Interfaces | 287
To enter the INTERFACE mode, use these commands in the following sequence, starting in the
CONFIGURATION mode:
To confirm that the interface is enabled, use the
show config command in the INTERFACE mode.
To leave the INTERFACE mode, use the
exit command or end command.
The user can not delete a physical interface.
Physical Interfaces
The Management Ethernet interface, is a single RJ-45 Fast Ethernet port on the Route Processor Module
(RPM) of the C-Series and E-Series and on each unit of the S55; it provides dedicated management access
to the system. The other S-Series (non-S55) systems supported by FTOS do not have this dedicated
management interface, but you can use any Ethernet port configured with an IP address and route.
Line card interfaces support Layer 2 and Layer 3 traffic over the 10/100/1000, Gigabit, and 10-Gigabit
Ethernet interfaces. SONET interfaces with PPP encapsulation support Layer 3 traffic. These interfaces
(except SONET interfaces with PPP encapsulation) can also become part of virtual interfaces such as
VLANs or port channels.
Link detection on ExaScale line cards is interrupt-based rather than poll-based, which enables ExaScale
cards to bring up and take down links faster.
Step Command Syntax Command Mode Purpose
1
interface interface CONFIGURATION Enter the keyword interface followed by the type of interface
and slot/port information:
• For a 10/100/1000 Ethernet interface, enter the keyword
GigabitEthernet followed by the slot/port information.
• For a Gigabit Ethernet interface, enter the keyword
GigabitEthernet followed by the slot/port information.
• For the Management interface on the RPM, enter the
keyword ManagementEthernet followed by the slot/port
information.
• For a SONET interface, enter the keyword
sonet followed
by slot/port information.
• For a 10 Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet followed by the slot/port
information.

no shutdown
INTERFACE Enter the no shutdown command to enable the interface. If
the interface is a SONET interface, enter the encap ppp
command to enable PPP encapsulation.
