show system switchover

Syntax

Syntax (MX Series Router)

Description

Display whether graceful Routing Engine switchover is configured, the state of the kernel replication (ready or synchronizing), any replication errors, and whether the primary and standby Routing Engines are using compatible versions of the kernel database.

Note:

Issue the show system switchover command only on the backup Routing Engine. This command is not supported on the primary Routing Engine because the kernel-replication process daemon does not run on the primary Routing Engine. This process runs only on the backup Routing Engine.

Options

all-members	(MX Series routers only) (Optional) Display graceful Routing Engine switchover information for all Routing Engines on all members of the Virtual Chassis configuration.
local	(MX Series routers only) (Optional) Display graceful Routing Engines switchover information for all Routing Engines on the local Virtual Chassis member.
member `member-id`	(MX Series routers only) (Optional) Display graceful Routing Engine switchover information for all Routing Engines on the specified member of the Virtual Chassis configuration. Replace `member-id` with a value of 0 or 1.

Additional Information

If you issue the show system switchover command on the active Routing Engine in the primary router of an MX Series Virtual Chassis, the router displays a message that this command is not applicable on this member of the Virtual Chassis.

Output Fields

Table 1 describes the output fields for the show system switchover command. Output fields are listed in the approximate order in which they appear.

Table 1: show system switchover Output Fields
Field Name	Field Description
`Graceful switchover`	Display graceful Routing Engine switchover status: `On`—Indicates `graceful-switchover` is specified for the `routing-options` configuration command. `Off`—Indicates `graceful-switchover` is not specified for the `routing-options` configuration command.
`Configuration database`	State of the configuration database: `Ready`—Configuration database has synchronized. `Synchronizing`—Configuration database is synchronizing. Displayed when there are updates within the last 5 seconds. `Synchronize failed`—Configuration database synchronize process failed.
`Kernel database`	State of the kernel database: `Ready`—Kernel database has synchronized. This message implies that the system is ready for GRES. `Synchronizing`—Kernel database is synchronizing. Displayed when there are updates within the last 5 seconds. `Version incompatible`—The primary and standby Routing Engines are running incompatible kernel database versions. `Replication error`—An error occurred when the state was replicated from the primary Routing Engine. Inspect Steady State for possible causes, or notify Juniper Networks customer support.
`Switchover Status`	Switchover Status: `Ready`—Message for system being switchover ready. `Not Ready`—Message for system not being ready for switchover.
`Platform Components`	Platform Components: FEB1: `Not Online`—The backup FEB2 is not yet online. `Online`—The backup FEB2 is online. FEB1-PFE0, FEB1- PFE1: `Ready`—Message for FEB1- PFE0, or FEB1- PFE1 being switchover ready. The backup PFE is ready for switchover (does not include time for routes or nexthops for a scaled configuration). `Not Online`—The backup PFE is not yet online. `Sync In Progress`—Two-minute synchronization in progress when information flow data-path is programmed on the backup PFE (does not include time for routes or next-hops programming).
