why the packet tracer wont show the truck

[yossryhelal]

Hello,

While practicing the VLAN and trunking concepts, I faced issues with the packet tracer not sowing the trunking ports that were assigned.

Any solutions?

Hello @yossryhelal,

Which config do you enter under interfaces ? 

Do you configure vlan ? Do you add vlan id on your trunk? 

With the command sh int status do you see trunk interfaces up/up ?

here is my config

SW1#sh vlan brief
