= Cluster network card replacement
|
|
|
|
When you replace a network card, the MAC address changes.
|
|
The MAC address can be part of the DHCP or SR-IOV Operator configuration, router configuration, firewall rules, or cloud-native application configuration.
|
|
Before you bring back a node online after replacing a network card, you must verify that these configurations are up-to-date.
|
|
|
|
[IMPORTANT]
|
|
====
|
|
If you do not have specific procedures for MAC address changes within the network, contact your network administrator or network hardware vendor.
