Hey there.
DTP is such an easy protocol . There are only few commands to enable or disable it. I've been reading so much crap about this since my CCNA on cisco forums that I d like to discuss about it with you guys. Some people says that DTP can only be shutted with the command switchport nonegotiage. Some people says that DTP can only be shutted with the command switchport mode access .... I disagree and I noticed that switchport mode access did indeed shut the DTP process .... Rack1SW1(config-if)#do sh int fa0/21 sw Name: Fa0/21 Switchport: Enabled Administrative Mode: static access Operational Mode: static access Administrative Trunking Encapsulation: dot1q Operational Trunking Encapsulation: native *Negotiation of Trunking: Off* Access Mode VLAN: 1 (default) Trunking Native Mode VLAN: 146 (VLAN0146) Administrative Native VLAN tagging: enabled Voice VLAN: none Administrative private-vlan host-association: none Administrative private-vlan mapping: none Administrative private-vlan trunk native VLAN: none Administrative private-vlan trunk Native VLAN tagging: enabled Administrative private-vlan trunk encapsulation: dot1q Administrative private-vlan trunk normal VLANs: none Administrative private-vlan trunk associations: none Administrative private-vlan trunk mappings: none Operational private-vlan: none Trunking VLANs Enabled: ALL Pruning VLANs Enabled: 2-1001 Capture Mode Disabled So what do you guys think about this newbie question ? :) -- Nicolas MICHEL Ingenieur Réseaux et Securité (CCNA/CCNP) _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
