Setting Up In-Band Management

For in-band management, you must first decide which interface you want as your management interface. Generally, management traffic is not excessive, or even substantial, so picking any of the slower interfaces on your router is likely to be enough. On most devices, a Fast Ethernet connection is more than sufficient to handle management traffic. On lower-end devices, you might choose a serial interface or T1/E1 interface, if there is one.

Connecting the interface is identical to connecting any other interface on the router. Here are the details for using fe-0/1/1 (refer to Chapter 6 for more details on this interface):

1. Connect the cable to the port and ensure that the remote connection is in place.

   When the link lights come up, you're ready to configure the interface.

   Some interfaces, such as serial interfaces, require some minimal configuration before the link is active. For such interfaces, you must configure the interface as you do with any other interface before the link lights come up.

2. After wiring up the management interface, configure the interface so that it has an IP address.

   Typically, this configuration is enough to enable the interface:

   interfaces {
       fe-0/1/1 {
           unit 0 {
               family inet {
                   address 192.168.71.246/32;
               }
           }
       }
   }
   

When you configure an in-band management interface, if you are configuring a Layer 3 device such as a router, you need ...
