itrLinkConnectionStatus
Module: MODULES-MIB
OID (symbolic): MODULES-MIB::itrLinkConnectionStatus
OID (numeric): 1.3.6.1.4.1.81.21.3.2.1.14
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This attribute represents the end-to-end connection status of the WAN link. When the connection is ok, the link is 'on(1)'. When the connection is lost the link is 'trying(3)'constantly to re-establish the connection until it becomes 'on(1)' or 'off(2)' .
What is itrLinkConnectionStatus?
Reports the end-to-end logical connection state of this WAN link, separate from the lower-layer itrLinkFunctionalStatus: on(1) means the far-end connection is fully established, off(2) means it's down, and trying(3) means the link is actively and continuously attempting to re-establish the connection; an admin seeing trying(3) persist knows the link keeps failing to complete its handshake rather than being cleanly down.
