Enabling a Physical Interface
After determining the type of physical interfaces available, to enable and configure the interfaces, enter INTERFACE
mode by using the interface interface slot/port command.
1. Enter the keyword interface then the type of interface and slot/port information.
CONFIGURATION mode
interface interface
– For a 10/100/1000 Ethernet interface, enter the keyword GigabitEthernet then the slot/port
information.
– For a Gigabit Ethernet interface, enter the keyword GigabitEthernet then the slot/port information.
– For the Management interface on the RPM, enter the keyword ManagementEthernet then the slot/port
information.
– For a SONET interface, enter the keyword sonet then the slot/port information.
– For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port
information.
– For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
2. Enable the interface.
INTERFACE mode
no shutdown
If the interface is a SONET interface, enter the encap ppp command to enable PPP encapsulation.
To confirm that the interface is enabled, use the show config command in INTERFACE mode. To leave INTERFACE
mode, use the exit command or end command. You cannot delete a physical interface.
Physical Interfaces
The Management Ethernet interface is a single RJ-45 Fast Ethernet port on each unit of the Z9000.
The interface provides dedicated management access to the system.
Line card interfaces support Layer 2 and Layer 3 traffic over the 10/100/1000, Gigabit, and 10-Gigabit Ethernet interfaces.
Synchronous optical network technologies (SONET) interfaces with point-to-point protocol (PPP) encapsulation support
Layer 3 traffic. These interfaces (except SONET interfaces with PPP encapsulation) can also become part of virtual
interfaces such as virtual local area networks (VLANs) or port channels.
For more information about VLANs, refer to Bulk Configuration. For more information on port channels, refer to Port
Channel Interfaces.
FTOS Behavior: The Z9000 system uses a single MAC address for all physical interfaces.
Configuration Task List for Physical Interfaces
By default, all interfaces are operationally disabled and traffic does not pass through them.
