Ethernet Interfaces and Virtual 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 the
Step 2
Assign a virtual port for use by the interface and bind the port to the interface by applying the example configuration in
the
the
Step 3
Optionally configure a static route for the interface by applying the example configuration in the
Step 4
Repeat the above steps for each interface to be configured.
Important:
Interface configuration requires o ne-to-one mapping between the VPC-VSM virtual
interfaces and the 10 Gbps (tengige) ports on the ASR 9000 RSP. 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 in 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 port. Failure to turn off the
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 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.
