RE: DTP - Interpreting the Question

Hi Guys
Perfect solution Just I add one more command
int fax/x> switchport trunk encap dot1q> switchport mode trunk Switchport
Nonegotiate when you type show int trunk command on this switch you will see
Mode is -On- it and Encapsulation meansyou statically configure the trunk.
also use show int Fax/x switchport command to verify this.Remember 3560
default mode is switchport dynamic auto.
