Important Points to Remember
• For 10–Gigabit Ethernet interfaces, CR4 auto-negotiation is not applicable.
• For 100-Gigabit Ethernet interfaces, CR4 auto-negotiation is enabled by default.
• For 40–Gigbit, 25–Gigabit and 50–Gigabit Ethernet interfaces, CR4 auto-negotiation is disabled by default.
Setting the Speed and Duplex Mode of Ethernet
Interfaces
To discover whether the remote and local interface requires manual speed synchronization, and to manually synchronize them if necessary,
use the following command sequence.
1 Determine the local interface status. Refer to the following example.
EXEC Privilege mode
show interfaces [interface | stack—unit stack-unit-number] status
2 Determine the remote interface status.
EXEC mode or EXEC Privilege mode
[Use the command on the remote system that is equivalent to the rst command.]
3 Access CONFIGURATION mode.
EXEC Privilege mode
config
4 Access the port.
CONFIGURATION mode
interface interface-type
5 Set the local port speed.
INTERFACE mode
speed {10 | 100 | 1000 | 10000 | auto}
NOTE
: If you use an active optical cable (AOC), you can convert the QSFP+ port to a 10 Gigabit SFP+ port or 1 Gigabit
SFP port. You can use the speed command to enable the required speed.
6 Optionally, set full- or half-duplex.
INTERFACE mode
duplex {half | full}
7 Disable auto-negotiation on the port.
INTERFACE mode
no negotiation auto
If the speed was set to 1000, do not disable auto-negotiation.
