reboot
Syntax reboot [active | standby | upgrade] [now]
Context admin
Description
This command reboots the router including redundant
CPMs and all IOMs or upgrades the boot ROMs.
If no options are specified, the user is prompted to confirm the reboot operation. For example:
ALA-1>admin# reboot
Are you sure you want to reboot (y/n)?
If the now option is specified, boot confirmation messages appear.
Parameters active — Keyword to reboot the active
CPM.
Default active
standby — Keyword to reboot the standby
CPM.
Default active
upgrade — Forces card firmware to be upgraded during chassis reboot. Normally, the 7450 ESS OS
automatically performs firmware upgrades on
CPMsand IOM cards without the need for the "upgrade"
keyword. The automatic upgrade must be enabled in the 7450 ESS OS
7 Command Line Interface (CLI)
when rebooting the system.
When the upgrade keyword is specified, a chassis flag is set for the BOOT Loader (boot.ldr) and on the
subsequent boot of the 7450 ESS OS on the chassis, firmware images on
CPMs or IOMs will be
upgraded automatically.
Any
CPMs that are installed in the chassis will be upgraded automatically. For example, if a card is
inserted with down revision firmware as a result of a card hot swap with the latest OS version running,
the firmware on the card will be automatically upgraded before the card is brought online.
If the card firmware is upgraded automatically, a chassis cardUpgraded (event 2032) log event is
generated. The corresponding SNMP trap for this log event is tmnxEqCardFirmwareUpgraded.
During any firmware upgrade, automatic or manual, it is imperative that during the upgrade procedure:
• Power must NOT be switched off or interrupted.
• The system must NOT be reset.
• No cards are inserted or removed.
Any of the above conditions may render cards inoperable requiring a return of the card for resolution.
The time required to upgrade the firmware on the cards in the chassis depends on the number of cards to
be upgraded. The progress of a firmware upgrade can be monitored at the console.
now — Forces a reboot of the router immediately without an interactive confirmation.
