STP Bridge Global Settings
To open the following window, click L2 features > Spanning Tree > STP Bridge Global Settings:
In this window, the following parameters can be configured:
Parameter Description
STP State Use the radio buttons to enable or disable the STP Status.
STP Version Use the pull-down menu to choose the desired version of STP to be
implemented on the Switch. There are three choices:
STP - Select this parameter to set the Spanning Tree Protocol (STP) globally
on the switch.
RSTP - Select this parameter to set the Rapid Spanning Tree Protocol (RSTP)
globally on the Switch.
MSTP - Select this parameter to set the Multiple Spanning Tree Protocol
(MSTP) globally on the Switch.
Forwarding BPDU This field can be Enabled or Disabled. When Enabled, it allows the forwarding
of STP BPDU packets from other network devices. The default is Enabled.
Bridge Max Age (6-40) The Max Age 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. If the value ages out and a
BPDU has still not been received from the Root Bridge, the Switch will start
sending its own BPDU to all other switches for permission to become the Root
Bridge. If it turns out that your switch has the lowest Bridge Identifier, it will
become the Root Bridge. The user may choose a time between 6 and 40
seconds. The default value is 20.
Bridge Hello Time (1 – 2 Sec) The Hello Time can be set from 1 to 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. Note: The Global Bridge Hello Time
is only configurable if the DUT function is running in STP/RSTP mode.
Bridge Forward Delay
(4-30)
The Forward Delay can be from 4 to 30 seconds. Any port on the Switch
spends this time in the listening state while moving from the blocking state to
the forwarding state.
Tx Hold Count (1-10) Used to set the maximum number of Hello packets transmitted per interval.
The count can be specified from 1 to 10. The default is 6.
Max Hops (6-40) Used to set the number of hops between devices in a spanning tree region
before the BPDU (bridge protocol data unit) 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 BPDU packet
and the information held for the port will age out. The user may set a hop
count from 6 to 40. The default is 20.
