tnEthRingGuardTime
Module: TN-ETH-RING-MIB
OID (symbolic): TN-ETH-RING-MIB::tnEthRingGuardTime
OID (numeric): 1.3.6.1.4.1.7483.6.1.2.72.1.1.1.7
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-create
Description: The value of tnEthRingGuardTime specifies the guard timer, in deciseconds, of a Ring-APS (R-APS) node.
The guard timer is used to prevent the Ethernet Ring node from acting upon outdated R-APS messages and prevent the possibility of forming a closed loop.
While the guard timer is running, any received R-APS Request/State and Status information is blocked and not forwarded to the Priority Logic. When the guard timer is not running, the R-APS Request/State and Status information is forwarded unchanged.
What is tnEthRingGuardTime?
The R-APS guard timer, in deciseconds (1-20, default 5), during which the node blocks incoming Ring-APS Request/State and Status messages from reaching its priority logic; it exists to stop the node from acting on stale R-APS messages and accidentally forming a closed loop.
