How to configure LACP on Juniper Switch EX3300-24P with Synology NAS
- On the physical Synology NAS make sure both LAN ports are connected to your switch, in my case these are ports 18/19 on the Juniper switch.
- SSH into your Juniper Switch
- Check if you have any AE (Aggregated Ethernet) interfaces available.
- run show config
- look for interfaces that start with “ae“
- In this example I am going to be using interface ae1
- Enter into “edit” mode
- If you do not see any ae interfaces, then run the following (this will create 2)
set chassis aggregated-devices ethernet device-count 2- The commands below will setup LACP/LAG on ports 18 and 19 and bond them to logical interface ae1 and sets the link speed to 1GB. I also set the periodic to slow as this is the default value in Cisco, but this may not be necessary.
set interfaces ae1 aggregated-ether-options lacp active
set interfaces ae1 unit 0 family ethernet-switching port-mode trunk
set interfaces ae1 unit 0 family ethernet-switching vlan members vlan10
set interfaces ae1 unit 0 family ethernet-switching vlan native-vlan-id default
set interfaces ae1 aggregated-ether-options link-speed 1g
set interfaces ae1 aggregated-ether-options lacp periodic slow
set interfaces ge-0/0/18 ether-options 802.3ad ae1
set interfaces ge-0/0/19 ether-options 802.3ad ae1
commit- Open up the Synology DSM Manager
- (WARNING: You must setup the Switch side first)
- Go to Control Panel > Network > Network Interface. Click Create > Create Bond.
- Select “IEEE 802.3ad Dynamic Link Aggregation” click next.
- Select both interfaces click next.
- On the Network Setup screen, I set your network configuration settings. In my case I left DHCP since I use network reservations in my environment.
- Click on Apply.
- Click “Save“
- If you did everything correctly you should see Network Status of 2000Mbps under the Bond connection.
