Uplink ports 2 and 3

Any of the 4 uplink ports (ports 0 through 3)

EX3400

None

All QSFP+ uplink ports (PIC slot 1, ports 0 and 1)

Any SFP+ uplink ports

Note:  You cannot use ports with SFP transceivers as VCPs on EX3400 switches to form a Virtual Chassis.

4 25-Gbps SFP28 ports on the front panel

None

EX4100-F

4 10-Gbps SFP+ ports on the front panel

4 10-Gbps SFP+ ports on the front panel

None

EX4200

2 ports on the rear panel

None

Any uplink module ports (SFP, SFP+, or XFP) or through an SFP+ port on the EX4200-24F switch

Note: You cannot set a 1000BASE-T copper SFP transceiver (EX-SFP-1GE-T) connection as a VCP on EX4200 switches.

EX4300

None

All QSFP+ ports

Any uplink ports installed with SFP+ or QSPF+ transceivers

Note: On 32-port EX4300 switches, you can’t use the four built-in 10-Gigabit Ethernet SFP+ ports as VCPs.

EX4300 multigigabit models (EX4300-48MP)

4 40-Gbps QSFP+ ports on the rear panel

None

None

EX4400 (Including EX4400 multigigabit models)

None

4 logical 50-Gbps VCP interfaces using the two 100-Gbps QSFP28 ports on the rear panel (PIC slot 1)

None

EX4500 and EX4550

Two ports on the Virtual Chassis module

None

Any SFP, SFP+, or XFP uplink module port

Note: You cannot use SFP+ uplink ports installed with 1000BASE-T copper SFP transceivers (EX-SFP-1GE-T) as VCP connections on EX4500 and EX4550 switches.

EX4600

None

None

Any SFP+ and QSFP+ ports

EX4650

None

None

Any of the 40-Gigabit Ethernet or 100-Gigabit QSFP28 ports on the front panel (ports 48 through 55), non-channelized

Note: The Junos OS doesn’t prevent you from trying to set other ports as VCPs, but they don’t operate properly as VCPs.

QFX3500 and QFX3600

None

None

Any non-channelized 40-Gigabit Ethernet QSFP+ interfaces

QFX5100

None

None

Any non-channelized 40-Gigabit Ethernet QSFP+ interfaces

QFX5110

None

None

Any 40-Gigabit Ethernet or 100-Gigabit Ethernet QSFP28 ports

Any non-channelized 40-Gigabit Ethernet QSFP+ interfaces

Any non-channelized 10-Gigabit Ethernet SFP+ interfaces (on QFX5110 switch models that support these ports)

QFX5120

None

None

(QFX5120-48Y) Any of the eight 40-Gigabit Ethernet or 100-Gigabit Ethernet QSFP+ or QSFP28 ports on the front panel (ports 48 through 55), non-channelized

(QFX5120-48T) Any of the six 40-Gigabit Ethernet or 100-Gigabit Ethernet QSFP+ or QSFP28 ports on the front panel (ports 48 through 53), non-channelized

Note: Any ports other than those specified above for QFX5120-48Y and QFX5120-48T switches are not supported as VCPs. The Junos OS CLI doesn’t return an error if you try to set other ports as VCPs, but they will not work properly as VCPs.

 (QFX5120-32C) Any non-channelized network ports (ports 0 through 31) installed with either 40-Gbps QSFP+ or 100-Gpbs QSFP28 transceivers

QFX5200

None

None

Any 40-Gigabit Ethernet QSFP+ ports

Starting in Junos OS Release 17.3R2-S4, you can also use 100-Gigabit Ethernet QSFP28 ports as VCPs on QFX5200 switches.
