Field Description
Port No. To configure the parameters of RSTP/STP port, the
administrator should select a physical port number,
assign a priory number, enter the RPC and then
press “Submit” button.
Priority (0~240) Priority field defines the priority of the RSTP/STP
port. The lower the number is, the higher possibility it
will become a root port. There is a default value for
each port.
RFC
(0~200000000)
RPC stands for “Root Path Cost”. The higher the
cost is, the lower possibility it become a root path. In
the general case, the physical port with the higher
bandwidth will be assigned a lower cost.
16.2 Loopback
Detection Settings
This web page provides loopback detection function. When loopback
detection function is enabled and a port received its own BPDU, the
detection agent drops the loopback BPDU and places the interface in
discarding mode. This loopback status can be released automatically, if
auto wake up function is enabled.
