Usage Guidelines When changing the uplink mode using the hw-module uplink mode shared-backplane command, you
must reload the system. A message appears on the console to reflect this.
On a Supervisor Engine 6-E in a 6 or 7-slot chassis (Catalyst 4506-E, 4507R-E, and 4507R+E), the
default uplink mode does not allow a WS-X4640-CSFP-E linecard to boot in the last slot because of a
hardware limitation. After you the hw-module uplink mode tengigabitethernet command, you must
reload the system to enable TenGig mode. The configuration is NVGEN'd after you save the running
configuration to the startup configuration. You can use the show run | incl uplink command to check
the uplink configuration before reloading the system. Furthermore, you can can enter the show
hw-module uplink command to display the uplink mode. It reports the current uplink mode, as well as
the mode after the system reloads.
In uplink TenGig mode, the uplink is limited to two 10-Gigabit Ethernet interfaces in non-redundant and
in redundant mode; Gigabit Etnernet interfaces are not supported. The WS-X4640-CSFP-E linecard
boots in the last slot on 6 and 7-slot chassis. To return to default mode, reload the system from
tengigabitethernet mode. SharedBackplane mode can be selected from Default mode, where a system
reload is required as well.
The hw-module module x port-group x select gigabitethernet command is blocked in uplink TenGig
mode, preventing you from selecting gigabitethernet mode.
