Advanced Configuration
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 (Fast Forwarding) – 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 fast forwarding 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
STP-related timeout problems. However, remember that fast forwarding should only
be enabled for ports connected to an end-node device. (Default: Disabled)
Status – Enables/disables STP on this interface. (Default: Enabled).
