To install and configure Embedded CiscoView, perform the following steps:

 

Command

 

Purpose

Step 1

 

 

Router# dir device_name

Displays the contents of the device.

 

 

 

 

 

If you are installing Embedded CiscoView for the first

 

 

 

 

 

time, or if the CiscoView directory is empty, skip to

 

 

 

 

 

Step 4.

Step 2

 

 

Router# delete device_name:cv/*

Removes existing files from the CiscoView directory.

Step 3

 

 

Router# squeeze device_name:

Recovers the space in the file system.

Step 4

 

 

Router# archive tar /xtract tftp://

Extracts the CiscoView files from the tar file on the TFTP

 

ip address of tftp server/ciscoview.tar

server to the CiscoView directory.

 

device_name:cv

 

Step 5

 

 

Router# dir device_name:

Displays the contents of the device.

 

 

 

 

 

In a redundant configuration, repeat Step 1 through

 

 

 

 

 

Step 5 for the file system on the redundant supervisor

 

 

 

 

 

engine.

Step 6

 

 

Router# configure terminal

Enters global configuration mode.

Step 7

 

 

Router(config)# ip http server

Enables the HTTP web server.

Step 8

 

 

Router(config)# snmp-server community string ro

Configures the SNMP password for read-only operation.

Step 9

 

 

Router(config)# snmp-server community string rw

Configures the SNMP password for read/write operation.

 

 

 

 

 

 

 

 

 

 

 

 

 

Note

The default password for accessing the switch web page is the enable-level password of the switch.
