For each Spanning Tree instance, you can adjust Spanning Tree parameters on a per-port basis.Ī static trunk of any type appears in the Spanning Tree configuration display, and you can configure Spanning Tree parameters for a static trunk in the same way that you would configure Spanning Tree parameters on a non-trunked port. 802.1s (MSTP) Spanning Tree operates on a per-instance basis (with multiple instances allowed per switch). See Outbound traffic distribution across trunked links.Ĩ02.1D (STP) and 802.1w (RSTP) Spanning Tree operate as a global setting on the switch (with one instance of Spanning Tree per switch). (You cannot separately configure individual ports within a trunk for spanning-tree or VLAN operation.)Īll of the switch trunk protocols use the SA/DA (source address/destination address) method of distributing traffic across the trunked links. For a listing of which screens show which trunk types, see How the switch lists trunk data.įor spanning-tree or VLAN operation, configuration for all ports in a trunk is done at the trunk level. All LACP ports in the same trunk group must be either all static LACP or all dynamic LACP.Ī trunk appears as a single port labeled Dyn1(for an LACP dynamic trunk) or Trk1 (for a static trunk of type LACP, Trunk) on various menu and CLI screens.

See Trunk group operation using LACP.Īll ports in the same trunk group must be the same trunk type (LACP or trunk).
