To display the hash calculated for the running configuration:

This hash is only valid for comparison to a baseline hash if

Scenarios that block the configuration restoration process
The configuration restoration process is blocked in the following scenarios:
• If the restored configuration file requires a reboot.
• If the restored configuration changes the entire configuration (for example, module add or remove).

Limitations
Switch configuration restore without reboot feature does not support the following scenarios:
• Removing a physically present member through cfg-restore command
• Flex-module provisioning or removal on standalone or a stack
• Module provisioning or removal on standalone or a stack
• Adding a VLAN when the VLAN limit is already reached by having dynamic VLANs. Due to timing issues, ports
or dynamic VLANs take some time to become offline or be removed, even after applying a removal command.
In such a case, restore commands fail as normal CLI commands.
• The maximum number of backup configuration files has been increased from three to five. When the firmware
is downgraded to lower versions, the show config files command displays the details to only three
configuration files.
• Restore is allowed based on the available system resource factors.
Blocking of configuration from other sessions
All write operations are not allowed from other sessions (CLI/WebUI/SNMP/REST, and so on) during a
configuration restoration process. Only read operation is allowed. Attempts to use write operation results in the
Configuration restore is in progress, configuration changes are temporarily
disabled error. The following show commands are blocked during a configuration restoration process:
