how to check the default configuration of switch’s interface

When taking into consideration that default settings are invisible in a configuration file, it is a good information that Huawei’s S3700/S5700 switches have such possibility to display default settings for ethernet interfaces. The ‘display this include-default’ command displays the effective configurations in the current view, including the unchanged default configurations.

how to configure multiple interfaces at the same time

This is an useful feature, specially if we want to configure Huawei’s switch, where there are lots of physical interfaces. Very often, some of interfaces have the same configuration. Instead of configure the interfaces one by one it is easier to configure multiple interfaces at the same time. It improves the efficiency.

Let’s assume that you want to add 5 GE interfaces to VLAN 100:

[labnario]port-group labnario
[labnario-port-group-labnario]group-member GigabitEthernet 0/0/1 to GigabitEthernet 0/0/5
[labnario-port-group-labnario]port link-type access
[labnario-port-group-labnario]port default vlan 100

[labnario]dis cur | beg port-group
port-group labnario
 group-member GigabitEthernet0/0/1
 group-member GigabitEthernet0/0/2
 group-member GigabitEthernet0/0/3
 group-member GigabitEthernet0/0/4
 group-member GigabitEthernet0/0/5
