tnSysLinkPassThro
Module: TN-MGMT-MIB
OID (symbolic): TN-MGMT-MIB::tnSysLinkPassThro
OID (numeric): 1.3.6.1.4.1.868.2.5.3.1.1.2.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Devices which support this feature allow write for enabling or disabling the feature. Most 2-port devices support this feature. Link pass through when enabled monitors the link status of one port, any change in its operational state is passed on to the other port and vice-versa. For eg: If Port 1 becomes operationally down, the Port 2 is brought down. When Port 1 becomes operational again, Port 2 is also brought up.
What is tnSysLinkPassThro?
This read-write setting enables or disables Link Pass Through on a 2-port device: when enabled, if one port goes operationally down, the other port is automatically brought down too (and vice versa when it recovers). It's commonly used so that a fault on one side of a media converter is visible to equipment on the other side rather than being silently absorbed.
