Manually Initiating a Packet Processing Card Migration
When the system boots up, all installed PSCs enter the ―standby‖ mode. The standby mode indicates that the card is
available for use but is not configured for operation. Installed components can be made active through the software
configuration process. Cards that are not configured to enter the ―active‖ mode will remain in standby mode for use as
redundant components.
available for use but is not configured for operation. Installed components can be made active through the software
configuration process. Cards that are not configured to enter the ―active‖ mode will remain in standby mode for use as
redundant components.
In the event of PSC critical failure, tasks will be automatically be migrated from the active card to a redundant card in
standby mode. The line card installed behind the PSC that was formerly active will still be used to maintain the
interfaces to external network equipment. Installed Redundancy Crossbar Cards (RCCs) will provide a path for
signalling and data traffic between the line card and the now active PSC. Therefore, redundant PSCs do not require that
line cards be installed behind them.

In the event that an issue arises that is not severe enough for the system to perform an automatic migration, a manual
migration can be invoked. Follow the instructions below to manually initiate a PSC migration. These instructions

migration can be invoked. Follow the instructions below to manually initiate a PSC migration. These instructions
assume you are at the root prompt for the Exec mode:
Step 1
Initiate a manual PSC migration by entering one of the following commands:
For PSC:
Keyword/Variable
Description
from
Specifies the chassis slot number of the PSC that is being migrated from. original_slot can be any value
between 1 through 7, and 10 through 16.
between 1 through 7, and 10 through 16.
to
Specifies the chassis slot number of the PSC that is being migrated to. Variable final_slot can be any value
between 1 through 7, and 10 through 16.
between 1 through 7, and 10 through 16.
You will receive the following prompt:
Step 2
Press to start the migration.
Step 3
Verify that the migration was successful by entering the following command at the prompt:
Check the entry in the Oper State column next to the PSC that was just migrated from. Its state should be Standby. The
state of the PSC migrated to should be Active.
state of the PSC migrated to should be Active.
