Syntax


            
               show system switchover

Syntax (TX Matrix Router)


            
               show system switchover 
               <all-chassis | all-lcc | lcc number | scc>

Syntax (TX Matrix Plus Router)


            
               show system switchover 
               <all-chassis | all-lcc | lcc number | sfc number>

Release Information

Command introduced before JUNOS Release 7.4.

sfc option introduced for the TX Matrix Plus router in JUNOS Release 9.6.

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 master Routing Engine, because the kernel-replication process daemon does not run on the master Routing Engine. This daemon runs only on the backup Routing Engine.

Beginning with JUNOS Release 9.6, if you issue the show system switchover command on the master Routing Engine, the CLI displays a message, error: the kernel-replication subsystem is not running.

Options

all-chassis — (TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, display graceful Routing Engine switchover information for all Routing Engines on the TX Matrix router and the T640 routers configured in the routing matrix. On a TX Matrix Plus router, display graceful Routing Engine switchover information for all Routing Engines on the TX Matrix Plus router and the T1600 routers configured in the routing matrix.

all-lcc — (TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, display graceful Routing Engine switchover information for all T640 routers (or line-card chassis) connected to the TX Matrix router. On a TX Matrix Plus router, display graceful Routing Engine switchover information for all T1600 routers (or line-card chassis) connected to the TX Matrix Plus router.

lcc number — (TX Matrix and TX Matrix Plus router only) (Optional) On a TX Matrix router, display graceful Routing Engine switchover information for a specific T640 router (or line-card chassis) connected to the TX Matrix router. On a TX Matrix Plus router, display graceful Routing Engine switchover information for a specific T1600 router (or line-card chassis) connected to the TX Matrix Plus router.Replace number with 0.

scc — (TX Matrix router only) (Optional) Display graceful Routing Engine switchover information for the TX Matrix router (or switch-card chassis).

sfc — (TX Matrix Plus router only) (Optional) Display graceful Routing Engine switchover information for the TX Matrix Plus router (or switch-fabric chassis).

Additional Information

If you issue the show system switchover command on a TX Matrix backup Routing Engine, the command is broadcast to all the T640 backup Routing Engines that are connected to it.

Likewise, if you issue the show system switchover command on a TX Matrix Plus backup Routing Engine, the command is broadcast to all the T1600 backup Routing Engines that are connected to it.

Output Fields

Table 136 describes the output fields for the show system switchover command. Output fields are listed in the approximate order in which they appear.

Table 136: 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. 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 /var/log/ksyncd for possible causes, or notify Juniper Networks customer support.
Peer state	Routing Engine peer state: Steady State—Peer completed switchover transition. Peer Connected—Peer in switchover transition.
