Hi,
Using the display current-configuration command, you can view the configuration commands that take effect in the system. After a group of configurations are complete, you can run this command to check whether the configurations are correct.
display current-configuration [simple] [section string] [| count] [| {begin | include | exclude} TEXT]
display current-configuration {port frameid/slotid/portid | service-port index | ont frameid/slotid/portid ontid | section [configuration-type | configuration-instance]}
About your question, because I can't see the full command, you can refer to:
Add upstream port 0/19/0 to VLAN 10.
huawei(config)#port vlan 10 0/19 0
Thanks!
