hi i have 5 switches and all of that switches it is connected with trunk



switch1---->switch2----->switch3------>switch4------>switch5(layer3)



so on switch i do show running-config and i did not find a one trunk port when i do command show interface trunk get:



Port Mode Encapsulation Status Native vlan Gi0/23 on 802.1q trunking 1 Gi0/24 auto n-802.1q trunking 1



when i try manuel do switch mode trunk on port 0/24 he dont alow me , how he make auto trunk mode??? tnx


by default, switch ports will trunk if capable. i think to help you, you need to post the configuration of interface gi0/23 and gi0/24 from all switches.
