How to configure interface groups on AR routers


If users need to perform the same configuration on multiple Ethernet interfaces, they can add the Ethernet interfaces into an interface group. Users only need to run the configuration command of a function once in an inteface group view to configure the function for all Ethernet interfaces included in the interface group. In this way, interfaces can be configured in batches and repeated configurations are reduced.
Interfaces can be added into two types of interface groups: permanent interface groups and temporary interface groups, which have the same function. However, a temporary group is automatically deleted by the system after you quit the view of the temporary interface group.
Configure a permanent interface group as follows:
[Huawei] port-group portgroup1
[Huawei-port-group-portgroup1] group-member ethernet2/0/0 to ethernet2/0/1 //Add interface Eth2/0/0 and interface Eth2/0/1 to the interface group portgroup1.
Configure a temporary interface group as follows:
[Huawei] port-group group-member ethernet2/0/0 to ethernet2/0/1 //Add interface Eth2/0/0 and interface Eth2/0/1 to a temporary interface group.
AR550 series products do not support interface groups.

How to configure the MP-Group of E1 interfaces of AR routers

MP indicates the Multi-Link Point-to-Point Protocol (MLPPP), in which multiple PPP links are bound together. MP binding is often performed in scenarios where a 2 Mbit/s E1 dedicated line cannot meet the service requirements.
MP interfaces transmit data by packets. AR routers only support the binding of interfaces of the same card.

[Huawei] interface mp-group 0/0/1 //Create an MP-Group interface and enter the view of the interface.
[Huawei-Mp-group0/0/1] undo discriminator //(Optional) Disable the terminal endpoint identifier negotiation function which is enabled by default. You can disable the function when the interface cannot interconnect with the devices of other manufacturers.
[Huawei-Mp-group0/0/1] ip address 24 //You can run the ip address ppp-negotiate command to allow the peer end to allocate the IP address generated through PPP negotiation to the interface.
[Huawei-Mp-group0/0/1] interface serial 2/0/0 //Enter the view of the specified physical interfaces (PPP type)
[Huawei-Serial2/0/0] ppp mp mp-group 0/0/1 //Add the physical interface. You can repeat this step to add multiple interfaces.
[Huawei-Serial2/0/0] restart //Restart the related physical interfaces.

Can the E1 interface of an AR router interconnect with MP-group interfaces
The E1 interface of an AR router cannot interconnect with MP-group interfaces. The network works properly only when the configurations of the interfaces on both interconnected ends are consistent.

Link group configuration scenario of an AR router
The link-group command is used to create a link group in the SPR and access the link group view. In actual application, link requirements vary with services. To facilitate link deployment and reuse, add the links into a group, and apply services to the link group to implement link selection. The use of the link group needs to be supported by the smart policy routing parameters, and ACLs that differentiate service flows. For details about the configuration, see the URL: Example for Configuring SPR.

Can physical interfaces be configured as monitored interfaces of a VRRP group on the AR router
Physical interfaces can be configured as monitored interfaces of a VRRP group on the AR router.

How many security policy groups can an interface of an AR router apply
One interface of an AR router can apply only one security policy group, and vice versa (except for the multilink shared security policy group). To apply another security policy group on the interface, cancel the previous policy from the interface first.
