Building a Device Linker Web Page
A device linker web page:
Simplifies access to the many device-management interfaces in the network.
Provides links to the telnet, console, and HTTP ports of Cisco IOS devices.
Figure 19 Device Linker Used to Access Devices
By using a Cisco terminal server for out-of-band console access, such as a Cisco 2511, the consoles are
available at TCP port 20
xx
on a terminal server. The target line number replaces
xx
. For example to get
to line 1, telnet to port 2001. The equivalent URL is telnet://172.21.101.250:2001
To build a device linker web page, follow these steps:
Step 1
Collect the IP addresses for the Cisco IOS devices.
Step 2
Collect the device console out-of-band (OOB) paths for the terminal server and the lines connected to
Cisco IOS devices.
Step 3
Create a basic HTML table and enter the information for each device. The telnet and HTTP information
is in bold in the following HTML code fragment. Step 4 shows what the table looks like in a web
browser.
