lapbdDlSapWindowSize
Module: CXLapBD-MIB
OID (symbolic): CXLapBD-MIB::lapbdDlSapWindowSize
OID (numeric): 1.3.6.1.4.1.495.2.1.6.27.21.1.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Determines the maximum number of information frames that can be outstanding at any given time (window size). A frame is considered to be outstanding until the other side acknowledges its receipt. This object supports modulo 8 and modulo 128 service.
Setting lapbdMacSapLapbProtocolFlavour to 'v8022' forces lapbdDlSapModulo to 'modulo 128', which affects the maximum setting that can be made to this object.
Range of Values:
1 - 7 if object lapbdDlSapModulo is set to modulo8
1 - 127 if object lapbdDlSapModulo is set to modulo128
Default Value: LAPB = 7, LAPD = 7
Related Objects: lapbdDlSapModulo lapbdMacSapLapbProtocolFlavour
Configuration Changed: administrative and operative
What is lapbdDlSapWindowSize?
Sets how many unacknowledged information frames may be outstanding on this data-link connection at once, up to 7 under modulo-8 numbering or up to 127 under modulo-128 (chosen via lapbdDlSapModulo); raising it from the default of 7 can improve throughput on high-latency links at the cost of more buffering.
