Configuring Dynamic Access Ports on VMPS Clients

If you are configuring a port on a cluster member switch as a dynamic port, first use the rcommand
privileged EXEC command to log into the member switch.
Caution Dynamic port VLAN membership is for end stations or hubs connected to end stations. Connecting
dynamic access ports to other switches can cause a loss of connectivity.
Beginning in privileged EXEC mode, follow these steps to configure a dynamic access port on a VMPS
client switch:
Command
Step 1 configure terminal
Step 2
interface interface-id
Step 3
switchport mode access
Step 4 switchport access vlan dynamic
Step 5 end
Step 6
show interfaces interface-id switchport
Step 7 copy running-config startup-config
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.
When you configure a dynamic access port by using the switchport access vlan dynamic interface
Note
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
Step 1 vmps reconfirm
Step 2 show vmps

Purpose
Enter global configuration mode.
Enter interface configuration mode and the switch port that is
connected to the end station.
Set the port to access mode.
Configure the port as eligible for dynamic VLAN membership.
The dynamic access port must be connected to an end station.
Return to privileged EXEC mode.
Verify your entries in the Operational Mode field of the display.
(Optional) Save your entries in the configuration file.
Purpose
Reconfirm dynamic port VLAN membership.
Verify the dynamic VLAN reconfirmation status.
