trunking

[ravi mishra]

can i assign a trunk port to the interface connected to a pc??..i tried it in pkt tracer but strangely it worked with vlan 1 but not with vlan 2 or any other vlan

Hello Ravi,

Well we can create a trunk link between a switch and a pc and allow vlans on the trunk link as well.However in ideal scenarios an access link is always created between the two.

anywayz it would be better if u post ur configuration and what exactly ur trying to achieve.

Thanks

just a simple config.i was checking whether it'd work.

l3 switch 3650

interface FastEthernet0/1
 switchport trunk allowed vlan 1-2
 switchport trunk encapsulation dot1q
 switchport mode trunk

interface Vlan1
 ip address 192.168.1.1 255.255.255.0
!
interface Vlan2
 ip address 192.168.2.1 255.255.255.0
!
interface Vlan3
 ip address 192.168.3.1 255.255.255.0

pc

ip 192.168.2.2

gateway: 192.168.2.1

Just need to know are you able to ping from pc to svi vlan 2,if not then u need to create vlan 2 first.

Thanks

i have created vlan 2 already but still doesnt ping.When i kept vlan 1 ip as 192.168.2.1/24 and tried in trunk mode then it pinged but when in vlan 2 ,,it wouldnt ping.

As said rightly by Florian,your pc should be capable of working with IEEE 802.1q trunks which i don't think the packet tracer pc is...

Thanks

Sure you can.  Of course for it to work correctly, the PC would need to be able to process VLAN tagged frames.

BTW, take anything you do with Packet Tracer with a very large grain of salt.

Hi!

You sure can do that, but it will only work, if your PC is capeable of working with IEEE 802.1q trunks.

The fact that you are able to Ping the PC in VLAN1 and not an VLAN2 is because of the native-vlan configuration of the Switch, which should be by default vlan1.

So the PC receives the Frames for vlan1 untagged as standard Ethernet-Frames and can handle them. The frames for vlan2 however are tagges with a IEEE 802.1q-type tag, so the PC can't recognize them, until you configure him to work with IEEE802.1q

I don't know if Ciscos Packet-Tracers PC is capable of working with the Tags. I think the Servers in Packettracer can.

Best Regards and all the best,

Florian
