The fields that can be configured for STP Priority are described below:
Parameter Description
Priority
Select the STP priority value here. This value is between 0 and 61440. By
default, this value is 32768. The lower the value, the higher the priority.

The fields that can be configured for
STP Configuration are described below:
Parameter Description
Bridge Max Age Enter the bridge Maximum Age value here. This value must be between 6 and
40 seconds. By default, this value is 20 seconds. The Maximum Age value may
be set to ensure that old information does not endlessly circulate through
redundant paths in the network, preventing the effective propagation of the new
information. Set by the Root Bridge, this value will aid in determining that the
Switch has spanning tree configuration values consistent with other devices on
the bridged LAN.
Bridge Hello Time After selecting RSTP/STP as the Spanning Tree Mode , this parameter will be
available. Enter the bridge Hello Time value here. This value must be between
1 and 2 seconds. By default, this value is 2 seconds. This is the interval
between two transmissions of BPDU packets sent by the Root Bridge to tell all
other switches that it is indeed the Root Bridge. This field will only appear here
when STP or RSTP is selected for the STP version. For MSTP, the Hello Time
must be set on a port per-port basis.
Bridge Forward Time Enter the bridge Forwarding Time value here. This value must be between 4
and 30 seconds. By default, this value is 15 seconds. Every port on the Switch
spends this time in the Listening state while moving from the Blocking state to
the Forwarding state.
TX Hold Count Enter the Transmit Hold Count value here. This value must be between 1 and
10 times. By default, this value is 6 times. This value is used to set the
maximum number of Hello packets transmitted per interval.
Max Hops
Enter the maximum number of hops that are allowed. This value must be
between 6 and 40 hops. By default, this value is 20 hops. This value is used to
set the number of hops between devices in a spanning tree region before the
Bridge Protocol Data Unit (BPDU) packet sent by the Switch will be discarded.
Each Switch on the hop count will reduce the hop count by one until the value
reaches zero. The Switch will then discard the BDPU packet and the
information held for the port will age out.
NNI BPDU Address Select the NNI BPDU Address option here. Options to choose from are Dot1d
and Dot1ad . By default, this option is Dot1d . This parameter is used to
determine the BPDU protocol address for STP in the service provider network.
It can use an 802.1d STP address and an 802.1ad service provider STP
address.
