Chapter 42 Cisco IP Phone Configuration
Configuring Cisco IP Phones
Displaying the MAC Address of a Phone
The Media Access Control (MAC) address comprises a unique, 12-character,
hexadecimal number that identifies a Cisco IP phone or other hardware device.
Locate the number on a label on the bottom of the phone (for example,
000B6A409C405 for Cisco IP Phone 7900 Family models or
SS-00-0B-64-09-C4-05 for Cisco IP Phone models SP 12+ and 30 VIP).
Cisco CallManager makes the MAC address a required field for Cisco IP phone
device configuration. When entering the MAC address in Cisco CallManager
fields, do not use spaces or dashes and do not include the "SS" that may precede
the MAC address on the label.
To display the MAC address when the phone is powered on, perform the following
steps:
• Cisco IP Phone 7960 and 7940 models—Press Settings, use the arrow buttons
to highlight the Network Configuration menu option, and press the Select
softkey.
• Cisco IP Phone 7910 — Press Settings, use the arrow buttons to locate
Network Config options, and press 6 on the phone keypad to begin displaying
the Network Config options; then, use the arrow keys to scroll the Network
Config option display to the MAC address.
• Cisco IP Phone models 12 SP+ and 30VIP—Press ** to display the MAC
address on the second line of the LCD display.
For more information about displaying additional configuration settings on
Cisco IP phones, refer to the Cisco IP Phone 7900 Family Administration Guide
and the individual Getting Started publications provided with Cisco IP phones.
