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

[labnario-port-group-labnario]dis cur interface gig
#
interface GigabitEthernet0/0/1
 port link-type access
 port default vlan 100
#
interface GigabitEthernet0/0/2
 port link-type access
 port default vlan 100
#
interface GigabitEthernet0/0/3
 port link-type access
 port default vlan 100
#
interface GigabitEthernet0/0/4
 port link-type access
 port default vlan 100
#
interface GigabitEthernet0/0/5
 port link-type access
 port default vlan 100
...

[labnario]display port-group all
Portgroup: labnario
GigabitEthernet0/0/1
GigabitEthernet0/0/2
GigabitEthernet0/0/3
GigabitEthernet0/0/4
GigabitEthernet0/0/5

Note that only physical interfaces of the same board can be added to an interface group.
