Cisco Systems OL-14587-01 Manual De Usuario

For information about configuring Cisco Unified Communications Manager to 
work with the IP devices that described in this chapter, refer to Cisco 
Unified Communications Manager Administration Guide, Cisco Unified 
Communications Manager System Guide, and to Cisco Unified Communications 
Manager Security Guide.

For an overview of security functionality for the Cisco Unified IP Phone, see the 

.

If the Cisco Unified IP Phone model that you want to configure does not appear 
in the Phone Type drop-down list in Cisco Unified Communications Manager 
Administration, go to the following URL and install the latest support patch for 
your version of Cisco Unified Communications Manager: 

The Cisco Unified IP Phone 7931G has an internal Ethernet switch, enabling 
forwarding of packets to the phone, and to the access port and the network port on 
the back of the phone.

If a computer is connected to the access port, the computer and the phone share 
the same physical link to the switch and share the same port on the switch. This 
shared physical link has the following implications for the VLAN configuration 
on the network:

The current VLANs might be configured on an IP subnet basis. However, 
additional IP address might not be available to assign the phone to the same 
subnet as other devices connect to the same port.

Data traffic present on the data/native VLAN may reduce the quality of 
Voice-over-IP traffic.

Network security may indicate a need to isolate the VLAN voice traffic from 
the VLAN data traffic.
