x25SapFlowControlTimer
Module: CXX25-MIB
OID (symbolic): CXX25-MIB::x25SapFlowControlTimer
OID (numeric): 1.3.6.1.4.1.495.2.1.6.29.21.1.68
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object applies only to lower SAPs (service access points).
Determines the amount of time between checks of available system resources when the virtual circuits at this SAP have entered flow control. Flow control is initiated when system resources have fallen below the threshold specified by object x25LowerPoolThreshold.
This timer is started when flow control is initiated, and when it expires, system resources are rechecked. If resources have risen above x25UpperPoolThreshold, flow control is terminated (a packet-level RR is issued on the affected virtual circuit), otherwise the timer is restarted.
Packet level RNR/RR are only issued for virtual circuits on lower SAPs. Virtual circuits on upper SAPs issue internal flow control messages.
This is a global setting that applies to all virtual circuits established at this SAP.
Range of Values: 1 - 300 seconds
Default Value: 10 seconds
Related Objects: x25LowerPoolThreshold x25UpperPoolThreshold
Configuration Changed: administrative and operative
What is x25SapFlowControlTimer?
For lower SAPs only, sets (1-300 seconds, default 10) how often this SAP rechecks overall system resources while its virtual circuits are under flow control (triggered when resources drop below x25LowerPoolThreshold); once resources recover above x25UpperPoolThreshold, flow control is lifted (an RR is sent) and the affected circuits resume normal data flow. An admin shortens this interval to recover from transient resource pressure faster, at the cost of more frequent resource checks.
