Switch (enable) show trunk 2/1 detail * - indicates vtp domain mismatch Port Mode Encapsulation Status Nativevlan -------- ----------- ------------- ------------ ----------- 2/1 auto dot1q not-trunking 15
Port Peer-Port Mode Encapsulation Status -------- --------- ----------- ------------- ------------ 2/1 unknown unknown unknown unknown
