LACP Configuration with Cumulux VX Virtual Appliances

In this post LACP will be configured on Cumulus VX virtual appliance. Test simulated on GNS3 Network simulation.

Sample Topology

This is the sample network topology to test LACP.

Configuration on Both Virtual Appliances for LACP

In this configuration, swp1 and swp2 ports used as a slave ports of LAGG0 on both switches.

cumulus@cumulus:~$ net add bond LAGG0 bond slaves swp1,2
cumulus@cumulus:~$ net add bond LAGG0 bond mode 802.3ad
cumulus@cumulus:~$ net add bond LAGG0 bond lacp-rate slow
cumulus@cumulus:~$ net add bond LAGG0 bond miimon 100

Configuration on Both Virtual Appliances for VLAN configuration

In below configuration, VLAN 10 added to bridge(on cumulus vlan-aware bridge) and swp3 configured as an access port with VLAN id 10.

cumulus@cumulus:~$ net add bridge bridge vlan-protocol 802.1ad
cumulus@cumulus:~$ net add bridge bridge ports LAGG0
cumulus@cumulus:~$ net add bridge bridge ports swp3
cumulus@cumulus:~$ net add bridge bridge vids 10
cumulus@cumulus:~$ net add interface swp3 bridge access 10

Experiment

It is also tested that after one of the link has been cut, host still able to ping to other end without any package drop.
