[javaboy]

is it possible to assign the same port interface to different VLANs?

Can someone explain the below VLAN?

This can happened if the port is config with one data vlan and one voice vlan.

Kindly check the VLAN information. VLAN 50 and Vlan 136 have been assigned with the same port int.

Yes I already see and reply

You can config two vlan under access port 

One data vlan 

Other is voice vlan 

So it normal.

Hi

 Can you show the command "show run config

  Gi0/1"

[Joseph W. Doherty]

As @MHM Cisco World already noted, for an access port, it can be done on a switch that support a voice VLAN in addition to the number port VLAN assignment.

I believe you might see the same results, i.e. multiple VLANs assigned to the same port, if port is a trunk port too.

As @Flavio Miranda requested, showing the concurrent running config would confirm our suspicions.
