Setup Guide

Replacing a Line Card
To replace a line card with a line card of the same type, you can remove the old card and insert a new card without any additional
conguration.
To replace a line card with a dierent card type, remove the card and then remove the existing line-card conguration for the slot using the
command
no linecard slot-id provision.
Dell(conf)# no linecard 3 provision
If you do not remove the existing line-card conguration, the status of the newly installed line card displays as mismatch card type.
Dell# show linecard 5
-- Linecard 5 --
Status : type mismatch - mismatch card type

Hitless Behavior
Hitless is a protocol-based system behavior in a dual-RPM chassis that is transparent to remote systems. In the event of a control-plane
failover, it is not necessary to notify the remote systems of a local state change.
Hitless protocols are compatible with other hitless and graceful restart protocols. A software or hardware exception may trigger hitless
failovers, or a forced failover using the command line interface (CLI).
For example, if you congure hitless open shortest path rst (OSPF) over hitless the link aggregation control protocol (LACP) link
aggregation groups (LAGs), both features work seamlessly to deliver a hitless OSPF-LACP result. However, to achieve a hitless result, if
the hitless behavior involves multiple protocols, all protocols must be hitless. For example, if OSPF is hitless but bidirectional forwarding
detection (BFD) is not, OSPF operates in hitless mode and BFD aps upon a control-plane failover.
The following protocols are hitless:
• 802.1X (802.1X)
• Bidirectional Forwarding Detection (Bidirectional Forwarding Detection (BFD))
• Internet Group Management Protocol (Internet Group Management Protocol (IGMP) and IGMP Snooping)
