DETAILED STEPS
Command or Action Purpose
Step 1
enable
Example:
Router> enable
Enables the privileged EXEC mode.
Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters the global configuration mode.
Step 3
service unsupported-transceiver
Example:
Router(config)# service
unsupported-transceiver
Enables third-party SFP support.
Step 4
interface type slot/subslot/port number
Example:
Router(config)# interface ethernet 0/3/0
Selects an interface to configure.
Step 5
media-type sfp
Example:
Router(config-if)# media-type sfp
Changes media type to SFP.
Step 6
speed value
Example:
Router(config-if)# speed 100
Configures the speed of the interface.
Note For 100BASE SFPs, configure the
speed to 100 Mbps only. Similarly,
for 1000BASE SFPs, configure
the speed to 1000 Mbps only.
Step 7
shutdown
Example:
Router(config-if)# shutdown
Disables the interface, changing its state
from administratively UP to
administratively DOWN.
