Creating An Interface; Configuring A Port And Binding It To An Interface - Cisco ASR 5000 Administration Manual

System Interfaces and Ports
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.

Creating an Interface

Use the following example to create a new interface in a context:
configure
context context_name
Notes:
• Optional: Add the loopback keyword option to the interface name command, to set the interface type
• Optional: Add the secondary keyword to the { ip | ipv6 } address command, to assign multiple IP
• Optional: In the interface config mode, add the port-switch-on-L3-fail address command, to configure

Configuring a Port and Binding It to an Interface

Use the following example configuration to configure and assign a port to an interface:
configure
port ethernet slot#/port#
Notes:
• For port ethernet slot#, use the actual chassis slot in which the line card is installed. This could be any
• For port ethernet port#, on FELCs, this value can be from 1 to 8. For the GELC/GLC2s and XGLCs
• Optional: In the Ethernet Port configuration mode, add the preferred slot slot# command if line card
interface name
{ ip | ipv6 } address address subnetmask

as "loopback" which is always UP and not bound to any physical port.
addresses to the interface. IP addresses can be entered using IPv4 dotted-decimal or IPv6
colon-separated-hexadecimal notation.
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.
