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.
