Invoking Shared-Backplane Uplink Mode on

Supervisor Engine 6-E and Supervisor Engine 6L-E

This feature enables you to use all four 10-Gigabit Ethernet ports on the supervisor engines as blocking
ports when in redundant mode.
Prior to Cisco IOS Release 12.2(40)SG, Catalyst 4500 Supervisor Engine V-10GE allowed you to enable
either the dual wire-speed 10-Gigabit Ethernet ports or four TwinGig convertor based Gigabit Ethernet
SFP uplink ports when operating in redundant mode.
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
