Wow. After using this code ^ and also this (filter 25-28 ports, many
switches relaying transit dhcp packets, not from user ports ;( ):
if( "%{DHCP-Relay-Circuit-Id}" =~ /^0x([0-9a-f]{8})001([9|a|b|c])$/i ) {
handled
}
CPU use by radiusd fell from 70% to 10-15. Great. Thank you Alan for
great dhcp functional ;)
