Replacing A Line Card With The Same Media Type And Port Count - Cisco ASR 9000 Series User Configuration Manual

Managing the Router Hardware
In this example, the line card in slot 3 is removed, and the interface configuration for all four interfaces changes
to "interface preconfigure." However, the "router ospf" reference to a slot 3 interface does not change. If you
replace a line card with another line card that uses the same media type and port count, the configuration
becomes active on the replacement card.
To remove the configuration for a slot after a card is removed, use the no interface preconfigure command
to remove all interface configuration statements for that card in the running configuration. In addition, search
the configuration for any references to the removed interfaces, such as the "router ospf" reference to slot 3 in
the preceding example.
To remove the configuration for a slot when a card is installed, use the no interface command to remove
all interface configuration statements for that card in the running configuration. In addition, search the
configuration for any references to the removed interfaces.
Each line card supports a specific media type (Packet over SONET/SDH [POS] or Ethernet, for example) and
port count. If you replace a line card with one that supports a different media type or port count, you should
review the configuration and revise it to support the replacement line card.

Replacing a Line Card with the Same Media Type and Port Count

When you replace a line card or PLIM with a card that is of the same media type and has the same port count
as the replaced card, the guidelines in the
card is of the same media type and port count, no special procedures are required for card removal and
replacement.
Replacing a Line Card with the Same Media Type and a Different Port Count
When you replace a line card with a card that is of the same media type with a different port count, the
guidelines in
If the new card has a greater port count than the replaced card, the configuration applies to the corresponding
lower port numbers, and the ports that did not exist on the replaced card have no configuration and come up
in the shutdown state.
If the new card supports fewer ports, the existing configuration for the corresponding number of ports on the
new card set is applied. The previous configuration for the removed ports remains in interface preconfigure
state, as shown in the following example:
RP/0/RSP0/CPU0:router# show running-config
