TOPOLOGY :
===========
HOST1 —> SWITCH1 —-> SWITCH2 —-> HOST2
A T T A
Vlan3 Vlan3
HOST1->10.1.2.3/24 HOST2 10.1.2.4/24
A = Access port
T = Trunk Port
T = Trunk Port (All vlans are allowed , VLAN1 is Native)
Below is my Doubt :
Here am able to ping from HOST1 to HOST2
Later have changed SWITCH2 Access port vlan id to 4 , now am expecting
HOST1 has to communicate with HOST2 but it is not happening.
Below is my understanding why it has to work. Please correct me if I misunderstood.
Below is the Flow am assuming :
1. Host1 is sending untagged frame to SWICH1 on access port and SWITCH1
Receives the untagged frame on VLAN3 and update its MAC-TABLE.
2. Now SWITCH1 send the untagged frame from Native VLAN1 to SWITCH2.
SWITCH2 receives the untagged frame on Native Vlan1.
Now there is no VLAN associated with Frame so SWITCH2 has to send that from
On its access port but it is not happening.
WHY ?
