Common Ethernet Management Tasks, Viewing the VRF Configuration

Page 291 highlights

Chapter 9 Using the Management Ethernet Interface Common Ethernet Management Tasks • Prevents transit traffic from traversing the router. Because all of the SPA interfaces and the Management Ethernet interface are automatically in different VRFs, no transit traffic can enter the Management Ethernet interface and leave a SPA interface, or vice versa. • Improved security of the interface. Because the Mgmt-intf VRF has its own routing table as a result of being in its own VRF, routes can only be added to the routing table of the Management Ethernet interface if explicitly entered by a user. The Management Ethernet interface VRF supports both IPv4 and IPv6 address families. Common Ethernet Management Tasks Because users can perform most tasks on a router through the Management Ethernet interface, many tasks can be done by accessing the router through the Management Ethernet interface. This section documents tasks that might be common or slightly tricky on the Cisco ASR 1000 Series Routers. It is not intended as a comprehensive list of all tasks that can be done using the Management Ethernet interface. This covers the following processes: • Viewing the VRF Configuration, page 9-3 • Viewing Detailed VRF Information for the Management Ethernet VRF, page 9-4 • Setting a Default Route in the Management Ethernet Interface VRF, page 9-4 • Setting the Management Ethernet IP Address, page 9-4 • Telnetting over the Management Ethernet Interface, page 9-5 • Pinging over the Management Ethernet Interface, page 9-5 • Copy Using TFTP or FTP, page 9-5 • NTP Server, page 9-5 • SYSLOG Server, page 9-6 • SNMP-Related Services, page 9-6 • Domain Name Assignment, page 9-6 • DNS service, page 9-6 • RADIUS or TACACS+ Server, page 9-6 • VTY lines with ACL, page 9-7 Viewing the VRF Configuration The VRF configuration for the Management Ethernet interface is viewable using the show running-config vrf command.

Using the Management Ethernet Interface
Common Ethernet Management Tasks
Prevents transit traffic from traversing the router. Because all of the SPA interfaces and the
Management Ethernet interface are automatically in different VRFs, no transit traffic can enter the
Management Ethernet interface and leave a SPA interface, or vice versa.
Improved security of the interface. Because the Mgmt-intf VRF has its own routing table as a result
of being in its own VRF, routes can only be added to the routing table of the Management Ethernet
interface if explicitly entered by a user.
The Management Ethernet interface VRF supports both IPv4 and IPv6 address families.
Common Ethernet Management Tasks
Because users can perform most tasks on a router through the Management Ethernet interface, many
tasks can be done by accessing the router through the Management Ethernet interface.
This section documents tasks that might be common or slightly tricky on the Cisco ASR 1000 Series
Routers. It is not intended as a comprehensive list of all tasks that can be done using the Management
Ethernet interface.
