Cisco Cisco TelePresence MX700 Manual De Mantenimiento

between the switch and the endpoint, resulting in a large 

percentage of loss on that interface. CDP does not automate 

the resolution of such a condition, but it does detect it and 

cause an alarm to be generated on the switch, notifying the 

administrator of the condition so that he or she may take steps 

to resolve it.

Future Medianet applications
The above benefits of CDP have been available for years from 

Cisco. Medianet is a new concept aimed at further extending 

and automating the interactions between endpoints and the 

network in order to deliver additional end-to-end optimization 

of multimedia traffic across an intelligent internetwork. CDP is 

one protocol, among others, that will be leveraged by future 

generations of Cisco IOS Software and Cisco Medianet-

ready endpoints to deliver on this vision. Available Medianet 

applications at the time this document was written include 

end-to-end tracing of the path a video session takes through 

a network in order to pinpoint the source of packet loss, 

optimizing the routing of video packets over alternate paths in 

order to maximize the throughput of the network, enhanced 

Session Admission Control in order to control the amount of 

video sessions admitted onto the network, and more.

CDP behavior in release TC5, and later
The following information applies to Cisco TelePresence MX 

series, EX series, Codec C Series, Profile series and Quick 

Set C20 running software release TC5.0, and later; and 

Cisco TelePresence SX20 Quick Set which is supported from 

release TC5.1, and later; and EX Series supported in TE6.0. 

When the endpoint is booted for the first time, or after a 

factory reset has been done, the following settings are 

applied by default:

xConfiguration Provisioning Mode: Auto
xConfiguration Network 1 VLAN Voice Mode: Off

The endpoint then displays the Provisioning Wizard screen to 

prompt the user for what provisioning mode they would like to 

use: VCS, Callway or CUCM. 

If CUCM is selected, then xConfiguration Provisioning Mode 

is automatically set to CUCM and xConfiguration Network 

1 VLAN Voice Mode is automatically changed to Auto. Also 

the endpoint begins utilizing CDP to automatically discover 

its VLAN and begins tagging its packets with the appropriate 

VLAN ID. The endpoint also begins including DHCP Option 

150 in its DHCP requests so that it can automatically discover 

the address of the Cisco Unified CM TFTP server.

If the xConfiguration Provisioning Mode is set to VCS or 

Callway, then xConfiguration Network 1 VLAN Voice Mode is 

left in its default state of Off, and the endpoint will ignore any 

CDP VLAN advertisements and not tag its packets with any 

VLAN ID. The endpoint also does not include DHCP Option 

150 in its DHCP requests.

For TMS/VCS customers, this behavior preserves the 

functionality they had in previous software releases of these 

endpoints. If CDP is desired, then it may be manually enabled 

by setting the xConfiguration Network 1 VLAN Voice Mode 

parameter to Auto. 

This may be done through: 

•  Touch user interface: Administrator Settings -> Network 

Settings -> Link Settings. 

•  Or the On-Screen Display Menu: Settings -> Administrator 

•  Or the web interface: Configuration -> Advanced 

•  Or the API command: 

xConfiguration Network 1 

VLAN Voice Mode.

For CUCM customers, this behavior does present an extra 

step in the first-time boot up process, but once CUCM mode 

has been chosen in the Startup Wizard, CDP will automatically 

kick in and the phone will join the auxiliary (voice/video) VLAN. 

If the customer does not wish to use the CDP, then it may be 

manually disabled by setting the xConfiguration Network 1 

VLAN Voice Mode parameter to Off.

For customers who do not have a CDP-capable Ethernet 

switch, but wish to use 802.1Q VLANs, the xConfiguration 

Network 1 VLAN Voice Mode parameter may be set to 

Manual, and the associated xConfiguration Network 1 VLAN 

Voice ID parameter may be set to the appropriate value.

Once these parameters are set, the settings are saved and 

remain persistent through subsequent reboots. If a user later 

wishes to change them, they may do so by re-running the 

Startup Wizard, or by manually setting the parameters.
