Cisco Cisco Digital Media Player 4300G Guida All'Installazione

When a DMP 4310G relies upon a Medianet switch where more than one VLAN uses DHCP, the DMP 
might come to use the wrong IP address. For this to occur, temporary conditions that do not sever the 
DMP’s AC power connection must nonetheless interrupt its network connection through the switch. 
(Thus, this problem cannot possibly occur while the DMP uses PoE.) Specifically, the Medianet switch 
assigns its default VLAN to your DMP. But then — after your DMP’s network connection is interrupted 
and restored — your Medianet switch assigns to your DMP a dynamic IP address from another VLAN 
on your Medianet switch. This easily prevented mismatch disrupts centralized management of your 
DMP. To prevent this problem or to recover from it, you can download and run the patch from Cisco.com.

The factory-default behavior for every DMP is to obtain and use a dynamic IP address from a DHCP 
server in its local network segment. 

Nonetheless, your DMP must have an IP address — even when you will deploy it where the local network 
segment does not include any DHCP server among its nodes. In this case, you must configure your DMP 
before you deploy it. This technique is sometimes called a green field deployment. The configuration 
steps differ in Ethernet and wireless networks.

Does a security policy in your network restrict DHCP address assignments to known MAC 
addresses? If so, locate the MAC address printed on a sticker that is affixed to your DMP. Then, 
share this address with your security policy administrator. 

Does your DMP support wireless networking? If so, consider whether you might prefer to use that 
method instead of this one.
