heartbeat-timeout (MX Series Virtual Chassis)
Syntax
heartbeat-timeout seconds;
Hierarchy Level
[edit virtual-chassis]
Description
Configure the maximum time period within which a Virtual Chassis member router must respond to a heartbeat packet sent by the other member router. When an adjacency disruption or split is detected in the Virtual Chassis configuration, each member router sends a single heartbeat packet to the other member router to determine whether that router is still operating and able to respond. If the other member router responds to the heartbeat packet within the configured or default timeout period, the heartbeat connection helps prevent the member routers from changing primary role roles, which can cause undesirable results.
Both member routers forming the heartbeat connection must
be assigned the routing-engine role in the preprovisioned
Virtual Chassis configuration. The routing-engine role
makes the router eligible to function as either the primary router
or backup router of the Virtual Chassis.
Options
seconds—Number
of seconds within which a Virtual Chassis member router must respond
to a heartbeat packet.
Range: 1 through 60 seconds
Default: 2 seconds
