Gigabit Ethernet Management Interface Overview
The chassis has one Gigabit Ethernet Management Ethernet interface on each Route Switch Processor.
The purpose of this interface is to allow users to perform management tasks on the router; it is basically an interface that should not and often cannot forward network traffic but can otherwise access the router, often via Telnet and SSH, and perform most management tasks on the router. The interface is most useful before a router has begun routing, or in troubleshooting scenarios when the interfaces are inactive.
The following aspects of the Management Ethernet interface should be noted:
- Each RSP has a Management Ethernet interface, but only the active RSP has an accessible Management Ethernet interface (the standby RSP can be accessed using the console port, however).
- IPv4, IPv6, and ARP are the only routed protocols supported for the interface.
- The interface provides a method of access to the router even if the interfaces or the IOS processes are down.
- The Management Ethernet interface is part of its own VRF. For more information, see the Gigabit Ethernet Management Interface VRF.
