Rapid Spanning Tree Functionality

The Rapid Spanning Tree (RSTP) option is an advanced networking function that shuts
off ports as necessary to prevent data packet loops when more than one network path
is available. If loops are created in an Ethernet network, packets can be circulated
endlessly, consuming all the bandwidth and making the network unusable.
RSTP allows users to create truly redundant connections between any two points in the
network. The radios detect the redundant paths and keep one connection alive for
communications. If the Primary connection fails for any reason, the secondary
connection is quickly transitioned to a state to forward packets, allowing the network to
adapt itself to handle problems without customer intervention.
RTSP uses active communications between network devices to propagate changes in the
network and to cause transitions to occur much more quickly. Because RTSP is an IEEE

Description
Each row of the table corresponds to one match filter allowing up to 8
distinct filters to identify and assign a priority value to received Ethernet
packets. Each filter has several parameters that can be enabled by clicking on
its checkbox. When multiple parameters are enabled, all must match before
the Priority value is assigned to a packet.
The following priority map filter fields are supported:

Priority – The priority value to assign to the received Ethernet
frame if it was not already marked with a priority value and if all
enabled filter fields match.

Source IP Address – A field match occurs for all packets received
from the device with the entered IP address.

Destination IP Address – A field match occurs for all packets
received addressed to the device with the entered IP address.

Source Port No. – A field match occurs for all IP packets received
with this source port value.

Destination Port No. – A field match occurs for all IP packets
received with this destination port value.

Protocol No. – A field match occurs for all IP packets received with
this protocol number.

Packet Length – This field contains 2 sub-fields. An edit box to
enter a packet length threshold, and checkboxes to select whether
a field match occurs if the length of the received packet is less than
the threshold or if it is greater than or equal to the threshold.
