Cisco ASR 1001-X Router Power Up and Initial Configuration
The purpose of this interface is to allow users to perform management tasks on the router; it is an interface
that should not, and often cannot, forward network traffic, but can be used to access the router via Telnet and
SSH to perform management tasks on the router. The interface is most useful before a router has begun routing,
or in troubleshooting scenarios when other forwarding interfaces are inactive.
The following aspects of the management Ethernet interface should be noted:
• The router has one management Ethernet interface named GigabitEthernet0.
• IPv4, IPv6, and ARP are the only routed protocols supported for the interface.
• The interface provides a way to access the router even if forwarding interfaces are not functional, or the
• The management Ethernet interface is part of its own VRF. See the

Default Gigabit Ethernet Configuration

By default, a forwarding VRF is configured for the interface with a special group named Mgmt-intf. This
cannot be changed. This isolates the traffic on the management interface away from the forwarding plane.
Otherwise, the interface can be configured like other Gigabit Ethernet interfaces for most functions.
For example, the default configuration is as follows
interface GigabitEthernet0
vrf forwarding Mgmt-intf
ip address 172.18.77.212 255.255.255.240
negotiation auto

Configuring Gigabit Ethernet Interfaces

This sections shows how to assign an IP address and interface description to an Ethernet interface on your
router.
