I am aware of the following types of Vlan's.
Default VLAN: This is basically where ALL ports belongs to by default, this is technically VLAN 1 and it can't be deleted from the switch. Data VLAN: Native VLAN: The native VLAN is an 802.1Q only concept. Voice VLAN: The voice VLAN is where the QoS policies are applied in order to prioritize this traffic to send it through the LAN. Management VLAN: This is used on a LAN for management purporses. Special VLANs: These VLANs are basically used for special cases on your LAN. Reserved VLANs: There are some VLANs that are reserved internally on your switch in order to use them on other enviroments like FDDI, Token Ring. Private VLANs it's a technology that has some new concpets/category of VLANs.
But recently in a dell powerconnect switch i saw Vlan type as permanent. Can anybody please tell me what a permanent vlan type would mean.
