8.1.1.4 Deleting VLAN
To delete VLAN, use the following command.
Deletes VLAN, enter the VLAN ID to be deleted.
When you delete a VLAN, all ports must be removed from the VLAN; the VLAN must be
empty.
8.1.2 Protocol-based VLAN
User can use a VLAN mapping that associates a set of processes within stations to a
VLAN rather than the stations themselves. Consider a network comprising devices
supporting multiple protocol suites. Each device may have an IP protocol stack, an
AppleTalk protocol stack, an IPX protocol stack and so on.
If we configure VLAN-aware switches such that they can associate a frame with a VLAN
based on a combination of the station’s MAC source address and the protocol stack in
use, we can create separate VLANs for each set of protocol-specific applications.
To configure a protocol-based VLAN, follow these steps.
1. Configure VLAN groups for the protocols you want to use.
2. Create a protocol group for each of the protocols you want to assign to a VLAN.
3. Then map the protocol for each interface to the appropriate VLAN.
vlan pvid PORTS ethertype
ETHERTYPE VLANS
Adds a port with a protocol-based VLAN.
PORTS: port number
ETHERTYPE: Ethernet type (e.g. 0x800)
VLANS: VLAN ID (1-4094)
no vlan pvid PORTS ethertype
[ETHERTYPE]
Removes a port from a protocol-based VLAN.
Because Protocol Based VLAN and normal VLAN run at the same time, Protocol Based
VLAN operates only matched situation comparing below two cases.
1. When Untagged Frame comes in and matches with Protocol VLAN Table, tags PVID
which configured on Protocol VLAN. But in no matched situation, tags PVID which
configured on and operates VLAN.
2. When Tagged Frame comes in and VID is 0, it switches by Protocol VLAN Table. But
if VID is not 0, it switches by normal VLAN Table.
