"This table contains objects that can be
changed to manage an SDLC port. Changing one
of these parameters may take effect in the
operating port immediately or may wait until
the interface is restarted depending on the
details of the implementation.
Most of the objects in this read-write table
have corresponding read-only objects in the
sdlcPortOperTable that return the current
operating value.
The operating values may be different from
these configured values if a configured
parameter was changed after the interface was
started."

implementation-specific significance. Its value
shall be unique within the administered

accept a write operation for this object, it
causes the logical port definition associated

sdlcLSAdminREPLYTO OBJECT-TYPE
SYNTAX TimeInterval
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"This object controls the reply timeout (in
1/100ths of a second) for an SDLC link
station. If the link station does not receive
a response to a poll or message before the
specified time expires then the appropriate
error recovery shall be initiated.
The object descriptor contains the name of an
NCP configuration parameter, REPLYTO. Please
note that the value of this object represents
1/100ths of a second while the NCP REPLYTO is
represented in 1/10ths of a second.
Depending on the implementation, a write
operation to this administered value may not
change the operational value, sdlcLSOperREPLYTO,
until the link station is cycled inactive.
This object only has meaning for SDLC ports
where sdlcPortAdminRole == primary "

DESCRIPTION
"This object controls the maximum number of
unacknowledged I-frames which an SDLC link
station may receive. This should range from 1
to (sdlcLSAdminMODULO - 1). This value is sent

For link stations on switched SDLC lines,
certain implementions may choose to override
this administered value with the value
received in the XID exchange.
Depending on the implementation, a write

change the operational value,

"This object controls number of retries in a

retransmitted frames ( data or control) for
which no positive acknowledgement is received.
The number of times that the retry sequence is
to be repeated is controlled by the object:
sdlcLSAdminRETRIESn. The interval between retry
sequences is controlled by the object:
sdlcLSAdminRETRIESt.
A value of zero indicates no retries. If the
value of sdlcLSAdminRETRIESm is zero, then the
values of sdlcLSAdminRETRIESt and
sdlcLSAdminRETRIESn should also be zero.
Depending on the implementation, a write
operation to this administered value may not
change the operational value,

is received.
The number of repeated retries sequences is
controlled by the object: sdlcLSAdminRETRIESn.
The retries per sequence is controlled by the
object: sdlcLSAdminRETRIESm.
The object descriptor contains the name of an
