Designation

Description

SRST 

Indicates a Survivable Remote Site Telephony router that can provide Cisco Unified Communications Manager functionality with a limited feature set. This router assumes control of call processing if all other Cisco Unified Communications Manager servers become unreachable. The SRST Cisco Unified Communications Manager always appears last in the list of servers, even if it is active.  

For more information, see the “Survivable Remote Site Telephony Configuration” chapter in the Cisco Unified Communications Manager Administration Guide.

TFTP

 
Indicates that the phone was unable to register with a Cisco Unified Communications Manager listed in its configuration file, and it registered with the TFTP server instead.
               

Appears as a shield and indicates that the call is from a trusted device,  and that the connection to Cisco Unified Communications Manager is  authenticated. For more information about authentication, see the Cisco Unified Communications Manager Security Guide.

(Encryption icon)

Appears as a padlock and indicates that the call is from a trusted device,  and that the connection to Cisco Unified Communications Manager is  authenticated and encrypted. For more information about authentication  and encryption, see the Cisco Unified Communications Manager Security Guide.   

The Encryption icon is also displayed when a Cisco Unified IP Phone  is configured as protected. For more information about protected calls,  see the Cisco Unified Communications Manager Security Guide.  Protected calls are not authenticated.

Load Server

Used to optimize installation time for phone firmware upgrades and offload the WAN by storing images locally, negating the need to traverse the WAN link for each phone's upgrade.

You can set the Load Server to another TFTP server IP address or name other than the TFTP Server 1 or TFTP Server 2 from which the phone firmware can be retrieved for phone upgrades. When the Load Server option is set, the phone contacts the designated server for the firmware upgrade.

Note

The Load Server option allows you to specify an alternate TFTP server for phone upgrades only. The phone continues to use TFTP Server 1 or TFTP Server 2 to obtain configuration files. The Load Server option does not provide management of the process and of the files, such as file transfer, compression, or deletion. 

From Cisco Unified Communications Manager Administration, choose Device > Phone > Phone Configuration.

Enable CDP on the PC port when Cisco VT Advantage/Unified Video Advantage (CVTA) is connected to the PC port. CVTA does not work without CDP interaction with the phone.

Note 

When CDP is disabled in Cisco Unified Communications Manager, a warning is presented when CDP is disabled on the PC port prevents CVTA from working.

Note 

The current PC and switch port CDP values are shown on the Settings menu.

From Cisco Unified Communications Manager Administration, choose Device > Phone.

CDP: SW Port

Indicates whether CDP is supported on the switch port (default is enabled).

• Enable CDP on the switch port for VLAN assignment for the phone, power negotiation, QoS management, and 802.1x security.
  
  
• Enable CDP on the switch port when the phone is connected to a Cisco switch.

Note    

When CDP is disabled in Cisco

Unified Communications Manager,a warning is presented when CDP is disabled on the switch port only if the phone is connected to a non-Cisco switch.

Note  

The current PC and switch port CDP values are shown on the Settings menu.

From Cisco Unified Communications Manager Administration, choose Device > Phone.

Peer Firmware Sharing

The Peer Firmware Sharing feature provides these advantages in high speed campus LAN settings:

• Limits congestion on TFTP transfers to centralized remote TFTP servers
  
  
• Eliminates the need to manually control firmware upgrades
  
  
• Reduces phone downtime during upgrades when large numbers of devices are reset simultaneously

Peer Firmware Sharing may also aid in

firmware upgrades in branch/remote office deployment scenarios over bandwidth-limited WAN links.

When enabled, it allows the phone to discover similar phones on the subnet that are requesting the files that make up the firmware image, and to automatically assemble transfer hierarchies on a per-file basis. The individual files making up the firmware image are retrieved from the TFTP server by only the root phone in the hierarchy, and are then rapidly transferred down the transfer hierarchy to the other phones on the subnet using TCP connections.

This menu option indicates whether the phone supports peer firmware sharing.

Settings include:

• Enabled—default
  
• Disabled
  

From Cisco Unified Communications Manager

Administration, choose Device >

Phone > Phone Configuration.

Log Server

Indicates the IP address and port of the remote logging machine to which the phone sends log messages. These log messages help in debugging the Peer Firmware Sharing feature.

• IPv6—The dual-stack phone prefers to establish a connection via an IPv6 address during a signaling event

Default: Use System Default

From Cisco Unified Communications Manager

Administration, choose Device >

Auto IP Configuration

Displays whether the auto configurations is enabled or disabled on the phone.

The Auto IP Configuration setting along with the DHCPv6 setting determine how the IP Phone obtains its IPv6 address and other network settings. For more information on how these two settings affect the network settings on the phone, see DHCPv6 and Autoconfiguration.

Note

Use the “Allow Auto-Configuration for Phones”

IPv6 Load Server

Used to optimize installation time for phone firmware upgrades and off load the WAN by storing images locally, negating the need to traverse the WAN link for each phone's upgrade.

You can set the Load Server to another TFTP server IP address or name other than the IPv6 TFTP Server 1 or IPv6 TFTP Server 2 from which the phone firmware can be retrieved for phone upgrades. When the Load Server option is set, the phone contacts the designated server for the firmware upgrade.

Note

The Load Server option allows you to specify an alternate TFTP server for phone upgrades only. The phone continues to use IPv6 TFTP Server 1 or IPv6 TFTP Server 2 to obtain configuration files. The Load Server option does not provide management of the process and of the files, such as file transfer, compression, or deletion.
