bscCuMaxBlockLength

Module: CXBsc-MIB

OID (symbolic): CXBsc-MIB::bscCuMaxBlockLength

OID (numeric): 1.3.6.1.4.1.495.2.1.6.56.11.1.5

Node type: OBJECT-TYPE

Type: BscBlockSize

Access: read-write

Description: Identifies the maximal length of the blocks exchanged between the host/terminal and the BSC module. The value is measured in octets and is specified by the BSC protocol. The DEFVAL value will be 'block3000' or 'block256', depending if the sap is configurated as 'hostInterfaceUnit' or 'terminalInterfaceUnit' (see the object 'bscSapInterfaceType').

What is bscCuMaxBlockLength?

This read-write value sets the maximum block size, in octets, exchanged between the host/terminal and the BSC module for this controller unit, defaulting to 'block256' or 'block3000' depending on whether the owning SAP is a host or terminal interface. An admin raises or lowers this to match the buffering capability of the attached 3270 controller and avoid triggering bscSapBlockReject on the other end.
