Chapter3 Starting and Configuring Configuring a Cisco7401ASR Router

--- System Configuration Dialog ---

At any point you may enter a question mark '?' for help.

Use ctrl-c to abort configuration dialog at any prompt.

Default settings are in square brackets '[]'.

Step2 When asked if you want to enter the initial configuration dialog and see the current interface summary,

enter yes or press Return:

Would you like to enter the initial configuration dialog? [yes]:

First, would you like to see the current interface summary? [yes]:

In the following example, the summary shows a Cisco 7401ASR router at first-time startup; that is,

nothing is configured.

Any interface listed with OK? value "NO" does not have a valid configuration

Interface IP-Address OK? Method Status Protocol

ATM1/0 unassigned NO unset down down

FastEthernet2/0 unassigned NO unset down down

Step3 Choose which protocols to support on your interfaces. For Internet Protocol (IP)-only installations, yo u

can accept the default values for most of the questions. A typi cal configu rat ion u si ng IP, IPX, and

AppleTalk follows and continues through Step 8:

Configuring global parameters:

Enter host name [Router]:

Step4 Enter enable secret, enable, and virtual terminal passwords:

The enable secret password is a one-way cryptographic secret

password used instead of the enable password when it exists.

Enter enable secret: barney

The enable password is used when there is no enable secret

password and when using older software and some boot images.

Enter enable password: betty

Enter virtual terminal password: fred

Step5 The Simple Network Management Protocol (SNMP) is the most widely supported open standard for

network management. It provides a means to access and set configurat ion and ru n-t ime p ar ame ters of

routers and communication servers. SNMP defines a set of functions that can be used to monitor and

control network elements.

Enter yes or press Return to accept SNMP management; enter no to refuse it:

Configure SNMP Network Management? [yes]:

Community string [public]:

Step6 For the following queries, do not enable VINES, LAT, DECnet, CLNS, bridging, XNS, or Apollo:

Configure Vines? [no]:

Configure LAT? [no]:

Configure DECnet? [no]:

Configure CLNS? [no]:

Configure bridging? [no]:

Configure XNS? [no]:

Configure Apollo? [no]:
