Gigabit Ethernet Management Interface Overview
The router provides an Ethernet management port named GigabitEthernet0.
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
Cisco IOS is down.
•
The management Ethernet interface is part of its own VRF. See the
Cisco ASR 1000 Series Aggregation
Services Routers Software Configuration Guide
for more details.
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.
