Starting Interface Configuration (ASA 5510 and Higher)
Detailed Steps
Command Purpose
Step 1
interface physical_interface
Example:
hostname(config)# interface
gigabitethernet 0/0
Specifies the interface you want to configure.
where the physical_interface ID includes the type, slot, and port
number as type[slot/]port.
The physical interface types include the following:
• ethernet
• gigabitethernet
• tengigabitethernet
• management
Enter the type followed by slot/port, for example,
gigabitethernet0/1 or ethernet 0/1. A space is optional between
the type and the slot/port.
Step 2
(Optional)
media-type sfp
Example:
hostname(config-if)# media-type sfp
Sets the media type to SFP, if available for your model. To restore
the default RJ-45, enter the media-type rj45 command.
Step 3
(Optional)
speed {auto | 10 | 100 | 1000 |
nonegotiate}
Example:
hostname(config-if)# speed 100
Sets the speed.
For copper interfaces, the default setting is auto.
For SFP interfaces, the default setting is no speed nonegotiate,
which sets the speed to the maximum speed and enables link
negotiation for flow-control parameters and remote fault
information. The nonegotiate keyword is the only keyword
available for SFP interfaces. The speed nonegotiate command
disables link negotiation.
Step 4
(Optional)
duplex {auto | full | half}
Example:
hostname(config-if)# duplex full
Sets the duplex for copper interfaces. The auto setting is the
default.
Note The duplex setting for an EtherChannel interface must be
Full or Auto.
