Chapter 15 Configuring VLANs
Configuring VMPS
Caution Dynamic-access 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:
To return an interface to its default configuration, use the default i
nterface interface-id interface
configuration command. To return an interface to its default switchport mode (dynamic auto), 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 vlan interface configuration command.
Reconfirming VLAN Memberships
Beginning in privileged EXEC mode, follow these steps to confirm the dynamic-access port VLAN
membership assignments that the switch has received from the VMPS:
Changing the Reconfirmation Interval
VMPS clients periodically reconfirm the VLAN membership information received from the VMPS.You
can set the number of minutes after which reconfirmation occurs.
If you are configuring a member switch in a cluster, thi
s parameter must be equal to or greater than the
reconfirmation setting on the command switch. You must also first use the rcommand privileged EXEC
command to log in to the member switch.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Specify the switch port that is connected to the end station, and enter
interface configuration mode.
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 s
tation.
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-access port VLAN membership.
Step 2
show vmps Verify the dynamic VLAN reconfirmation status.
