How to access multiple VLANs from one pc?

[Joris Syen]

Good day,

I have a quick question, this is the situation:

- 1x layer2 switch that has these VLANs specified:

VLAN11: Manufacturing 192.168.1.x 255.255.255.0

VLAN12: Management 192.168.2.x 255.255.255.0

-1x desktop pc with 1 ehternet card

Is it in any way possible to have the desktop pc connected to the switch and have it communicate with both VLANs?

I thought it wasn't possible but I may be wrong because I am not that experienced yet.

Thanks in advance,

Best Regards,

Joris

HI Joris,

May be I understand your question correctly.

You can access any vlan...from 1 pc.

All these routing done by layer 3 switchor a router.

If you are using layer 3 switch then you can use this config :

Switch configuration

ip routing
!
interface FastEthernet0/1
switchport access vlan 10
switchport mode access
!
interface FastEthernet0/2
switchport access vlan 20
switchport mode access

interface Vlan10
ip address 192.168.10.1 255.255.255.0
!
interface Vlan20
ip address 192.168.20.1 255.255.255.0

And on hosts just assign IP addresses and default gateways (to the corresponding interface VLANs) -> hosts in different VLANs can communicate.

Please rate if it helps.

Thank you,

The point is, there is no router or no layer3 switch.

Only a layer2 switch. So I assume this is impossible this way?

Could only be solved by:

- Using a layer3 switch

or

- Using a router

or

- Using a 2nd ethernet card in the desktop pc

Is that correct?

Yes You are absolutely right.

Router or layer3 switch or 2 NICs will solve tthis problem.
