Hello Azharuddin,

the switchport mode trunk is needed in this type of IOS/platform.

it is a question of IOS implementation you can see this command as a workaround.

newer IOS versions don't need it.

Hope to help

Hello Azharuddin,

if you have a C3548 XL device you will need both commands

actually when we use switchport voice vlan that is an implicit trunk or mini trunk of two vlans

Hope to help

thanks for reply Giuseppe,

since the port carries both data and voice traffic,so it is called as implicit trunk?and will my ip phone works fine if i do not configur the port as trunk?
