Understanding QFX3000-G QFabric System Hardware Configurations

 

The QFX3000-G QFabric system is made up of multiple hardware components:

  • EX4200 switches—Eight EX4200 switches are required for a QFX3000-G QFabric system. The EX4200 switches are divided into two Virtual Chassis configurations with four switches each.

    • Up to 192 Gigabit Ethernet RJ-45 ports on each Virtual Chassis provide control plane and management network interconnection.

    • Four 10-Gigabit Ethernet uplink ports on each Virtual Chassis interconnect the two Virtual Chassis configurations.

  • QFX3100 Director devices—Two QFX3100 Director devices are required for a QFX3000-G QFabric system. Together, the two Director devices are called a Director group.

    • Six Gigabit Ethernet RJ-45 or six small-form factor pluggable (SFP) ports on each QFX3100 Director device provide connection to the control plane and management network through the Virtual Chassis.

    • Two Gigabit Ethernet RJ-45 or two SFP ports on each QFX3100 Director device interconnect two Director devices in a Director group.

    • One Gigabit Ethernet RJ-45 management port on each QFX3100 Director device provides connection to the management network through your out-of-band management network.

  • QFX3500 , QFX3600, and QFX5100-48S, QFX5100-48T, and QFX5100-24Q Node devices—Up to 128 Node devices can be connected to the QFX3000-G QFabric system.

    • Note

      Up to eight Node devices can be configured as a network Node group to connect to external networks. See Understanding Node Groups.

    • Four 40-Gbps quad small form-factor pluggable plus (QSFP+) uplink ports on each QFX3500 or QFX5100 Node device connect to the data plane network through the QFX3008-I Interconnect devices. Models QFX5100-48S, QFX5100-48T, and QFX5100-24Q are supported as a QFX5100 Node device.

    • Two to eight 40-Gbps QSFP+ uplink ports on each QFX3600 or QFX5100 Node device connect to the data plane network through the QFX3008-I Interconnect devices.

      Note

      On QFX3600 the four QSFP+ ports (Q0 through Q3 are configured as uplink ports by default.

    • Two Gigabit Ethernet RJ-45 or two SFP ports on each Node device provide connection to the control plane and management network through the Virtual Chassis.

      Note

      All models of the QFX5100 have at least one RJ-45 port C0 and an SFP cage (C1). Some QFX5100 SKUs have an additional SFP cage. The SFP cages can be configured for either 1 GbE copper or fiber SFP transceivers. For details on the number of management ports on QFX5100 SKUs, see QFX5100 Device Models.

  • QFX3008-I Interconnect devices—Two QFX3008-I Interconnect devices are required for a QFX3000-G QFabric system. Up to four QFX3008-I Interconnect devices can be used in a QFX3000-G QFabric sysem.

    • Up to 128 40-Gbps QSFP+ ports on each QFX3008-I Interconnect device connect the QFX3500 and QFX3600 Node devices to the data plane network across fiber-optic cables and a high-speed backplane.

    • Up to eight Gigabit Ethernet SFP+ interfaces (four per Control Board) connect each QFX3008-I Interconnect device to the control plane and management network through the Virtual Chassis.
