atmVnnT309
Module: ACMIB
OID (symbolic): ACMIB::atmVnnT309
OID (numeric): 1.3.6.1.4.1.1751.2.18.5.17.1.13
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: Timer T309 value - seconds
What is atmVnnT309?
This OID stores the T309 timer value in seconds, which is the keep-alive or status enquiry timeout used to detect if the ATM signaling link to the network is still alive. Network engineers set this timer to detect dead links and trigger failover in case the network becomes unreachable, maintaining the stability of virtual circuits. With T309 set to 30 seconds, the system sends keep-alive messages every 30 seconds and disconnects if no response is received, indicating the network link is down.
