ALTER SU Command
Value: ON | OFF
L4WINDOW
specifies the maximum credit allocation to the remote transport entity. This is the
number of TPDUs that can be sent by the remote transport entity without
acknowledgment. This attribute is valid only when the transport protocol class is 1,
2, 3, or 4, but see below, because this attribute performs differently when the
transport protocol class is 1.
Value: 0 through 15
When the transport protocol class is 1, L4WINDOW must be 0 or 1 (a value of 0 is
interpreted as 1). For transport class 1, the use of values 2 through 15 could lead to
a deadlock situation when the sending transport entity waits for the acknowledgment
of each DT-TPDU before it sends the next one.
LANLOCALSNPA
LANLOCALSNPA is the local area network (LAN) subnetwork address. This value
is automatically obtained by the TSP process during the first transport connection
attempt over the specified device. LANLOCALSNPA is made up of two
components. The first two hexadecimal digits are the link-level service access point
selector (LSAP selector or LSEL); for OSI/TS, this value must be “FE.” The
remaining 12 digits are the media access control (MAC) address. The MAC address
specifies the local LAN station address.
See the considerations for the ADD command (concerning protocol selection) for
information on when to use this attribute.
RESET returns this attribute to the default value (no address specified).
Value: A hexadecimal string (0-9 and A-F) up to 14 digits long. It must begin with
the digits “FE” This string should contain an even number of hexadecimal digits.
This value is automatically obtained by the TSP process as described above.
LANREMOTESNPA
is the remote LAN subnetwork address. This address is made up of two
components. The first two hexadecimal digits are the link-level service access point
selector (LSAP selector or LSEL); for OSI/TS, this value must be “FE.” The
remaining 12 digits are the MAC address. The MAC address specifies the remote
LAN station address.
See the considerations for the ADD command (concerning protocol selection) for
information on when to use this attribute.
RESET returns this attribute to the default value.
Value: A hexadecimal string (0-9 and A-F) up to 14 digits long. It must begin with
the digits “FE” This string should contain an even number of hexadecimal digits. If
an odd number of digits is supplied, a hexadecimal “F” is added to the end, making
an even number of digits.
