show system switchover

Syntax



show system switchover

Syntax (Routing Matrix)



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

Release Information

Command introduced before JUNOS Release 7.4.

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 on the backup Routing Engine. This command is not supported on the master Routing Engine.

Options

all-lcc — (Routing matrix only) (Optional) Display graceful Routing Engine switchover information for all T640 routing nodes (or line-card chassis) connected to a TX Matrix platform.

lcc number — (Routing matrix only) (Optional) Display graceful Routing Engine switchover information for a specific T640 routing node (or line-card chassis) connected to a TX Matrix platform. Replace number with a value from 0 through 3.

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

Additional Information

By default, when you issue the show system switchover command on a TX Matrix master Routing Engine, the command is broadcast to all the T640 master Routing Engines connected to it. Likewise, if you issue the same command on the TX Matrix backup Routing Engine, the command is broadcast to all the T640 backup Routing Engines that are connected to it.

Output Fields

Table 134 describes the output fields for the show system switchover command. Output fields are listed in the approximate order in which they appear.

Table 134: 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.
