Redundancy protocol – RSTP
The Lynx switch support the Rapid Spanning Tree Protocol (RSTP) according to
IEEE802.1w with fallback to the Spanning Tree Protocol (STP - IEEE802.1D).
The STP fallback feature means that the Lynx switches can be used together
with switches that only have support for STP.
For more information on RSTP, please read the Whitepaper found on the enclosed Lynx CD
or at the Westermo website.
Available options are:
Bridge Prio The switch with the lowest priority will become the root switch.
Dynamic Dynamic trunking is enabled when RSTP is used in a VLAN to
eliminate failure
Trunking due to an incorrectly configured VLAN. If every unit in the ring has
enabled Dynamic trunking, all VLANs will be granted access on the
ring.
Edge Ports Selection of edge ports for RSTP.
Disable RSTP This option disables RSTP.
Click the "Apply" button to confirm changes made to the Redundancy Protocol settings.
The unit needs to be restarted before changes can take affect.
