Selecting Uplink Mode on a Supervisor Engine 6-E

You can use the hw-module uplink mode command to change the uplink mode to either
shared-backplane or tengigabitethernet mode.
Only two 10-Gigabit Ethernet ports or four 1-Gigabit Ethernet ports can be used on the supervisor
Note
engine.
When changing the uplink mode using the hw-module uplink mode shared-backplane command, you
Note
must reload the system. A message appears on the console to reflect this.
To select shared-backplane mode, do the following:
Switch(config)# hw-module uplink mode shared-backplane
A reload of the active supervisor is required to apply the new configuration.
Switch(config)# exit
Switch#
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 TenGigabit 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 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 Ten Gigabit mode, the uplink is limited to two Ten Gigabit Ethernet interfaces in
non-redundant and in redundant mode; Gigabit Ethernet 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
TenGigabit mode, preventing you from selecting gigabitethernet mode.
Support for WS-X46490-CSFP-E on a 10-slot Chassis
Starting with Release IOS XE 3.5.0E and IOS 15.2(1)E, the WS-X4640-CSFP-E linecard is supported
in a 10-slot chassis for switch mode stand alone and switch mode virtual (VSS). New configurations are
saved and reloaded so that the new configuration is applied to the entire switch.
To enable support for WS-X4640-CSFP-E on a 10-slot chassis, enter the following:
switch# configuration terminal
switch# hw-module system max-port-num-mode 2
To restore the default mode (Mode 1), you need to enter the following:
switch# configuration terminal
switch# no hw-module system max-port-num-mode 2
