Port Type and Link Type

For use in RSTP, MSTP, and PVRST modes, BLADEOS Spanning Tree configuration includes parameters for edge port and link type.

Note – Although edge port and link type parameters are configured with global commands on ports, they only take effect when RSTP, MSTP, or PVRST is turned on.

Edge Port

A port that does not connect to a bridge is called an edge port. Since edge ports are assumed to be connected to non-STP devices (such as directly to hosts or servers), they are placed in the forwarding state as soon as the link is up.

Edge ports send BPDUs to upstream STP devices like normal STP ports, but should not receive BPDUs. If a port with edge enabled does receive a BPDU, it immediately begins working as a normal (non-edge) port, and participates fully in Spanning Tree.

Use the following commands to define or clear a port as an edge port:

RS G8124(config)# interface port <port>

RS G8124(config-if)# [no] spanning-tree edge

RS G8124(config-if)# exit

Link Type

The link type determines how the port behaves in regard to Rapid Spanning Tree. Use the following commands to define the link type for the port:

RS G8124(config)# interface port <port>

RS G8124(config-if)# [no] spanning-tree link-type <type>

RS G8124(config-if)# exit

where type corresponds to the duplex mode of the port, as follows:

p2p	A full-duplex link to another device (point-to-point)

shared A half-duplex link is a shared segment and can contain more than one device.

auto The switch dynamically configures the link type.

Note – Any STP port in full-duplex mode can be manually configured as a shared port when connected to a non-STP-aware shared device (such as a typical Layer 2 switch) used to interconnect multiple STP-aware devices.
