x25SapRxPacketSize

Module: CXX25-MIB

OID (symbolic): CXX25-MIB::x25SapRxPacketSize

OID (numeric): 1.3.6.1.4.1.495.2.1.6.29.21.1.32

Node type: OBJECT-TYPE

Type: PacketSize

Access: read-write

Description: Determines the default receive 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)

bytes1024 (10)

Configuration Changed: administrative and operative

What is x25SapRxPacketSize?

Sets this SAP's default receive packet size (from 16 to 4096 bytes in powers of two, default 128 bytes), used whenever flow-control-parameter negotiation isn't subscribed to or a D-bit call is routed through the SAP. An admin raises this (e.g. to bytes1024) to improve throughput on high-bandwidth links, working alongside x25SapTxPacketSize and x25SapSbscrFlowCntrlParamNegotiation.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.495.2.1.6.29.21.1.32
snmpwalk -v2c -c public <target> CXX25-MIB::x25SapRxPacketSize

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.495.2.1.6.29.21.1.32.1
snmpget -v2c -c public <target> CXX25-MIB::x25SapRxPacketSize.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.495.2.1.6.29.21.1.32.1 s <value>
