Check TFTP Settings

Procedure

Step 1 You can determine the IP address of the TFTP server used by the phone by pressing Settings, choosing

Network Configuration > IPv4 and scrolling to the TFTP Server 1 option.

Step 2 If you have assigned a static IP address to the phone, you must manually enter a setting for the TFTP Server

1 option. See Network Configuration Menu.

Step 3 If you are using DHCP, the phone obtains the address for the TFTP server from the DHCP server. Check the

IP address configured in Option 150.

Step 4 You can also enable the phone to use an alternate TFTP server. Such a setting is particularly useful if the

phone was recently moved from one location to another. See Network Configuration Menu for instructions.

Check DHCP Settings

Procedure

Step 1 On the Cisco Unified IP Phone, choose Settings > Network Configuration > IPv4 Configuration, and look

at the following options:

• DHCP Server: If you have assigned a static IP address to the phone, you do not need to enter a value for

the DHCP Server option. However, if you are using a DHCP server, this option must have a value. If it

does not, check your IP routing and VLAN configuration. See the Troubleshooting Switch Port and

Interface Problems document, available at this URL :

http://www.cisco.com/en/US/products/hw/switches/ps708/prod_tech_notes_list.html

• IP Address, Subnet Mask, Default Router: If you have assigned a static IP address to the phone, you

must manually enter settings for these options. See Network Configuration Menu for instructions.

Step 2 If you are using DHCP, check the IP addresses distributed by your DHCP server. See the Understanding and

Troubleshooting DHCP in Catalyst Switch or Enterprise Networks document, available at this URL:
