Module: CXX25-MIB

OID (symbolic): CXX25-MIB::x25SapTxPacketSize

OID (numeric): 1.3.6.1.4.1.495.2.1.6.29.21.1.33

Node type: OBJECT-TYPE

Type: PacketSize

Access: read-write

Description: Determines the default transmit packet 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.

Options: bytes16 (4)

bytes32 (5)

bytes64 (6)

bytes128 (7)

bytes256 (8)

bytes512 (9)

What is x25SapTxPacketSize?

Sets this SAP's default transmit packet size (16-4096 bytes, default 128), applied when flow-control negotiation isn't subscribed to or on D-bit calls, mirroring x25SapRxPacketSize for the outbound direction. An admin tunes this alongside the receive size to balance throughput against buffering/latency on the X.25 link.

Examples
