Exos-VM port-sharing causes link-flap and no working lacp

Hello!

I am facing issues when configuring a shared port in exos-vm.

I downloaded from here: https://github.com/extremenetworks/Virtual_EXOS

Version: EXOS-VM_v32.1.1.6.qcow2

I use GNS3 VM and web-client to access the GNS3 server area.

This is a simple setup:

* EXOS-VM.2 # show sharing Load Sharing Monitor Config Current Agg Min Ld Share Ld Share Agg Link Link Up Master Master Control Active Algorithm Flags Group Mbr State Transitions ================================================================================ 1 LACP 1 A 1 - R 3 2 - R 2 ================================================================================ Link State: A-Active, D-Disabled, R-Ready, NP-Port not present, L-Loopback Minimum Active: (<) Group is down. # active links less than configured minimum Load Sharing Algorithm: (L2) Layer 2 address based (L3_L4) Layer 3 address and Layer 4 port based Flags: A - All: Distribute to all members, d - Dynamically created shared port, L - Local Slot: Distribute to members local to ingress slot, P - Port Lists: Distribute to per-slot configurable subset of members, R - Resilient Hashing enabled. Number of load sharing trunks: 1

* EXOS-VM.3 # show sharing Load Sharing Monitor Config Current Agg Min Ld Share Ld Share Agg Link Link Up Master Master Control Active Algorithm Flags Group Mbr State Transitions ================================================================================ 1 LACP 1 A 1 - R 44 2 - A 51 ================================================================================ Link State: A-Active, D-Disabled, R-Ready, NP-Port not present, L-Loopback Minimum Active: (<) Group is down. # active links less than configured minimum Load Sharing Algorithm: (L2) Layer 2 address based (L3_L4) Layer 3 address and Layer 4 port based Flags: A - All: Distribute to all members, d - Dynamically created shared port, L - Local Slot: Distribute to members local to ingress slot, P - Port Lists: Distribute to per-slot configurable subset of members, R - Resilient Hashing enabled. Number of load sharing trunks: 1

Log indicates link flapping

Is there limitations in Exos-VM for GNS3 regarding sharing? Maybe another release is working?

I dont know if lacp works with GNS3, I would use static links. But then, that would not solve the link flapping. Maybe something with the host running gns3 is running out of resources or too much CPU ?

Thank you for reply.

I have update on this, it seems to be issues when using GNS3-VM and Web-mode on top of VMware.

I have installed GNS3 locally on pc with windows 10 using hyper-v and it works.
