Study Notes
Dynamic Trunking Protocol (DTP)
- DTP is a standard protocol supported by all network switches, helping to automatically turn a link into a trunk link between two switches.
Switchport Modes
- Switchport mode trunk allows a port to be an access port.
- Switchport mode dynamic desirable continuously attempts to become a trunk port using DTP.
- Switchport mode dynamic auto will not attempt to form a trunk if it receives a DTP trunk request from the connected device.
- Switchport mode dynamic means the port will negotiate whether it should be an access or trunk port.
DTP Negotiation
- By default, DTP negotiation process turns all links into trunk links.
- If a switch does not support DTP, the link will automatically become an access link.
- Using 'switchport nonegotiate' prevents the interface from generating DTP frames when the switchport mode is dynamic auto.
VLAN Trunking
- In VLAN trunking, packets are forwarded between switches based on the VLAN identifier, not IP address.
- Each VLAN traffic would require a dedicated link for transmission if trunk links are not available.
- The packet identifier (ID) added within the header of packets holds information about the VLAN membership of each packet.
- IEEE 802.1Q is a standard protocol for VLAN trunking, not proprietary to Cisco.
- On some old Cisco switches, only ISL protocol is supported for VLAN trunking.
- An access port in Cisco switches can only belong to one VLAN.
