You are confusing the dot1q trunk protocol with the VLAN Trunking Protocol. VTP, got it?
Curiously, your answer already includes switchport nonegotiate, which disables VTP. But you should use either ISL or 802.1q, you cannot run a trunk without picking one of these. So you were almost there. --- Marcos Hiroshi Umino (mobile) Le 28/05/2013 à 23:05, [email protected] a écrit : > Task 1.2 from the CCNP-to-CCIE Transition kit Switch Lab 3.
