Assigning a Subnet Mask
The subnet mask is used to partition the IP address into a network and a host
identifier. The subnet mask is used to mask a portion of the IP address so that
TCP/IP can distinguish the network ID from the host ID.
Before you can assign a subnet mask, you must disable DHCP. For instructions,
see the “Disabling DHCP” section on page 4-15.
To assign a subnet mask for the Cisco Unified IP Phone, follow these steps:
Using the Phone Configuration Web Page
Procedure
Step 1 Display the Phone Configuration web page.
For instructions, see the “Accessing Network Settings through a Phone
Configuration Web Page” section on page 4-2.
Step 2 In the pane on the left under Change Configuration, click Network Parameters.
You may be prompted to enter a password.
The Network Parameters web page appears.
Step 3 To set the subnet mask, enter an address in the StaticNetMask field and click
Apply.
