Hi Experts,
I understand the concept of Tagging but just trying to under how does the switch behaves on some adverse scenario's.
I have put forth this table along with my undrestanding. Just wanted to confirm if my understanding is okay.
Lets assume a case that the switch is connected to a packet generator which places some frames on the link towards switch:
Switch Port Operational Status: Access
Vlan : 10 | My understading: |
|
|
| case 1: The switch gets a traffic on that port with a tag : 10 | Since the Switch is configured as an Access port , it would expect a untagged traffic on this port. Since the port receives a tagged traffic, it would drop the packet |
| Case 2: The switch gets a traffic on this port with a tag : 2 | Since the Switch is configured as an Access port , it would expect a untagged traffic on this port. Since the port receives a tagged traffic, it would drop the packet |
| Case 3: The switch gets a traffic on this port with no tag | The Switch process the traffic and attaches the tag Vlan10 when sent over trunk link |
|
|
| Switch Port Operational Status: Trunk |
|
|
|
| case 1: The switch gets a traffic on that port with a tag | The switch removes the tag upon receiving the tagged traffic and processes the traffic (re-tags if it has to be sent over another trunk link or sends as it is if had to be sent to an access port) |
| Case 2: The switch gets a traffic on this port with no tag | The switch takes this traffic as part of Native Vlan and process them. |
Please let me know if I'm okay wiht my understading.
Thanks.
-Vijay
