when
the Link is secondary. The default is
30.

BLUs that can be sent to the second-
ary Station before starting data
transmission to the next Station in
the Link service order table. This is
used when the Link is Primary. The
default is 1.
Select (1-60000) Displays time (in milliseconds) to
Pause pause before sending a response with
the final bit set. This is used when
the LINK is secondary. The default
is 50.
Retry (0-255) Displays the time (in seconds) to
Sequence pause after completing a retry sequ-
Pause ence before beginning a new retry
sequence. This is used when the
Link is primary. The default is 0.
Not used at this time.
Retry (0-127) Displays the maximum number of
Sequence retry sequences allowed. This is used
Limit when the Link is primary. The
default is 0. Not used at this time.
Immediate no | yes Displays whether a Station
Poll subentity will be repolled when there
Retry is a reply time-out before proceeding
to next Station on the Link's service
order table. The default is no.

6 – Port Subentity
For each Enabled Station that establishes a connection, SDLC creates a Port entity.
6.1 – show
show sdlc port The show sdlc port command displays the attributes for the SDLC Port subentity. A Port subentity is created dynamically for each connection to a remote station. Each Port is created when a connection is established and deleted when the connection is terminated. Use the command show sdlc port * to display a listing of the existing Ports. Ex, ncl> show sdlc port 1 all counters

before this station requires an acknowledgment
response. The value is initialized as the SDLC
Station Window Size and might be reduced
