Information About Switch Profiles

Information About Switch Profiles
Several applications require consistent configuration across Cisco Nexus Series switches in the network. For
example, with a Virtual Port Channel (vPC), you must have identical configurations. Mismatched configurations
can cause errors or misconfigurations that can result in service disruptions.
The configuration synchronization (config-sync) feature allows you to configure one switch profile and have
the configuration be automatically synchronized to the peer switch. A switch profile provides the following
benefits:
• Allows configurations to be synchronized between switches.
• Merges configurations when connectivity is established between two switches.
• Provides control of exactly which configuration gets synchronized.
• Ensures configuration consistency across peers through merge and mutual-exclusion checks.
• Provides verify and commit semantics.
• Supports configuring and synchronizing port profile configurations.
• Provides an import command to migrate existing vPC configurations to a switch profile.
Switch Profile Configuration Modes
The switch profile feature includes the following configuration modes:
• Configuration Synchronization Mode
• Switch Profile Mode
• Switch Profile Import Mode
Configuration Synchronization Mode
The configuration synchronization mode (config-sync) allows you to create switch profiles using the config
sync command on the local switch that you want to use as the master. After you create the profile, you can
enter the config sync command on the peer switch that you want to synchronize.
Switch Profile Mode
The switch profile mode allows you to add supported configuration commands to a switch profile that is later
synchronized with a peer switch. Commands that you enter in the switch profile mode are buffered until you
enter the commit command.
Switch Profile Import Mode
When you upgrade from an earlier release, you have the option to enter the import command to copy supported
running-configuration commands to a switch profile. After entering the import command, the switch profile
mode (config-sync-sp) changes to the switch profile import mode (config-sync-sp-import). The switch profile
import mode allows you to import existing switch configurations from the running configuration and specify
which commands you want to include in the switch profile.
