NOF API Verbs
DEFINE_LS
def_data.max_send_btu_size
Maximum BTU size that can be sent from this link station. This value is used to negotiate the maximum
BTU size that a pair of link stations can use to communicate with each other. The value includes the length
of the TH and RH (total 9 bytes) as well as the RU. Specify a value in the range
265–65535 (265–4105
for SDLC).
def_data.ls_role
Link station role. This is normally set to AP_USE_PORT_DEFAULTS, specifying that the LS role is to be
taken from the definition of the port that owns this LS.
If you need to override the port’s LS role for an individual LS, specify one of the following values:
AP_LS_PRI
Primary
AP_LS_SEC
Secondary
AP_LS_NEG
Negotiable
For an Enterprise Extender (HPR/IP) port, you must use AP_USE_PORT_DEFAULTS; you cannot override
the port’s LS role.
def_data.max_ifrm_rcvd
The maximum number of I-frames that can be received by this link station before an acknowledgment is sent.
Specify a value in the range 0–127.If0 is specified, the value from the port definition is used.
def_data.dlus_retry_timeout
For an Enterprise Extender (HPR/IP) port, this parameter is reserved.
Reactivation timer for contacting a DLUS. If SNAplus2 fails to contact the DLUS, this parameter specifies
the time in seconds between retries.
Specify a value in the range 0x0001–0xFFFF.
def_data.dlus_retry_limit
For an Enterprise Extender (HPR/IP) port, this parameter is reserved.
The interval in seconds between the second and subsequent attempts to contact the DLUS specified by the
dlus_name and bkup_dlus_name parameters. Specify a value in the range 0x0001–0xFFFE, or specify
0xFFFF to indicate that SNAplus2 should retry indefinitely until it contacts the DLUS. The interval between
the first and second attempts is always 1 second. If zero is specified, then the defaults specified using the
DEFINE_DLUR_DEFAULTS verb are used. This parameter is ignored if the dspu_services parameter is not
set to AP_DLUR.
def_data.branch_link_type
This parameter applies only if the local node is a Branch Network Node; it is reserved if the local node is
any other type.
If the parameter def_data.adj_cp_type is set to AP_NETWORK_NODE, AP_END_NODE, AP_APPN_NODE,or
AP_BACK_LEVEL_LEN_NODE, this parameter defines whether the link is an uplink or a downlink. Possible
values are:
AP_UPLINK
The link is an uplink.
AP_DOWNLINK
