Connecting A Qfx5100 Device In A Virtual Chassis Fabric - Juniper QFX5110 Series Hardware Documentation

Connecting a QFX5100 Device in a Virtual Chassis Fabric

The role of a QFX5100 device in a VCF is dependant on the other switch models used in the VCF
configuration. To understand the different hardware configurations supported, see
Hardware Overview" on page
You can install a VCF in a single rack, multiple racks, or in wire closets. You construct a QFX5100 VCF by
cabling and then configuring SFP+ or QSFP+ interfaces into Virtual Chassis ports (VCPs). All non-channelized
QSFP+ uplink interfaces on QFX5100 switches can be configured into VCPs. All fixed SFP+ interfaces on
QFX5100-96S switches can also be configured into VCPs.
BEST PRACTICE:
Figure 80 on page 295 shows QFX5100 devices in the leaf role in a QFX5110 VCF, while
Figure 81 on page 296 shows QFX5100-24Q in the spine role in a QFX5100 VCF. The cabling in these
examples all used QSFP+ ports as VCPs.

Use 40-Gigabit QSFP+ ports as VCPs.
