Chapter 7 Configuring Interfaces
Selecting the Uplink Port on a Supervisor Engine 7L-E
reload the system to enable Ten Gigabit 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.
Selecting the Uplink Port on a Supervisor Engine 7L-E
With Cisco IOS Release 15.0(2)SG, the SFP+/SFP uplink modes on Supervisor Engine 7L-E
(WS-X45-SUP-7L-E) have changed. The number of uplink ports now depends on the supervisor engine
mode (single or redundant) and the uplink mode configuration (1-Gigabit or 10-Gigabit). To configure
the uplink mode, use the hw-module uplink select [gigabitethernet/ tengigabitethernet] command, as
follows:
Switch(config)# hw-module uplink select?
gigabitethernet Select the gigabit uplinks
tengigabitethernet Select the 10G uplinks
Note Supervisor Engine 7L-E is not supported on a ten-slot chassis. USB device and SD card support is
applicable to Supervisor 7-E only.
Single Supervisor Mode
In single supervisor mode, WS-X45-SUP-7L-E supports the uplink configuration of at most either two
10-Gigabit or four 1-Gigabit ports (Table 7-1).
SFP+ and SFP can be inserted in any order for lines 2 thru 4.
