broadcast storm recovery mode. When you specify Enable for Broadcast
Storm Recovery and the broadcast traffic on any Ethernet port exceeds
20 percent of the link speed, the switch blocks (discards) the broadcast
traffic until the broadcast traffic returns to 10 percent or less.
Upper limit for 10M link is 20% and lower limit is 10%.
For 100M link Upper limit is 5% and lower limit is 2%
