Chapter11 Register DMPs

Concepts

Digital Signs

a. Create and save a system task that uses:

•Set as its request type.

•init.startService_msi=yes&mib.save=1&mng.reboot=1 as its request string.

b. Schedule and deploy the system task to run on your DMP 4310G or 4400G.

The request string includes a command to restart your DMP.

Restrictions

Non-Medianet Autoregistration

•DMM-native autoregistration—which does not use any Medianet technologies— depends upon the

Cisco TAC Troubleshooting Access option for DMPs and fails unless this option is enabled.

DHCP

•As of May 2011, these DHCP servers have passed our tests for using Medianet with DMPs.

Note This CiscoDMS release does not support any DHCP server that runs on any Cisco router or switch.

•All DMPs that you manage centrally in DMM must share one identical set of DMPDM

Medianet

•A DMP 4310G might come to use the wrong IP address when it relies upon a Medianet switch where

more than one VLAN uses DHCP. For the switch to bungle IPaddress assignment in this way,

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 this same switch. The mismatch

disrupts centralized management of your DMP.

To prevent this problem or to recover from it, you must run a shell script on your switch. See the

“Prevent DHCP Address Assignments to the Wrong VLAN” section on page11-21.
