Replace a line card
If you are replacing a line card with a line card of the same type, you may replace the card without any
additional configuration.
If you are replacing a line card with a line card of a different type, remove the card and then remove the
existing line card configuration using the command
no linecard. If you do not, FTOS reports a card
mismatch (Message 6) when you insert the new card, and the installed line card has a card mismatch status.
To clear this line card mismatch status and bring the line card online, specify the type of line card you
inserted using the command
linecard, as shown in Figure 18-7.

Hitless Behavior
Hitless Behavior is supported only on platform: c e
Hitless behavior is supported on E-Series ExaScale e
x
with FTOS 8.2.1.0. and later.
Hitless is a protocol-based system behavior that makes an RPM failover on the local system transparent to
remote systems. The system synchronizes protocol information on the standby and primary RPMs such
that, the event of an RPM failover, there is no need to notify remote systems of a local state change.
