|How to configure Virtual Chassis in Juniper EX-2300 Switch
This article will provide to configure the Virtual Chassis in EX-2300 Juniper
Virtual Chassis is a feature in Ethernet Switches that allows you to interconnect two or more switches, enabling them to operate as a unified, single, high-bandwidth switch.
It provides network resiliency in the form of redundant Routing Engines and network expansion flexibility with minimal impact to a configuration.
EX 2300 Virtual Chassis Configuration
All EX-2300 switch models support Virtual Chassis, and you can interconnect different models, which allows you to choose among a range of possible port configurations within the same Virtual Chassis.
The Virtual Chassis configuration includes a master switch and a backup switch, with all other switches in the configuration designated as linecard member switches.
The procedure to configuration steps applicable to a Virtual Chassis are:-
- Power on only the switch that you will use as the master switch.
- EX2300 switches do not have any ports that are configured by default as VCPs but you can configure the 10-Gbps Ethernet uplink ports as VCPs, and use those to interconnect the switches into a Virtual Chassis
- Set the master switch into mixed mode, and reboot the switch to complete the configuration:
user@device> request virtual-chassis mode mixed reboot
- On each individual member switch, configure the SFP+ uplink ports that will be used as VCPs to interconnect the member switches .
user@device> request virtual-chassis vc-port set pic-slot 1 port 2
user@device> request virtual-chassis vc-port set pic-slot 1 port 3
- To Check the VC-Port Status
user@device> show virtual-chassis vc-port
Interface Type Trunk Status Speed Neighbor

PIC / Port
1/2 Configured -1 Down 10000
1/3 Configured -1 Down 10000
- Cable the ports interconnecting the members if they were not connected earlier.
- Specify the preprovisioned configuration mode:
user@device# set virtual-chassis preprovisioned
- (Optional: Recommended for a two-member Virtual Chassis) Disable the split and merge feature:
user@device# set virtual-chassis no-split-detection
- Specify all the members that you want included in the Virtual Chassis, listing each switch’s serial number with the desired member ID and role
user@device# set virtual-chassis member 0 serial-number abc123 role routing-engine
user@device# set virtual-chassis member 1 serial-number def456 role routing-engine
user@device# set virtual-chassis member 2 serial-number ghi789 role line-card
user@device# set virtual-chassis member 3 serial-number jkl012 role line-card
- Commit/Save the configured items.
- Power on the other member witches. The member IDs and roles have been determined by the configuration, so you can power on the member switches in any order.
- To check the Virtual Chassis Status
user@device> show virtual-chassis status
