Turn Multiple Switches into ONE: Configure Virtual Chassis on Juniper

Want to know how to configure two switches to function as one logical device. This video walks you step by step how to configure a virtual chassis on a Juniper EX series switch.

Virtual Chassis Requirements:
1. Same version of code
2. Connect the VC ports
3. Enable split-detection (for two member VC only)

NOTE: the default termination for which switch will become the master is the switch with the longest uptime. You can override the default behavior by manually specifying which switch you want to use by pre-provisioning the virtual chassis config. Check out the Juniper link below for detailed steps on how to perform this process

Short, sweet, and to the point. Thank you!

Great video Jon, thanks for this. I'll be implementing a stack for 2x EX4300-32F switches in one of our locations via the 40Gbit QSFP+ . Once the transceivers are delievered I'll let you know how it works out. I'm slowly being converted to Juniper from Cisco ;)

Hello, great content!

Comparing Juniper VC with Cisco stacking technologies.
I understand that VC would be more like Cisco VSS or stackwise virtual. And not as much as Cisco stackwise which is a backplane stacking and uses proprietary stack cables, and does not use ethernet cables like virtual stackwise or VSS.
As I understarnd Juniper VC uses Ethernet cables (SFP+, QSFP+, DAC cables, etc) to form the VC.

IS this correct?

Thank you!

Hello Jon Green, I have a question as follow: does juniper support virtual chassis on virtualized Juniper QFX device? Can we lab the VCS feature of Switch Juniper on EVE-ng?

[ykorbmf]

need to configure all switches for VLANs configurations if we are creating a virtual chassis ?

[miss_sapphire]

If you have two switches that have different versions, wouldn't setting chassis auto-image-upgrade handle the differences?

I have 2 SRXs running different versions of Junos OS. Can I copy the Junos OS to a tftp server and upgrade the other SRX?

Hi Jon, thank God I found you! Can you do the same with aggregated link? Works as one VC link? Please, answer me :)

Great videos, subscribed OFC.

Can we do the configuration through Mist Cloud ? Any Videos/Guide on it.

When you did run the "show interface terse" command few interface displayed were
ge-0/1/0
ge-0/1/1

ge-1/1/0
ge-1/1/1

Can you explain these?

Great video
I set ex3400-24t to ex3400-24p
connected, but PoE does not work
Can you help me?

what is the benefit by combining these two switches, only management ? again thank you for your work.. you are a best teacher but i will suggest you start giving some more detail info in every clip.

what about if there are 3 or more switches? how do we stack them to master switch? thank you.
