Remote Monitoring Overview

Each Cisco Unified IP Conference Phone has a web page from which you can view a variety of information about the conference phone, including:

Device information
Network configuration information
Ethernet information
Device logs
Streaming statistics

This chapter describes the information that you can obtain from the conference phone web page. You can use this information to remotely monitor the operation of a conference phone and to assist with troubleshooting.

You can also obtain much of this information directly from a conference phone. For more information, see Model Information, Status, and Statistics.

For more information about troubleshooting the conference phone, see Troubleshooting and Maintenance.

Access Web Page

Note

If you cannot access the web page, it may be disabled. See the Control Web Page Access section for more information.

Procedure

Step 1

Obtain the IP address of the conference phone using one of these methods:

From Cisco Unified Communications Manager Administration, choose Device > Phone. Enter search criteria to locate the conference phone, and then click the conference phone name. Conference phones registered with Cisco Unified Communications Manager display the IP address at the top of the Phone Configuration web page.
On the conference phone, choose Apps > Settings > Network Configuration. Then, scroll to the IP Address option.

Step 2

Open a web browser and enter the following URL, where IP address is the IP address of the conference phone: http://<IP_address>

Web Page Information

The web page for a conference phone includes these hyperlinks:

Device Information: Displays device settings and related information for the conference phone.
Network Configuration: Displays network configuration information and information about other conference phone settings.
Ethernet Information: Displays network statistics.
Device Logging: Displays messages that might be useful to Cisco TAC if you require assistance with troubleshooting.
Streaming Statistics: Displays call statistics.

Control Web Page Access

For security purposes, you may choose to prevent access to the web pages for a conference phone. If you do so, you will prevent access to the web pages that are described in this chapter and to the Cisco Unified Communications Manager Self Care Portal.

To enable or disable access to the web pages for a conference phone, follow these steps from Cisco Unified Communications Manager Administration:

Procedure

Step 1

Choose Device > Phone.

Step 2

Specify the criteria to find the phone and click Find, or click Find to display a list of all phones.

Step 3

Click the device name to open the Phone Configuration web page for the device.

Step 4

In the Product Specific Configuration Layout area, from the Web Access drop-down list, choose Enabled or Disabled.

Step 5

Click Update.

Note

Some features, such as Cisco Quality Report Tool, do not function properly without access to the conference phone web pages. Disabling web access also affects any serviceability application that relies on web access, such as CiscoWorks.
