! sampling_map: given at least a router IP, returns a sampling rate

!

! File syntax is key-based. Position of keys inside the same row (rule) is not

! relevant; Spaces are not allowed (ie. 'id = 1' is not valid). The first full

! match wins (like in firewall rules). Negative values mean negations (ie. match

! data NOT entering interface 2: 'in=-2'); 'id' and 'ip' keys don't support

! negative values.

!

! nfacctd: valid keys: id, ip, in, out

!

! sfacctd: valid keys: id, ip, in, out

!

! list of currently supported keys follows:

!

! 'id' SET: sampling rate assigned to a matching packet, flow

! or sample. The result is used to renormalize packet and

! bytes count if [nf|sf]acctd_renormalize configuration

! directive is set to true.

! 'ip' MATCH: in nfacctd this is compared against the source

! IP address of the device originating NetFlow packets;

! in sfacctd this is compared against the AgentId field

! of received sFlow samples. Expected argument are an IP

! address or prefix (ie. XXX.XXX.XXX.XXX/NN).0.0.0.0/0

! would match all IPv4 addresses; ::/0 would match all

! IPv6 addresses.

! 'in' MATCH: Input interface

! 'out' MATCH: Output interface

!

!

! Examples:

!

id=1024 ip=192.168.1.1

id=2048 ip=192.168.2.1 in=5

id=4096 ip=192.168.3.1 out=3
