Two vlans, One Port, No trunk

I recall a task somewhere I don't remember where we needed two vlans on one port but no trunk...in this case you can use a voice vlan for your second vlan. It is very easy to test:

Topology:

R1---SW1---SW2---R2

R1's interface:

interface Ethernet0/0

interface Ethernet0/0.2
encapsulation dot1Q 2
ip address 139.1.2.101 255.255.255.0

SW1:

interface FastEthernet0/1
switchport access vlan 11
switchport voice vlan 2

SW2:

SW2#show cdp ne | in R2
R2 Fas 0/2 135 R S I 3640 Eth 0/0
SW2#

Rack1SW2#show run int f0/2
Building configuration...

Current configuration : 83 bytes
!
interface FastEthernet0/2
switchport access vlan 2
switchport mode access

So let's ping from R1 to R2 (139.1.2.2)

Rack1R1#ping 139.1.2.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 139.1.2.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/4/4 ms
