NOF API Verbs
DEFINE_PORT
Implicit links to an End Node are uplinks.
AP_NO
Implicit links to an End Node are downlinks.
def_data.port_number
The number of the port.
For Enterprise Extender (HPR/IP), this parameter is reserved.
def_data.max_rcv_btu_size
Maximum BTU size that can be received. 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.tot_link_act_lim
Total link activation limit (the maximum number of links that can be active at any time using this port).
For an SDLC port with
port_type set to AP_NONSWITCHED and ls_role set to AP_LS_PRIor AP_LS_SEC,
the range is 1–256 (a value greater than 1 defines a multi-drop primary link or a multi-PU secondary link).
For all other SDLC ports, this parameter must be set to 1.
def_data.inb_link_act_lim
Inbound link activation limit (the number of links reserved for inbound activation). The sum of
inb_link_act_lim and out_link_act_lim must not exceed tot_link_act_lim; the difference between
inb_link_act_lim and tot_link_act_lim defines the maximum number of links that can be activated outbound
at any time.
For an SDLC port with port_type set to AP_NONSWITCHED, this parameter must be zero. If port_type is set
to AP_SWITCHED, then the port must be defined to accept either incoming calls (inb_link_act_lim = 1 and
out_link_act_lim = 0) or outgoing calls (inb_link_act_lim = 0 and out_link_act_lim = 1).
def_data.out_link_act_lim
Outbound link activation limit (the number of links reserved for outbound activation). The sum
of inb_link_act_lim and out_link_act_lim must not exceed tot_link_act_lim; the difference between
out_link_act_lim and tot_link_act_lim defines the maximum number of links that can be activated inbound
at any time.
For an SDLC port with port_type set to AP_NONSWITCHED, this parameter must be equal to tot_link_act_lim.
If port_type is set to AP_SWITCHED, then the port must be defined to accept either incoming calls
(inb_link_act_lim = 1 and out_link_act_lim = 0) or outgoing calls (inb_link_act_lim = 0 and out_link_act_lim
=1).
def_data.ls_role
Link station role.
For SDLC or QLLC, the following values are allowed:
AP_LS_PRI
Primary
AP_LS_SEC
Secondary
AP_LS_NEG
Negotiable
For Token Ring / Ethernet / FDDI/ Enterprise Extender (HPR/IP), this must be set to AP_LS_NEG.
def_data.implicit_dspu_template
