Separate VLANs typically imply separate IP networks. Be sure to plan the new IP
addressing scheme and its deployment to stations before moving users to the new VLAN.
Separate VLANs also require inter-VLAN routing to permit users in the new VLAN to
communicate with other VLANs. Inter-VLAN routing includes setting up the appropriate
IP parameters and services, including default gateway and DHCP.
Changing VLANs and Port Membership
To modify VLAN attributes, such as VLAN name, use the vlan vlan-id global con?¬?guration
command.
To move a port into a different VLAN, use the same commands that you used to make the
original assignments.
You do not need to ?¬?rst remove a port from a VLAN to make this change. After you reassign
a port to a new VLAN, that port is automatically removed from its previous VLAN.
Deleting VLANs and Port Membership
When you delete a VLAN from a switch that is in VTP server mode, the VLAN is removed
from all switches in the VTP domain. When you delete a VLAN from a switch that is in
VTP transparent mode, the VLAN is deleted only on that speci?¬?c switch. Use the global
con?¬?guration command no vlan vlan-id to remove a VLAN.
