that occur in a specific region before the BPDU is discarded. The 
default value is 20 hops. 
Note: 
1.  The forward delay parameter and the network diameter are correlated. A too small forward 
delay parameter may result in temporary loops. A too large forward delay may cause a 
network unable to resume the normal state in time. The default value is recommended. 
2.  An adequate hello time parameter can enable the switch to discover the link failures occurred 
in the network without occupying too much network resources. A too large hello time 
parameter may result in normal links being regarded as invalid when packets drop occurred in 
the links, which in turn result in spanning tree being regenerated. A too small hello time 
parameter may result in duplicated configuration being sent frequently, which increases the 
network load of the switches and wastes network resources. The default value is 
recommended. 
3.  A too small max age parameter may result in the switches regenerating spanning trees 
frequently and cause network congestions to be falsely regarded as link problems. A too large 
max age parameter result in the switches unable to find the link problems in time, which in 
turn handicaps spanning trees being regenerated in time and makes the network less 
adaptive. The default value is recommended. 
4.  If the TxHold Count parameter is too large, the number of MSTP packets being sent in each 
hello time may be increased with occupying too much network resources. The default value is 
recommended.
