An NSAP entry-name identifies a network service access point (NSAP). It is used to
configure a TSP server process for a local NSAP, as well as the subnetwork point of
attachment (SNPA) for both local and remote NSAPs. NSAP ENTRY objects make up
the routing table for the OSI end system. An NSAP entry-name is a string of
hexadecimal digits. Its maximum length is 40 hexadecimal digits (20 octets). For LAN
networks only, this string must contain an even number of hexadecimal digits.
An SNPA entry-name identifies a local subnetwork point of attachment (SNPA) and
is used to configure an NSP server process for that local SNPA. An SNPA ENTRY
name is a string of an even number of hexadecimal digits. Its maximum length is 16
hexadecimal digits (8 octets). For X25AM subnetworks, the rightmost two digits are
used for the port number. In X.25-1984 mode, the rest of the name is the X.25 DTE
address; in X.25-1980 mode, the rest of the name is an internal index number. For
TLAM subnetworks, the leftmost two digits must be FE, and the rest of the name is the
media access control (MAC) address of the TLAM process.
A TSEL entry-name identifies a local transport selector (TSEL) and is used to
configure a TAPS server process for this specific local TSEL. A TSEL entry˚name is a
string of an even number of hexadecimal digits. Its maximum length is 64
hexadecimal digits (32 octets).
Wild-Card Support
Wild cards are supported for the DELETE ENTRY, INFO ENTRY, and LISTOBJECTS
ENTRY commands. You can specify wild cards in the #entry-type or entry-name
fields. Examples of the #entry-type and entry-name fields with wild cards are:
.*.E*
.#*.E*
.#A*.*
.#SNPA.FE*
.#TSEL.000?
Examples
$OSIM.#APPL.USER1
$OSIM.#NSAP.9A0002
$OSIM.#NSAP.9A00??
$OSIM.#SNPA.FE08008E000023
$OSIM.#TSEL.0001
$OSIM.#TSEL.*
ZCOM-OBJ-NULL
ZCOM-OBJ-NULL does not represent an actual OSI/AS object type. It is used as the
object type in commands that do not require specification of a particular object type.
Only two OSI/AS commands—GETVERSION and LISTOBJECTS—accept the null
object type.
