between 4 and 30 seconds. By default, this value is 15 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
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 1 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 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 BDPU packet and the information held for the port will age
out.
