Product features
The ExtremeSwitching VDX 6740 product family includes three top-of-rack, Gigabit Ethernet (GbE) line-rate, low latency, lossless Data
Center Bridging (DCB) devices:
The VDX 6740 has the following features:
• Base models support 24 Ethernet ports. A 10G Port Upgrade license can add ports in increments of 8, 16, and 24 ports, for a
total of 48 Ethernet ports. The following types of optics can be installed in these ports:
– 1/10 GbE ports operating at 1 Gbps, 10 Gbps, or in auto-sensing mode (1 or 10 Gbps).
– 1 GbE copper optics, operating at 1 Gbps and 100 Mbps.
– 8 Gbps Fibre channel optics operating at 2, 4, and 8 Gbps and 16 Gbps optics operating at 4, 8, and 16 Gbps when the
FlexPort feature is used.
• Base models do not support 40 GbE ports, but a 40G Port Upgrade license can add two or four 40 GbE ports. Only 4x10
GbE QSFP+ optics can be installed in these ports as FlexPort is not supported on the 40 GbE ports.
The VDX 6740T has the following features:
• Base models support 24 Ethernet ports. A 10G Port Upgrade license can add ports in increments of 8, 16, and 24 ports, for a
total of 48 Ethernet ports. These ports support Base-T (RJ-45) transceivers operating at 100 Mbps, 1 Gbps, 10 Gbps, or in
auto-sensing mode.
• Base models do not contain 40 GbE ports, but a 40G Port Upgrade license can add two or four 40 GbE ports. These ports
support the following optics:
– 40 GbE optics
– 4x10 GbE QSFP+ optics.
– 4x16 Fibre Channel QSFP+ optics if the FlexPort feature is used. Fibre Channel operation is supported on 40-GbE ports
configured in SFP breakout mode (also referred to as 4x10 GbE breakout mode) that use qualified 4x16 Fibre Channel
QSFP+ optics.
The VDX 6740T-1G variant has the following features:
• Base models are fully populated with 48 Ethernet ports. These ports support Base-T (RJ-45) transceivers operating at 100
Mbps, 1 Gbps, or in auto-sensing mode. A 10G Port Upgrade license enables port operation at 100 Mbps, 1 Gbps, 10 Gbps,
or in auto-sensing mode. This upgrade can be installed in increments of 16, 32, and 48 ports.
• Base models contain two 40 GbE ports. A 40G Port Upgrade license can be added for two additional 40 GbE ports. These
ports support the following optics:
– 40 GbE optics
– 4x10 GbE QSFP+ optics.
– 4x16 Fibre Channel QSFP+ optics if the FlexPort feature is used. Fibre Channel operation is supported on 40-GbE ports
configured in 40 GbE mode that use qualified 4x16 Fibre Channel QSFP+ optics.
For all models, the 40 GbE port can be reconfigured as four 10 GbE ports in SFP breakout mode (also referred to as 4x10 GbE
breakout mode). Thus, the device can be configured with as many as 64 10 GbE ports. For instructions on configuring breakout mode,
refer to the "SFP breakout" section of the Extreme Network OS Management Configuration Guide.
