making an even number of digits. NSAP values are administered by a
central addressing authority. See the considerations for the ADD SU
command (concerning protocol selection) for information on when to use this
attribute. To reset this field to its default value set the first byte to ZOS4-VAL-
ADDR-RESET-BYTE.
ZSEND-SECUR
specifies the content of the protection field for CR-TPDUs and CC-TPDUs. If
you do not provide a value, the protection field is omitted. Note that not all
transport protocol implementations support this attribute. This parameter
applies to transport classes 1, 2, 3, and 4 only. This value is an ASCII string up
to 16 characters long. To reset this field to its default value, set the first byte to
ZOS4-VAL-SECUR-RESET-BYTE.
ZRECV-SECUR
specifies whether security checking is performed on incoming CR-TPDUs. If
security checking is specified, only incoming CR-TPDUs that have matching
characters in the protection field are accepted. If you do not provide a value,
no security checking is performed. This attribute is valid only when ZCLASS
is ZOS4-VAL-CLASS-1, ZOS4-VAL-CLASS-2, ZOS4-VAL-CLASS-3, or ZOS4-
VAL-CLASS-4. Note that not all transport protocol implementations support
this attribute. This value is an ASCII string up to 16 characters long. To reset
this field to its default value, set the first byte to ZOS4-VAL-SECUR-RESET-
BYTE.
ZLAN-LOC-SNPA
is the local area network (LAN) subnetwork address. This address is a
hexadecimal string (0-9 and A-F) up to 14 digits long and 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. This string should
contain an even number of hexadecimal digits. If you supply an odd number
of digits, a hexadecimal “F” is added to the end, making an even number of
digits. To obtain this value, issue an INFO SERVICE command with a ZCOM-
TKN-OBJNAME value of $lan-device-name.#L18023. See the considerations for
the ADD SU command (concerning protocol selection) for information on
when to use this attribute. To reset this field to its default value, set the first
byte to ZOS4-VAL-ADDR-RESET-BYTE.
ZLAN-RMT-SNPA
is the remote LAN subnetwork address. This address is a hexadecimal string
(0-9 and A-F) up to 14 digits long and 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
