Ethernet Interfaces and Ports
Regardless of the type of application interface, the procedure to create and configure it consists of the following:
Step 1
Create an interface and assign an IP address and subnet mask to it by applying the example configuration in
Step 2
Assign a physical port for use by the interface and bind the port to the interface by applying the example configuration
in
in
Step 3
Step 4
Repeat the above steps for each interface to be configured.
Important:
This section provides the minimum instructions for configuring interfaces and ports to allow the
system to communicate on the network. Commands that configure additional interface or port properties are described
in the Ethernet Port Configuration Mode Commands and Ethernet Interface Configuration Mode Commands chapters
of the Command Line Interface Reference.

of the Command Line Interface Reference.
Caution:
To ensure that system line card and port-level redundancy mechanisms function properly, the
Spanning Tree protocol must be disabled on devices connected directly to any system port. Failure to turn off the
Spanning Tree protocol may result in failures in the redundancy mechanisms or service outage.
Spanning Tree protocol may result in failures in the redundancy mechanisms or service outage.
Creating an Interface
Use the following example to create a new interface in a context:
configure
context context_name
interface name
{ ip | ipv6 } address address subnetmask [ secondary ]
end
Notes:
Optional: Add the loopback keyword option to the interface name command, to set the interface type as
“loopback” which is always UP and not bound to any physical port.
Optional: Add the secondary keyword to the { ip | ipv6 } address command, to assign multiple IP addresses to
the interface. IP addresses can be entered using IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal
notation.
notation.
Optional: In the interface config mode, add the port-switch-on-L3-fail address command, to configure the
interface for switchover to the port on the redundant line card if connectivity to a specified IP address is lost.
This IP address can be entered using IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal notation.
