Cisco | 1005 - 1005 Router | Using the Cisco Web Browser

Using the Cisco Web Browser
The Cisco IOS software includes a Web browser from which you can issue Cisco IOS commands.
This Cisco IOS feature is accessed from the router’s home page and can be customized for your
business environment. For example, you can view pages in different languages and save them in
Flash memory for easy retrieval. You can also configure the Web Cache Control Protocol (WCCP)
to handle Web traffic and increase the efficiency of your time spent on the Web.
For a complete description of the Cisco Web browser configuration commands in this chapter, refer
to the “Cisco Web Browser Commands” chapter of the Configuration Fundamentals Command
Reference. To locate documentation of other commands that appear in this chapter, use the command
reference master index or search online.
Cisco Web Browser Task List
Use of the Cisco Web browser is optional. To use and customize the Cisco Web browser, complete
the tasks in the following sections:

Configure the Web Cache Control Protocol
Use the Cisco Web Browser Interface to Issue Commands
You can issue most of the Cisco IOS commands using a Web browser. This Cisco IOS feature is
accessed by using the Cisco Web browser interface, which is accessed from the router’s home page.
(All Cisco routers and access servers loaded with the latest version of Cisco IOS software have a
home page, which is password protected.)
From the router’s home page, you click on a hypertext link titled “Monitor the Router.” This link
takes you to a Web page that has a “Command” field. You can type commands in this field as if you
were entering commands at a terminal connected to the router. The page also displays a list of
commands. You can execute these commands by clicking on them, as if you were clicking on
hypertext links.

Use the Correct Hardware and Software
To use the Cisco Web browser interface, your computer must have a World Wide Web browser. The
Cisco Web browser interface works with most browsers, including Netscape Navigator. Your Web
browser must be able read and submit forms. The original versions of Mosaic might have problems
using the Cisco Web browser interface, because they either cannot submit forms or have difficulty
doing so.
The computer must be connected to the same network that the router or access server is on.
Access Your Router’s Home Page
Cisco IOS software allows users with a default privilege level of 15 to access a predefined home page
for a router or access server. If you have been assigned a privilege level other than 15, Cisco IOS
Release 11.3 or later software allows you to issue Cisco IOS commands from a Web page where the
commands defined for your specific user privilege level will be displayed.
To access the home page for your router or access server with a default privilege level of 15, perform
the following steps:
Step 1
Enter the following command in the URL field of your Web browser and press return:
http://router-name/. (For example, to access a Cisco router named cacophony with a
default privilege level of 15, type http://cacophony/.)The browser then prompts you for
the password.
Step 2
Enter the password.
Note The name and password for your router and access server are designated in their
configuration. Contact your network administrator if you do not have this information.
The browser should display the home page for your router or access server.
The router’s home page looks something like the Cisco 7200 home page shown in Figure 8.
Using the Cisco Web Browser FC-109
Use the Cisco Web Browser Interface to Issue Commands
Figure 8
Example of a Home Page for a Cisco 7200
To access a router Web page for a preassigned privilege level other than the default of 15, perform
the following steps:
Step 1
Enter the following command in the URL field of your Web browser and press return:
http://router-name/level/level/mode/command. (For example, to request a user privilege
level of 12 on a Cisco router named cacophony, type http://cacophony/level/12/exec).The
browser then prompts you for the username and/or password.
Step 2
Depending on your authentication method, enter your username and/or password and
press return. The Web browser should display a Web page specific to your user privilege
level, mode, and the command you have requested.
Table 10 lists the URL arguments you must use when requesting a Web page.

level.
Issue Commands Using the Cisco Web Browser Interface
To issue commands using the Cisco Web browser interface, click the link “Monitor the router” in the
first list of hypertext links on the home page. This displays the Web page shown in Figure 9.

To enter a command using hypertext links, scroll through the commands listed at the bottom of the
screen and click the one you want to execute. If the link is a complete command, it is executed. If
the command has more parameters, another list of command hypertext links is displayed. Scroll
through this second list and click the one you want to execute.
If the command is a request for information, like a show command, the information is displayed in
the Web browser window.
If the command requires a variable, a form in which you can enter the variable is displayed.
Using the Cisco Web Browser FC-111
Customize the User Interface on a Web Browser
Enter Commands Using the Command Field
Entering the command in the command field is just like entering it at a terminal console. Enter the
command using the syntax documented in the Cisco IOS command reference. If you are uncertain
of the options available for a particular command, type a question mark (?).
For example, entering show ? in the command field displays the parameters for the show command.
The Cisco Web browser interface displays the parameters as hypertext links. To select a parameter,
you can either click on one of the links, or you can enter the parameter in the command field.
Enter Commands Using the URL Window
You can issue a command using the URL window for the Web browser.
For example, to execute a show configuration command on a router named example, you would
enter the following in the URL window:
http://example/exec/show/configuration
The Web browser then displays the configuration for the “example” router. To save effort, modify
the URL in the URL window in the browser control bar instead of retyping the entire URL.
The difference between entering a command in the command field and entering a command in the
URL window is that in the URL window, command modes, keywords, and options should be
separated by slashes, not spaces.
Customize the User Interface on a Web Browser
You can customize HTML pages to display Cisco IOS command output and Cisco IOS
platform-specific variables (for example, a router host name or router address typically used in router
setup pages) for a Web browser. You can display this information using HTML formatted Server
Side Includes (SSIs) that you insert into your custom HTML pages. SSIs are a Cisco IOS software
feature described in the following sections.
Definition of SSIs
SSIs are HTML formatted commands or variables that you insert into HTML pages when you
customize Cisco IOS platform configuration pages for a Web browser. These SSI commands and
SSI variables display Cisco IOS command output and Cisco IOS platform-specific variables.
The Cisco IOS software supports two HTML SSI commands defined for customizing HTML pages:
the SSI EXEC command and the SSI ECHO command. The HTML format of the
SSI EXEC command is <!--#exec cmd=“xxx”-->, and the HTML format of the
SSI ECHO command is <!--#echo var=“yyy”-->. (See the section “Customize HTML Pages Using
SSIs” later in this chapter for a description of how to use these commands).
In addition to the two SSI commands, the Cisco IOS software supports several SSI variables defined
for customizing HTML pages. SSI variables are used with the SSI ECHO command. There is one
SSI variable defined for all Cisco IOS platforms (SERVER_NAME) and other SSI variables
specifically defined for ISDN, Frame Relay, and asynchronous serial platforms. The format and a
description of all the available SSI variables are provided in Table 5. (See the section “Customize
HTML Pages Using SSIs” later in this chapter for a description of how to use these SSI variables
with the SSI ECHO command).
The SSI EXEC command is supported on all platforms. The SSI ECHO command, used with SSI
variables, is supported on all platforms listed in Table 11.

Using the Cisco Web Browser FC-113
Customize the User Interface on a Web Browser
How SSIs Work
Once you have designed a set of HTML pages that include SSIs, you can copy these pages to a
Cisco IOS platform’s Flash memory. (See the section “Copy HTML Pages to Flash Memory” for
instructions on storing HTML pages in Flash memory later in this section.) When you retrieve these
pages from Flash memory and display them using a Web browser, any SSI command that was
designed into these pages will either display Cisco IOS command output or display a current
variable or identifier defined in Table 9. For example, the SSI ECHO command with the variable
SERVER_NAME will display the current host name of the HTTP server you are using, and the
SSI ECHO command with the variable EZSETUP_ISDN_SWITCHTYPE will display the current
ISDN switch type you are using.
Benefits of Customizing Web Pages with SSIs
Using SSIs, you can customize one set of international HTML pages (for example, in Japanese) and
copy these pages to Flash memory on multiple Cisco IOS platforms. When you retrieve these pages
from the Flash memory of a Cisco IOS platform, current variables and identifiers associated with the
platform you are currently using are displayed. SSIs save you from having to duplicate these
international pages (considered relatively large images that contain 8-bit or multibyte characters)
and store them in the source code for each platform you are using. (Refer to Table 9 to determine
which Cisco IOS platforms support which SSIs variables.)

with a Cisco IOS command that can be executed in the router’s EXEC mode. (See the “SSI EXEC
Command Example” section later in this chapter.)
When you are customizing an HTML page for a Web browser, type <!--#echo var=“yyy”--> in your
HTML file where you want a value or identifier associated with a particular Cisco IOS platform (for
example, an ISDN or Frame Relay platform) to appear on the browser page. Replace yyy with an
SSI variable described in Table 9. (See the “SSI ECHO Command Example” section later in this
chapter.)
FC-114
Configuration Fundamentals Configuration Guide
Copy HTML Pages to Flash Memory
Copy HTML Pages to Flash Memory
Once you have customized HTML pages using SSIs, copy your HTML pages to a Cisco IOS
platform’s Flash memory. To do this, save your pages using a filename appended with “.shtml” (for
example, filename.shtml) and copy your file to Flash memory using a copy command (for example,
the copy tftp flash command). (Refer to the Cisco IOS command references for a copy command
compatible with your Cisco IOS platform.)
Enable the Cisco Web Browser Interface
To view the HTML pages you have just customized, you must first enable the Cisco Web browser
interface. To enable the Cisco Web browser interface, use the following command in global
configuration mode:
Command
Purpose
ip http server
Enable the Cisco Web browser interface.
Refer to the section “Configure the Cisco Web Browser Interface” earlier in this chapter for further
information on configuring the Cisco Web browser interface.
View Your HTML File Containing SSIs
Once the Cisco Web browser interface is enabled, you can retrieve your HTML page from Flash
memory and view it on the Cisco Web browser by typing the URL http://router/flash/filename in
the URL window. Replace router with the host name or IP address of the current Cisco IOS platform
you are using, and replace filename with the name of the file you created with “.shtml” appended.
For example, http://myrouter/flash/ssi_file.shtml.
Display 8-bit and Multibyte Character Sets
Your Cisco IOS platform will automatically display 8-bit and multibyte character sets and print the
ESC character as a single character instead of as the caret and bracket symbols (^[) when the Cisco
Web browser interface is enabled with the ip http server command.
If you are Telneting to a Cisco IOS platform, use the following command in line configuration mode
to display 8-bit and multibyte international character sets and print the ESC character as a single
character instead of “^[”:
Command
Purpose
international
Configure a router to display 8-bit and multibyte international character sets and
print the ESC character as a single character instead of “^[” when Telneting to a
Cisco IOS platform.
If you are Telneting to a Cisco IOS platform, use the following command in EXEC mode to display
8-bit and multibyte international characters sets and print the ESC character as a single character
instead of “^[” for the current Telnet session:
Command
Purpose
terminal international
Configure a router to display 8-bit and multibyte international character sets and
print the ESC character as a single character instead of “^[” when Telneting to a
Cisco IOS platform for the current session.
Using the Cisco Web Browser FC-115
Configure the Web Cache Control Protocol
Configure the Web Cache Control Protocol
The Web Cache Control Protocol (WCCP) feature allows you to use a Cisco Cache Engine to handle
Web traffic, thus reducing transmission costs and downloading time. This traffic includes user
requests to view pages and graphics on World Wide Web servers, whether internal or external to your
network, and the replies to those requests. Figure 10 shows a sample WCCP network configuration.

Router
Clients
Cache 1

Clients
S6529
Cache 3
When a user (client) requests a page from a Web server (located in the Internet, in this case), the
router sends the request to a Cisco Cache Engine (Cache 1, Cache 2, or Cache 3). If the cache engine
has a copy of the requested page in storage, the engine sends the user that page. Otherwise, the
engine gets the requested page and the objects on that page from the Web server, stores a copy of the
page and its objects (caches them), and forwards the page and objects to the user.
WCCP transparently redirects HTTP requests from the intended server to a Cisco Cache Engine.
End users do not know that the page came from the cache engine rather than the originally requested
Web server.
The Using Cisco Cache Engine publication contains detailed information about the Cisco Cache
Engine and discusses alternative network configurations.
Benefits of Using WCCP
Web caches reduce transmissions costs and the amount of time required to download Web files. If a
client requests a Web page that is already cached, the request and data only have to travel between
the Cisco Cache Engine and the client. Without a Web cache, the request and reply must travel over
the Internet or wide-area network. Cached pages can be loaded faster than non-cached pages and do
not have to be transmitted from the Internet to your network.
Cisco IOS support of WCCP provides a transparent Web cache solution. Users can benefit from Web
proxy caches without having to configure clients to contact a specific proxy server in order to access
Web resources. Many Web proxy caches require clients to access Web resources through a specific
proxy Web server rather than using the originally requested Web server URL. With WCCP, the
clients send Web requests to the desired Web server URL. Cisco IOS routers intelligently intercept
HTTP requests and transparently redirect them to a Cisco Cache Engine.
FC-116
Configuration Fundamentals Configuration Guide
Platforms Supported
When a Web Cache Control Protocol-enabled router receives an IP packet, the router determines if
the packet is a request that should be directed to a Cisco Cache Engine. The router looks for TCP as
the protocol field in the IP header and for 80 as the destination port in the TCP header. If the packet
meets these criteria, it is redirected to a Cisco Cache Engine.
Through communication with the Cisco Cache Engines, the routers running WCCP are aware of
available cache engines.

fast switching path on the interface.
6
end
Exit configuration mode.
7
copy running-config startup-config

Step
Command
Purpose
1
show ip wccp
Display global Web Cache Control Protocol statistics.
2
show ip wccp web-caches
Display information about all known Cisco Cache Engines.
3
show ip interface
Show whether Web cache redirecting is enabled on an
interface.
The show ip wccp and show ip wccp web-caches commands display a count of the number of
packets redirected. Use the clear ip wccp EXEC command to clear this counter.
What to Do Next
To use WCCP, the Cisco Cache Engine must be properly configured. Refer to the Using the Cisco
Cache Engine publication for details on configuring the Cisco Cache Engine. Keep these important
points in mind:
FC-118
•
•
•
The IP address of the router must be configured as the home router for the Cisco Cache Engine.
•
Placing a Cisco Cache Engine beyond a Web-cache-redirect enabled interface and along the route
to the server will not cause the IP route cache to be populated with an entry.
Versions of software on the Cisco Cache Engines must be compatible with the router.
The Cisco Cache Engines must not have their packets encrypted or compressed and should be
part of the “inside” Network Address Translation if one is present.

WCCP Configuration Example
The following example configures a router to support the Web Cache Control Protocol and to
redirect Web-related packets from Ethernet interface 0 to the Cisco Cache Engine:
Router# configure terminal
Router(config)# ip wccp enable
Router(config)# interface Ethernet 0
Router(config-if)# ip web-cache redirect
Router(config-if)# end
Router#
%SYS-5-CONFIG_I: Configured from console by console.
Router# copy running-config startup-config
After the router has been configured, use the show ip wccp web-cache command to verify that Web
Cache Control Protocol is enabled and aware of Cisco Cache Engines. In this example, the show ip
wccp web-cache command is entered immediately after the router has been configured. After a few
seconds, the cache engine becomes usable, as seen in the second output.
