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 sup-
porting 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.
Command Mode Description
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 ]
Bridge
Deletes 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.
8.1.3 MAC-based VLAN
The switch can assign a frame to a VLAN based on the source MAC address in the re-
ceived frames. Using this, all frames emitted by a given end station will be assigned to
the same VLAN, regardless of the port on which the frame arrives. This is useful for mo-
bility application.
To configure a MAC-based VLAN, follow these steps.
1. Create VLAN groups for the MAC addresses you want to use.
2. Map the MAC address to the appropriate VLAN.
Command Mode Description
vlan macbase MAC-ADDR
VLANS
Adds a specified MAC address to a MAC-based VLAN.
MAC-ADDR: MAC address of end station
VLANS: VLAN ID (1-4094)
no vlan macbase MAC-ADDR
Bridge
Deletes a specified MAC address from a specified
MAC address
