For the cluster-based port-naming conventions, see the "VMPS Database Configuration File" section on page 8-37. • When you configure a port as dynamic, the spanning-tree Port Fast feature is automatically enabled for that port. The Port Fast mode accelerates the process of bringing the port into the forwarding state. You can disable Port Fast mode on a dynamic port. • Secure ports cannot be dynamic ports. You must disable port security on the port before it becomes dynamic. • Trunk ports cannot be dynamic ports, but it is possible to enter the switchport access vlan dynamic interface configuration command for a trunk port. In this case, the switch retains the setting and applies it if the port is later configured as an access port. You must turn off trunking on the port before the dynamic access setting takes effect. • Dynamic ports cannot be network ports or monitor ports. • The VTP management domain of the VMPS client and the VMPS server must be the same. 8-38 Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide 78-6511-08
