FTOS Configuration Guide for the C-Series - Force10 Networks

When an interface is in either mode, you receive an error message if you try to configure a command that
must be in the other mode. For example, in Figure 156, the command ip address triggered an error
message because the interface is in Layer 2 mode and the ip address command is a Layer 3 command.
Figure 156 Error Message When Trying to Add an IP Address to Layer 2 Interface

To determine the configuration of an interface, you can use show config command in the INTERFACE
mode or the various show interfaces commands in the EXEC mode.
Interface Types
This section contains the following major sections:
• Physical Interfaces on page 247

• Management Interface on the E-Series and C-Series on page 252
• Management Interface on the S-Series on page 254
• Loopback Interfaces on page 254
• Null Interface on page 255
• Port Channel Interfaces on page 255

Physical Interfaces
10/100/1000 Ethernet, Gigabit Ethernet and 10 Gigabit Ethernet interfaces are supported on platforms:
c e s
SONET interfaces are supported only on platform e
Error message
Another interface, found on the Route Processor Module (RPM) of the C-Series and E-Series, is the
Management Ethernet interface. This interface type is Fast Ethernet and provides dedicated management
access to the system. The S-Series 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.
