NOTE: The Forward Delay parameter and the Network size are correlated.
Too short of a Forward Delay parameter may result in temporary
loops. Too long of a forward delay may cause the Network to be
unable to resume normal operations in an acceptable amount of
time. Keeping the default value is recommended.
NOTE: The Hello Time parameter enables the Switch to discover link
failures that occur in the Network without over utilizing Network
resources. Too long of a Hello Time may result in normal links
being regarded as invalid when packets drops occur on the links,
which in turn can result in Spanning Tree being locked in a constant
discovery state. Too short of a Hello Time may result in duplicate
configuration information being sent, which increases the Network
load of the Switches and wastes Network resources. Keeping the
default value is recommended.
NOTE: The Max Age parameter allows the Switch to restart the STP
discovery process if no BPDUs are received before the Max
Age expires. Too short of a Max Age may result in the Switches
regenerating Spanning Trees Instances frequently and cause Network
congestions that can be falsely interpreted as link problems. Too long
of a Max Age results in the Switches being unable to find the link
problems in an acceptable period of time, which in turn handicaps
Spanning Tree Instance generation and makes the Network less
adaptive. Keeping the default value is recommended.
NOTE: The TXHold parameter specifies the number of BPDUs to
send during the Hello Time, the value is specified in Packets
per Second. If the TxHold Count is too large the number of
MSTP packets being sent during each Hello Time interval will
occupy excessive Network resources. Keeping the default
value is recommended.
