Dell EMC SmartFabric OS10 User Guide Release 10.5.0

To enter configuration commands using an OS9 command syntax, use the feature config-os9-style command in CONFIGURATION mode and log out of the session. If you do not log out of the OS10 session, configuration changes made with OS9 command syntaxes do not take effect. After you log in again, you can enter OS9 commands, but only in the new session.

For example, to use OS9 commands to configure VLAN 11 on Ethernet port 1/1/15:

OS10(config)# feature config-os9-style
OS10(config)# interface vlan 11
OS10(conf-if-vl-11)# tagged ethernet 1/1/15 

OS10(conf-if-vl-11)# show configuration
!
interface vlan11
 no shutdown
 tagged ethernet 1/1/15

To disable OS9 configuration-style mode, use the no feature config-os9-style command.
