SWITCH PORT MODES

1.      ACCESS — Puts the LAN port into permanent non-trunking mode  i.e. Access port

2.      Trunk — Puts the LAN port into permanent trunking mode and negotiates to convert the link into a trunk link. The LAN port becomes a trunk port even if the neighbouring port does not agree to the change.

3.      Dynamic Auto — Makes the LAN port willing to convert the link to a trunk link. The LAN port becomes a trunk port if the neighbouring LAN port is set to trunk or dynamic desirable mode.

4.      Dynamic Desirable — Makes the LAN port actively attempt to convert the link to a trunk link. The LAN port becomes a trunk port if the neighbouring LAN port is set to trunk, dynamic desirable, or dynamic auto mode. This is the default mode for all LAN ports.

5.      Nonegotiate — Puts the LAN port into permanent trunking mode but prevents the port from generating DTP frames. You must configure the neighbouring port manually as a trunk port to establish a trunk link.
