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 Virtual Chassis Fabric Hardware Overview.

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.

Figure 1 shows QFX5100 devices in the leaf role in a QFX5110 VCF, while Figure 2 shows QFX5100-24Q in the spine role in a QFX5100 VCF. The cabling in these examples all used QSFP+ ports as VCPs.
