I Start using GNS3 (Version 22.1.1.5) and trying to set up a link aggregation.

When using the standard sharing command I'm getting the following error:

* EXOS-VM.3 # enable sharing 1 grouping 1-2 algorithm address-based lacp
Error: PC environment supports only round robin algorithm.

but Round Robin is not an option when doing the configuration:

* EXOS-VM.4 # enable sharing 1 grouping 1-2 algorithm ?
  address-based   address based
* EXOS-VM.4 # enable sharing 1 grouping 1-2 algorithm

Found out the rigth command for it and tried to configure:
* EXOS-VM.1 # enable sharing 1 grouping 1-2 algorithm roundRobin-based lacp
                                                      ^
%% Invalid input detected at '^' marker.
anyone an idear how to fix that?


Thanks

There are lots of limitaion on virtual EXOS switches and I remember LAG is one if them.
Actually round robin is NOT a kind of algorithm for real switches.
Just try "enable sharing 1 group 1-2" and it will work.

You still can add lacp on EXOS VM: "enable sharing 1 grouping 1,2 lacp"

The following example defines a static load-sharing group that contains ports 9 through 12, and uses the first port in the group as the master logical port 9:

enable sharing 9 grouping 9-12 

In this example, logical port 9 represents physical ports 9 through 12.
When using load sharing, you should always reference the master logical port of the load-sharing group.

Coming to the algorithm used in LACP for extreme switches we may use either standard or custom algorithm. For more information you may refer to page 219 of EXOS user guide 21.1 PDF.
