Limitation And Restrictions On Supervisor Engine 7-E And Supervisor Engine 7L-E - Cisco Catalyst 4500 Series Configuration Manual

Limitation and Restrictions on Supervisor Engine 7-E and Supervisor Engine 7L-E

Beginning with Cisco IOS Release 12.2(40)SG, you could deploy all four 10-Gigabit Ethernet ports, two
blocking ports on an active supervisor engine and two blocking ports on the standby supervisor engine,
or all eight Gigabit Ethernet SFP ports, four on the active supervisor and four on the standby supervisor
engine. This capability is supported on all Catalyst 4500 and 4500E series chassis.
To enable shared-backplane mode, enter this command:
Command
Switch(config)# hw-mod uplink mode
shared-backplane
To disable shared-backplane mode, enter this command:
Command
Switch(config)# no hw-mod uplink mode

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

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
