Monitoring the Cisco Unified IP Phone Remotely
Each Cisco Unified IP Phone has a web page from which you can view a variety of information about the phone, including:
•
Device information
•Network configuration information
•Network statistics
•Device logs
•Streaming statistics
This chapter describes the information that you can obtain from the phone's web page. You can use this information to remotely monitor the operation of a phone and to assist with troubleshooting.
You can also obtain much of this information directly from a phone. For more information, see "Viewing Model Information, Status, and Statistics on the Cisco Unified IP Phone."
For more information about troubleshooting the Cisco Unified IP Phone 7970 Series, see Chapter 9, "Troubleshooting and Maintenance."
This chapter includes these topics:
•Accessing the Web Page for a Phone
•Disabling and Enabling Web Page Access
•Device Information
•Network Configuration
•Network Statistics
•Device Logs
•Streaming Statistics
Accessing the Web Page for a Phone
To access the web page for a Cisco Unified IP Phone, perform these steps.
Note If you cannot access the web page, it may be disabled. See the "Disabling and Enabling Web Page Access" section for more information.
Procedure
Step 1 Obtain the IP address of the Cisco Unified IP Phone using one of these methods:
•Search for the phone in Cisco Unified CallManager by choosing Device > Phone. Phones registered with Cisco Unified CallManager display the IP address at the top of the Phone Configuration web page.
•On the phone, press the Settings button, choose Network Configuration, and 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 Cisco Unified IP Phone:
http://IP_address
The web page for a Cisco Unified IP Phone 7970 Series includes these hyperlinks:
•Device Information—Displays device settings and related information for the phone. For more information, see the "Device Information" section.
•Network Configuration—Displays network configuration information and information about other phone settings. For more information, see the "Network Configuration" section.
•Network Statistics—Includes the following hyperlinks, which provide information about network traffic:
–Ethernet Information—Displays information about Ethernet traffic. For more information, see the "Network Statistics" section.
–Access—Displays information about network traffic to and from the PC port on the phone. For more information, see the "Network Statistics" section.
–Network—Displays information about network traffic to and from the network port on the phone. For more information, see the "Network Statistics" section.
•Device Logs—Includes the following hyperlinks, which provide information that you can use for troubleshooting:
–Console Logs—Includes hyperlinks to individual log files. For more information, see the "Device Logs" section.
–Core Dumps—Includes hyperlinks to individual dump files.
–Status Messages—Displays up to the 10 most recent status messages that the phone has generated since it was last powered up. For more information, see the "Device Logs" section.
–Debug Display—Displays messages that might be useful to the Cisco TAC if you require assistance with troubleshooting. For more information, see the "Device Logs" section.
•Streaming Statistics—Includes the Stream 1, Stream 2, and Stream 3 hyperlinks, which display a variety of streaming statistics. For more information, see the "Streaming Statistics" section.
Disabling and Enabling Web Page Access
For security purposes, you may choose to prevent access to the web pages for a phone. If you do so, you will prevent access to the web pages that are described in this chapter and to the phone's User Options web pages.
To disable access to the web pages for a phone, follow these steps from Cisco Unified CallManager Administration:
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 window for the device.
Step 4 From the Web Access drop-down list box, choose Disabled.
Step 5 Click Update.
Note Some features, such as Cisco Quality Report Tool, do not function properly without access to the phone web pages. Disabling web access also affects any serviceability application that relies on web access, such as CiscoWorks.
To enable web page access when it is disabled, see the preceding steps about disabling access. Follow the same steps, but choose Enabled in Step 4 to enable the web page.
