Chapter 12 Configuring VLANs
Configuring VMPS
Beginning in privileged EXEC mode, follow these steps to configure a dynamic access port on a VMPS
client switch:
To return an interface to its default configuration, use the default interface interface-id interface
configuration command. To return an interface to its default switchport mode (dynamic desirable), use
the no switchport mode interface configuration command. To reset the access mode to the default
VLAN for the switch, use the no switchport access interface configuration command.
Note When you configure a dynamic access port by using the switchport access vlan dynamic interface
configuration command, the port might allow unauthorized users to access network resources if the
interface changes from access mode to trunk mode through the DTP negotiation. The workaround is to
configure the port as a static access port.
Reconfirming VLAN Memberships
Beginning in privileged EXEC mode, follow these steps to confirm the dynamic port VLAN membership
assignments that the switch has received from the VMPS:
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 interface interface-id Enter interface configuration mode and the switch port that is
connected to the end station.
Step 3 switchport mode access Set the port to access mode.
Step 4 switchport access vlan dynamic Configure the port as eligible for dynamic VLAN membership.
The dynamic access port must be connected to an end station.
Step 5 end Return to privileged EXEC mode.
Step 6 show interfaces interface-id switchport Verify your entries in the Operational Mode field of the display.
Step 7 copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Step 1 vmps reconfirm Reconfirm dynamic port VLAN membership.
Step 2 show vmps Verify the dynamic VLAN reconfirmation status.
