Chapter12 Configuring VLANs
Configuring VMPS
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 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 th e VMPS.You
can set the number of minutes after which reconfirmation occ urs.
If you are configuring a member switch in a cluster, this 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.
Beginning in privileged EXEC mode, follow these steps to change the reconfirmation interval:
To return the switch to its default setting, use the no vmps reconfirm global configuration command.
Step4 switchport access vlan dynamic Configure the port as eligible for dynamic VLAN membership.
The dynamic-access port must be connected to an end station.
Step5 end Return to privileged EXEC mode.
Step6 show interfaces interface-id switchport Verify your entries in the Operational Mode field of the display.
