Treatment of Newly Inserted Line Cards

After you insert a line card into the router, the software identifies the card and executes one of three
actions, depending on the contents of the running configuration file:
•
•
•
To find out the type of card that a slot is configured to use, enter the show running-config command.
Most show commands support the pipe character and begin argument. For example, you can use the
Tip
command show running-config | begin card to start the display of the running configuration file at the
point where it lists the cards that are configured on your Cisco 10000 series router.

If the card is not described in the running configuration file, the system enters a basic configuration
into the running configuration file. For example, if you insert a Gigabit Ethernet line card into slot
4, the system adds the following lines to the running configuration:
card 4/0 1gigethernet-1
.
.
.
interface GigabitEthernet4/0/0
no ip address
no ip directed-broadcast
no cdp enable
If the card and slot are described in the running configuration file, the system applies that
configuration to the card.
If the card is of a type different from the one listed in the running configuration file, the software
replaces the configuration with a basic configuration for the newly inserted card.
