Chapter 11 Register DMPs

Reference

Prevent DHCP Address Assignments to the Wrong VLAN

		Note	You can run the following shell script (“mandatory.cdp.sh”) on a Cisco Catalyst 3750 Series switch. This shell script can
			prevent a type of DHCP-VLAN misalignment problem that we describe under the “Medianet” heading in the
			“Restrictions” section on page 11-9.
		Tip		To learn about shell script execution on your switch, see the documentation for your switch on Cisco.com.
