Licensing Requirements and Limitations for Link Aggregation

Licensing Requirements and Limitations for Link Aggregation

This section describes the notes about configuring an Eth-Trunk.

Involved Network Elements

None

Licensing Requirements

Ethernet link aggregation is a basic feature of a router and is not under license control.

Feature Limitations

When deploying Link Aggregation on the router, pay attention to the following:

  • AR100-S, AR110-S, AR120-S, AR150-S2, and AR160-S series do not support link aggregation.

Before an Eth-Trunk Is Configured:
  • Member interfaces cannot be configured with some services. For example, the link type of a member interface cannot be modified, and static MAC address entries cannot be configured.

  • An Eth-Trunk cannot be added to another Eth-Trunk.
  • Member interfaces of an Eth-Trunk must use the same Ethernet type and rate.

    Interfaces that use different Ethernet types and rates cannot join the same Eth-Trunk. For example, GE and FE interfaces cannot join the same Eth-Trunk, and GE electrical and optical interfaces cannot join the same Eth-Trunk.

  • If an interface of the local device is added to an Eth-Trunk, an interface of the remote device directly connected to the interface of the local device must also be added to an Eth-Trunk so that the two ends can communicate.
  • Both devices of an Eth-Trunk must use the same link aggregation mode.
After an Eth-Trunk Is Configured:
  • An Ethernet interface can be added to only one Eth-Trunk. To add an Ethernet interface to another Eth-Trunk, delete it from the original one first.
  • After interfaces are added to an Eth-Trunk, the Eth-Trunk learns MAC addresses and ARP entries but member interfaces do not.
  • Before deleting an Eth-Trunk, delete member interfaces from the Eth-Trunk.
