Chassis and Modules
describes the hardware requirements for the VSS chassis and modules.
VSL Hardware Requirements
The VSL EtherChannel supports only 10-Gigabit Ethernet ports. The 10-Gigabit Ethernet port can be
located on the supervisor engine module or on one of the following switching modules:
•
WS-X6708-10G-3C or WS-X6708-10G-3CXL
•
WS-X6716-10G-3C or WS-X6716-10G-3CXL
•
WS-X6716-10T-3C or WS-X6716-10T-3CXL
Note
•
Using the 10-Gigabit Ethernet ports on a WS-X6716-10G switching module in the VSL
EtherChannel requires Cisco IOS Release 12.2(33)SXI or a later release.
•
Using the 10-Gigabit Ethernet ports on a WS-X6716-10T switching module in the VSL
EtherChannel requires Cisco IOS Release 12.2(33)SXI4 or a later release.
We recommend that you use both of the 10-Gigabit Ethernet ports on the supervisor engines to create
the VSL between the two chassis.
You can add additional physical links to the VSL EtherChannel by using the 10-Gigabit Ethernet ports
on WS-X6708-10G, WS-X6716-10G, or WS-X6716-10T switching modules.

VSS Hardware Requirements
Hardware
Count Requirements
Chassis
2
The VSS is available on chassis that support VS-S720-10G supervisor
engines and WS-X6708-10G switching modules.
Note
The two chassis need not be identical.
Supervisor Engines
2
The VSS requires Supervisor Engine 720 with 10-Gigabit Ethernet ports.
You must use either two VS-S720-10G-3C or two VS-S720-10G-3CXL
supervisor engine modules.
The two supervisor engines must match exactly.
Switching Modules
2+
The VSS requires 67xx series switching modules.
The VSS does not support classic, CEF256, or dCEF256 switching
modules. In virtual switch mode, unsupported switching modules remain
powered off.
