Limitation and Restrictions on Supervisor Engine 7-E and Supervisor Engine
• Memory utilization for the device is calculated using a combination of the show memory location active and the show
memory location active-dc commands. With a daughter card enabled on Supervisor Engine 8-E, the CLI output for the
command show memory location active-dc shows the value 0 for the config total as no configuration is stored in the
daughter card.
Limitation and Restrictions on Supervisor Engine 7-E and
Supervisor Engine 7L-E
When you use WS-X45-SUP7-E in RPR or SSO mode, only the first two uplinks on each supervisor engine are available. The
second two uplinks are unavailable.
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.
Note Only two 10-Gigabit Ethernet ports or four 1-Gigabit Ethernet ports can be used on the supervisor
engine.
Note 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.
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.
