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 packet processing card migration. These

migration can be invoked. Follow the instructions below to manually initiate a packet processing card migration. These
instructions assume you are at the root prompt for the Exec mode.
Step 1
Initiate a manual packet processing card migration by entering the following command:
[local]host_name# card migrate from original_slot# to final_slot#
You will receive the following prompt:
Are You Sure? [Yes|No]:
For a complete description of the above command, see the Exec Mode Commands chapter of the Command line
Interface Reference.

Step 2
Press
Y
to start the migration.
Step 3
Verify that the migration was successful by entering the following command.
[local]host_name#show card table
Check the entry in the Oper State column next to the packet processing card that was just migrated from. Its state should
be Standby. The state of the packet processing card migrated to should be Active.

Manually Initiating a Line Card or SPIO Switchover
Ethernet line cards are installed in the half-height slots at the rear of the chassis. This design allows for two half-height
line cards to be installed behind every application card (vertical redundancy). With two line cards installed, booting their
associated application card causes the card in the upper-rear chassis slot to automatically be made active while the card
in the lower-rear chassis slot will automatically be placed in standby mode. In the event that the active card experiences
a failure, the system will automatically switch traffic to the standby card in the lower slot.

The XGLC is a full-height card that supports 1:1 side-by-side redundancy. Side-by-side (horizontal) redundancy allows
two XGLC cards installed in neighboring slots to act as a redundant pair. Side-by-side pair slots for the XGLC are: 17-
18, 19-20, 21-22, 23-26, 27-28, 29-30, and 31-32. If the XGLCs are not configured for side-by-side redundancy, they
run independently without redundancy.

When configured for side-by-side redundancy, The XGLC is referenced only by the upper slot number (17 through 23,
26 through 33); the lower slot number is not recognized. All other configuration commands work as if the side-by-side
slots were top-bottom slots. Configuration commands directed at the bottom slots either fail with errors or are
disallowed.
