Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Candidate configuration

When you use OS10 configuration commands in Transaction-based configuration mode, changes do not take effect immediately and are stored in the candidate configuration. The configuration changes become active only after you commit the changes using the commit command. Changes in the candidate configuration are validated and applied to the running configuration.

The candidate configuration allows you to avoid introducing errors during an OS10 configuration session. You can make changes and then check them before committing them to the active, running configuration on the switch.

To check differences between the running configuration and the candidate configuration, use the show diff candidate-configuration running-configuration command.

For example, before entering Transaction mode, you can check that no new configuration commands are entered. If the show command does not return output, the candidate-configuration and running-configuration files are the same. Then start Transaction mode, configure new settings, and view the differences between the candidate and running configurations. Decide if you want to commit the changes to the running configuration. To delete uncommitted changes, use the discard command.

OS10# show diff candidate-configuration running-configuration
OS10#
OS10# start transaction
OS10# configure terminal
OS10(config)# interface vlan 100
OS10(conf-if-vl-100)# exit
OS10(config)# interface ethernet 1/1/15
OS10(conf-if-eth1/1/15)# switchport mode trunk
OS10(conf-if-eth1/1/15)# switchport trunk allowed vlan 100
OS10(conf-if-eth1/1/15)# end

OS10# show diff candidate-configuration running-configuration

Commit configuration changes in candidate configuration in Transaction mode

1. Change to Transaction-based configuration mode from EXEC mode.

   start transaction

2. Enter configuration commands. For example, enable an interface from INTERFACE mode.

   interface ethernet 1/1/1
   no shutdown

3. Save the configuration changes to the running configuration.

   do commit

   After you enter the commit command, the current OS10 session switches back to the default behavior of committing all configuration changes automatically.

OS10# start transaction
OS10# configure terminal
OS10(config)#
OS10(config)# interface ethernet 1/1/1
OS10(config-if-eth1/1/1)# no shutdown
OS10(config-if-eth1/1/1)# do commit

Compressed configuration views

To display only interface-related configurations in the candidate configuration, use the show candidate-configuration compressed and show running-configuration compressed commands. These views display only the configuration commands for VLAN and physical interfaces.
