Configuring the Switch

Priority  Defines the priority used for this port in the Spanning Tree Protocol.. If the path cost for all ports on a switch are the same, the port with the highest priority (i..e.., lowest value) will be configured as an active link in the Spanning Tree.. This makes a port with higher priority less likely to be blocked if the Spanning Tree Protocol is detecting network loops.. Where more than one port is assigned the highest priority, the port with lowest numeric identifier will be enabled..

Default: 128

Range: 0-240, in steps of 16

Port Fast  You can enable this option if an interface is attached to a LAN segment that is at the end of a bridged LAN or to an end node.. Since end nodes cannot cause forwarding loops, they can pass directly through to the spanning tree forwarding state.. Specifying Edge Ports provides quicker convergence for devices such as workstations or servers, retains the current forwarding database to reduce the amount of frame flooding required to rebuild address tables during reconfiguration events, does not cause the spanning tree to initiate reconfiguration when the interface changes state, and also overcomes other STA-related timeout problems.. However, remember that Edge Port should only be enabled for ports connected to an end-node device.. (Default: Disabled)

The Port Information display the current status of the ports in the Rapid Spanning Tree..

Port  Displays the port number..

State  Shows if Rapid Spanning Tree has been enabled on this interface..

Status  Displays current state of this port within the Spanning Tree:

•Discarding  Port receives STA configuration messages, but does not forward packets..

•Learning  Porthastransmittedconfigurationmessages for an interval set by the Forward Delay parameter without receiving contradictory information.. Port address table is cleared, and the port begins learning addresses..

•Forwarding  Port forwards packets, and continues learning addresses..

Role  Roles are assigned according to whether the port is part of the active topology connecting the bridge to the root bridge (i..e.., root port), connecting a LAN through the bridge to the root bridge (i..e.., designated port), or is the MSTI regional root (i..e.., master port); or is an alternate or backup port that may provide connectivity if other bridges, bridge ports, or LANs fail or are removed.. The role is set to disabled (i..e.., disabled port) if a port has no role within the spanning tree..

Forward Transitions  The number of times this port has transitioned from the Learning state to the Forwarding state..

Operational Edge Port  This parameter is initialized to the setting for Administrative Edge Port in STP Port Setting detail, but will be set to false if a BPDU is received indicating that another bridge is attached to this port..

Operational Link Type  The operational point-to-point status of the LAN segment attached to this interface.. This parameter is determined by manual configuration or by auto-detection, as described for Administrative Link Type in the STP Port Setting detail..

Click the Detail button to configure Protocol Migration Test and Administrative Link Type.. Use the check box and drop‑down menu provided to enable and select the mode, then click Apply..
