Using the Web Interface
3.1 Purpose
The Web Management Interface chapter describes how to use your web browser to
manage the a Cisco router.
The Web Management Interface is designed for individuals who prefer a GUI program, or
who are familiar with web-based navigational principles. The Web Browser Interface
enables you to set some configuration parameters in the browser, and to view other settings.
The view-only functionalities are marked as Display Only.
Internet Explorer 2.0 from Microsoft is incompatible with the Cisco 67x router. You must
use Netscape 3.01 or higher or Internet Explorer 3.01 or higher for the Cisco Web
Management Interface.
Note The Web Management Interface may not be available for certain Cisco 67x
configurations. Contact your service provider if you have questions concerning this feature.

3.2 Before Using the Web Management Interface
You must receive an IP address to access the Cisco 67x web management page and a user
password from a support representative before you can use the Web Management Interface.
The IP address for the web management home page is the same as the Eth0 IP address
assigned by your Service Provider (SP).
The user password comes in two modes: Exec, or read-only, and Enable. You must have
Enable privileges to save changes made via the Web interface to NVRAM.
You must click on the Submit Changes button and issue a write command (at the command
line interface) to apply any changes though the Web Management Interface.
Do the following to write to NVRAM.
Step 1 Close the web interface.
Step 2 Logon to the CBOS using either the serial or Telnet interfaces.
Step 3 Write changes to NVRAM:
cbos>write
Step 4 Reboot the system.
cbos>reboot
The system disregards all changes when rebooted if you have not written the changes to
NVRAM.
3.3 Activating the Web Management Interface
Do the procedure below to activate the Web Management Interface.
Step 1 Logon to CBOS using either a serial or telnet interface.
Step 2 Enter the user nameexec orenable and pressEnter to bypass the initial
password if you have not yet created a password. If you have already created a
password, proceed to Step 6.
Step 3 To set a new password for the exec login, enter:
cbos>set password exec new-password
Set a new password for user logins by substitutingenableforexecin the above
example.

78-6599-01 04/09/99 Using the Web Interface 3
Step 4 To save the new password, enter:
cbos>write
Step 5 Enable the Web Management Interface
cbos>set web enabled
Step 6 Launch your preferred web browser.
Step 7 Enter the IP address for the Cisco 67x Web Management page in the browser
locator field. For example, instead ofhttp//www.cisco.com/ insert the
dotted decimal format (http://10.0.0.1/) of the Cisco 67x IP address. The
following screen appears:
Figure 3-1 Password Verification
Step 8 Enter the user name and the password.
Step 9 Once the Web Management Interface home page appears, you should add a
bookmark in your browser for the new Cisco 67x location. Once the bookmark
has been added, simply activate the bookmark to access the Web Management
Interface. Figure 6-2, on page 6-4 shows the interface home page.
Note If you have a exec-only password, all screens are greyed out so that you cannot make
changes.

Cisco Broadband Operating System User Guide 3-13
3 Using the Web Interface 78-6599-01 04/09/99
Step 4 Select either the allow or deny option from the drop down menu. The allow
option allows the specified filter to accept packets from a particular IP address.
The deny option does not permit these packets to flow to a particular IP address.
Step 5 Enter the source address and netmask of where the packet is originating. The
source address is the IP address of the source computer from which you will
allow or deny traffic. The source netmask is the source network from which you
will allow or deny traffic. By entering a source netmask, you can filter a group
of incoming IP addresses.
Step 6 Enter the destination address and netmask. The destination address is the IP
address of the computer that, if allowed, will receive packets originating from
the source IP address. The destination netmask is the destination network that,
if allowed, will receive packets originating from the source netmask. By entering
a destination netmask, you can filter a group of outgoing IP addresses.
Step 7 Select the interface that this filter affects from the drop down menu. Select the
all option for all interfaces.
Step 8 Select the TCP/UDP Port this affects from the drop down menu. Select 0 for all
ports.
Note You must click the Submit Changes button to save the routing changes to NVRAM.
Also, once you change an IP address, you should reboot the Cisco 67x to bind the new IP
addresses to the ports.
