How to configure LACP on VMware to Juniper

23 Oct

I have few VMware machines using dual or quad uplink connected to my Juniper switch, and how to configure link-aggregation between VMWare and Juniper switch? I will use lacp on VMware and Juniper switch, here we go:

  1. Make sure that your VMware machine is connected to your switch with minimum 2 ports and select those ports. See picture below:
  2. Then configure the management interface, I’m using vlan 10 (tagged) for VMware management port. See picture below:
  3. Then configure the IP address for VMware management, see below:

We already setup the VMware host and ready to configure the switch, I’m using Juniper EX4200.

  1. Login to your switch
  2. Enter to configuration mode
  3. Here is the complete setup on my switch:

set chassis aggregated-devices ethernet device-count 5
set interfaces ae1 description “lacp for vmware 3”
set interfaces ae1 aggregated-ether-options lacp active
set interfaces ae1 aggregated-ether-options lacp periodic slow
set interfaces ae1 unit 0 family ethernet-switching port-mode trunk
set interfaces ae1 unit 0 family ethernet-switching vlan members 10
set interfaces ge-0/0/8 ether-options 802.3ad ae1 lacp force-up
set interfaces ge-0/0/9 ether-options 802.3ad ae1 lacp force-up
commit

The see the lacp status:

And done! My VMware machine have 2Gbps uplink 🙂
