x25SapModulo

Module: CXX25-MIB

OID (symbolic): CXX25-MIB::x25SapModulo

OID (numeric): 1.3.6.1.4.1.495.2.1.6.29.21.1.31

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This object applies only to lower SAPs (service access points).

Determines the range of sequence numbers available for packet numbering at this SAP (service access point). The modulo specified for this object must match that specified on the destination SAP for a route to be successful. If not, this SAP will refuse the call.

Options: modulo8 (1): Sequence numbers range from 0 to 7, supporting a maximum window size of 8.

modulo128 (2): Sequence numbers range from 0 to 128, supporting a maximum window size of 128

Default Value: modulo8 (1)

Related Objects: x25SapRxWindowSize x25SapTxWindowSize x25PvcRxWindow x25PvcTxWindow

Configuration Changed: administrative

What is x25SapModulo?

Selects the packet sequence-numbering range for this lower SAP: modulo8(1), the default, allows sequence numbers 0-7 (window up to 8), while modulo128(2) allows 0-127 (window up to 128) for higher-throughput links. The modulo configured here must match the destination SAP's setting or the call is refused, and it directly bounds the legal range for x25SapRxWindowSize/x25SapTxWindowSize.
