Configuring Optional Sdlc Parameters - 3Com MSR 50 Series Configuration Manual

Configuring Optional
SDLC Parameters
To do...
Enter system view
Enter interface view
Configure the baud rate of the
synchronous serial interface
Configure the synchronous serial
interface to use NRZI encoding
Configure the synchronous serial
interface to send 0xFF (marks)
during idle state
Generally it is not required to change the idle-time encoding scheme of a
synchronous serial interface, except when the synchronous serial interface is
connected to an AS/400 device.
Follow these steps to configure optional SDLC parameters:
To do...
Enter system view
Enter interface view
Configure the length of SDLC
output queue
Configure the maximum
number of consecutive frames
the device can send before
receiving an
acknowledgement from the
peer
Configure the modulus value
of SDLC
Configure the maximum
SDLC PDU size
Configure the maximum
number of SDLC transmission
retries
Configure the local and
remote SAP addresses for
SDLC-to-LLC2 frame
conversion

Optional
265 bytes by default
The maximum PDU size of
some PU2.0 devices is 265
bytes, while that of an IBM
AS/400 is 521 bytes. Typically,
this maximum PDU size
should be configured be the
same as on the peer SDLC
device.
