In addition to standard Accounting Update stats, mpd is able to provide accounting information for any specified traffic types. Traffic types may be defined using optional third component of mpd-limit's left part.
In accounting requests mpd can provide such attributes: for radius-acct:
mpd-input-packetstraffic type : 64bit input packets counter,
mpd-output-packetstraffic type : 64bit output packets counter,
mpd-input-octetstraffic type : 64bit of input bytes counter,
mpd-output-octetstraffic type : 64bit of output bytes counter,
MPD_INPUT_PACKETStraffic type : 64bit input packets counter,
MPD_OUTPUT_PACKETStraffic type : 64bit output packets counter,
MPD_INPUT_OCTETStraffic type : 64bit input bytes counter,
MPD_OUTPUT_OCTETStraffic type : 64bit output bytes counter.
NOTE: as Typed Accounting Update is implemented on interface layer instead of link as usual Accounting Update, same data will be reported for every link of multilink connection. Some special care should be taken by AAA to not account same traffic twice in multilink case.
For example, specification:
mpd-filter += "1#1=match dst net 10.0.0.0/8", mpd-limit += "in#1#Local=flt1 pass", mpd-limit += "in#2#Biz=all shape 64000 4000",, or for ext-auth:
MPD_FILTER:1#1=match dst net 10.0.0.0/8 MPD_LIMIT:in#1#Local=flt1 pass MPD_LIMIT:in#2#Biz=all shape 64000 4000will instruct mpd to account traffic of two types: "Local" and "Biz". Traffic going from client to the 10.0.0.0/8 network will be accounted as "Local", all other incoming traffic after shaping will be accounted as "Biz". In accounting request mpd will provide to RADIUS something like:
mpd-input-packets = Local:213213 mpd-input-octets = Local:32132132 mpd-input-packets = Biz:21321 mpd-input-octets = Biz:3213213, and for ext-acct:
ACCT_INPUT_PACKETS:Local:213213 ACCT_INPUT_OCTETS:Local:32132132 ACCT_INPUT_PACKETS:Biz:21321 ACCT_INPUT_OCTETS:Biz:3213213
To simplify AAA integration mpd able to return specified traffic types using standard RADIUS attributes. Required traffic type can be specified using mpd-input-acct/mpd-output-acct attributes.
