cbq - jak smerovat mezi vice razenimi

[Zdenek Havelka]

Dobry den,
          zdanlive jednoduchy dotaz:

Mam nasledujici predstavu:


              +----------------+
              | 1:1 root class | 
              +----------------+
                     |
            --------------------------------+
            |                |              |
        +-------+        +--------+      +-------+
        | SFQ   |        | TBF-a  |      | TBF-b |
        +-------+        +--------+      +-------+
            |
        +-------+
        | TBF-c |
        +-------+


Data na IP adresu A strcim do TBF-a, data na IP adresu B strcim do TBF-b,
vystup obeho privedu do SFQ a z nej do TBF-c

Kdyz to zkousim, narazim na problem pri presunu dat mezi TBF-a(b) -> SFQ, a
dokonce i mezi SFQ -> TBF-c

Konkretne:

$ tc -s qdisc list dev eth1

qdisc tbf 4: rate 64Kbit burst 12Kb lat 5.5s 
 Sent 24010 bytes 245 pkts (dropped 0, overlimits 455) 

 qdisc tbf 3: rate 64Kbit burst 12Kb lat 5.5s 
 Sent 24696 bytes 252 pkts (dropped 0, overlimits 444) 

 qdisc tbf 5: rate 64Kbit burst 12Kb lat 5.5s 
 Sent 0 bytes 0 pkts (dropped 0, overlimits 0) 

 qdisc sfq 2: quantum 1500b perturb 1sec 
 Sent 0 bytes 0 pkts (dropped 0, overlimits 0) 

 qdisc cbq 1: rate 100Mbit (bounded,isolated) prio no-transmit
 Sent 49042 bytes 505 pkts (dropped 0, overlimits 678) 
  borrowed 0 overactions 0 avgidle 62 undertime 0

Zcela zjevne jdou data jen do TBF-a a TBF-b

Asi jsem neco nepochopil, muzete mi nekdo osvetlit, co je spatne na
konfiguraci v attach ?
