x25SapRxWindowSize

Module: CXX25-MIB

OID (symbolic): CXX25-MIB::x25SapRxWindowSize

OID (numeric): 1.3.6.1.4.1.495.2.1.6.29.21.1.34

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Determines the default receive window size used by this SAP. This value is used only when flow control negotiation (x25SapSbscrFlowCntrlParamNegotiation) is not subscribed to, or when a D-bit call is routed through this SAP.

Range of Values: 1 - 7 for modulo 8

1 - 127 for modulo 128

Default Value: 2

Related Objects: x25SapSbscrFlowCntrlParamNegotiation x25SapModulo

Configuration Changed: administrative and operative

What is x25SapRxWindowSize?

Sets this SAP's default receive window size (1-7 under modulo 8, or 1-127 under modulo 128; default 2), the number of unacknowledged packets the SAP can accept before it must send an acknowledgment, applied when flow control isn't negotiated or on D-bit calls. An admin raises this alongside x25SapTxWindowSize to allow more data in flight on higher-latency links, bounded by the modulo selected in x25SapModulo.
