[c-nsp] Performace - IP DHCP Snooping

[Alan Buxey]

hi,

havent noticed any issues with having DHCP snooping enabled - performance
wise the access layer seemed to be the same with or without it (its
very quick and easy for these switches to see particular bits of
packets). just ensure that your trunks are trusted (we too do the whole
vlan range rather than only particular ones that a switch may actually
handle - makes deployment easier and stops nasty gotchas like
an edge port being put onto a vlan that has no snooping
protection because the person who added it didnt then update the
switch config...)
