#turned on.

#Setting the forward delay too small would result in temporary

#loops as the spannign tree algorithm converges. Setting this

#value too large results in longer partitions after the

#spanning tree reconfigures.

#

#The recommended value is 15 sec.

#forward_delay 15 seconds;

#

#maximum_age: This is the time value advertised by this bridge for

#deciding whether to discard spanning tree frames based on

#message age.

#

#If the selected max_age value is too small, then occasionally,

#the spanning tree will reconfigure unnecessarily, possibly

#causing temporary loss of connectivity in the network. If the

#selected value is too large, the network will take longer then

#necessary to adjust to a new spanning tree after a topological

#event such as restarting or crashing of a bridge or link.

#

#The recommended value is 20 sec.

#maximum_age 20 seconds;

#

#route_maximum_age: This parameter determines how often routes

#will be aged out of the learnt route table.

#

#Default : 300 seconds

#route_maximum_age 300 seconds;

#And last, hardwiring the forwarding table with

#specific MAC addresses to discard.
