HP-UX SNAplus2 R7 NOF Programmer's Guide

NOF API Verbs
DEFINE_PORT
AP_LS_TWA
Two-way alternating
For Enterprise Extender (HPR/IP), this parameter must be set to AP_LS_TWS.
def_data.max_ifrm_rcvd
Maximum number of I-frames that can be received by the local link stations before an acknowledgment is
sent. Range: 1–127.
def_data.target_pacing_count
Numeric value between 1 and 32,767 inclusive indicating the desired pacing window size. (The current
version of SNAplus2 does not make use of this value.)
def_data.max_send_btu_size
Maximum BTU size that can be sent from this port. 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.dlc_data.format
The type of link address specified for this port. Possible values:
AP_IP_ADDRESS_INFO
IP address. Specify this value for an Enterprise Extender (HPR/IP) port.
AP_UNSPECIFIED
Unspecified address format. Specify this value for any port type other than Enterprise Extender (HPR/
IP).
def_data.dlc_data.length
Length of the port address (in the following parameter).
def_data.dlc_data.address
Port address.
For Enterprise Extender (HPR/IP), this parameter is reserved. Instead, you specify the port address using the
local_ip_interface parameter in the port-specific data.
For SDLC, this is a 1-byte address. If ls_role is set to AP_LS_SEC,orifls_role is set to AP_LS_NEG
and the local station becomes secondary after LS role negotiation, this address is used in the response to an
incoming call. If the local station is primary, or if the port is used only for outgoing calls, this parameter is
reserved.
For QLLC, this is a string of 1–14 bytes, specifying the local X.25 DTE address of the port. This address
must match the address configured in your X.25 driver for this network.
Note
If no address is specified on a QLLC port, an outgoing call request generated by
SNAplus2 will not contain the X.25 calling address. Some hosts require this address
as a security measure on incoming calls, and may not accept the connection without
it.
def_data.dlc_data.tr_address.lsap_address
For Token Ring, Ethernet, or FDDI: Local SAP address of the port. Specify a multiple of 0x04 in the range
0x04–0xEC. The value must be specified as two hexadecimal digits preceded by 0x.
