loop-protection vs BPDU Protection

[PEI_1]

Hi,

I have read about both loop-protection and BPDU protection can help to stop broadcast.

Please advise the difference and which one should i use to prevent BPDU broadcast when a switch is inadvertently plugged into the edge switch.

Thanks
Hannah

Hi Hannah

bpdu protechtion or loop protect unable prevent broadcast packet

loop protech prevent loop on your local network


bpdu protech prevent connection unauthorized (edge switch ,access point,router etc.) network device on your local network.

if you want prevent excessive broadcast packet
you can use broadcast limit command

ProCurve Switch 3500-24(eth-20)# broadcast-limit
<0-99> Enter an integer number for the 'broadcast-limit'
command/parameter.
