automaxidle in CBQ

[Tarik Alj <aljtarik@ozias.inrs-telecom.uquebec.ca>]

Hi all,

	i have a problem using the insert method with cbq links; here's a sample 
of my script:
	
    29	set n1 [$ns node]
    30  set n2 [$ns node]
    31
    32  
    33
    34
    35  $ns simplex-link $n1 $n2 1Mb 100ms CBQ
    36  set cbqlink [$ns link $n1 $n2]
    37
    38  
    39 
    40  
    41  
    42
    43  set topClass [new CBQClass]
    44  set lowerClass1 [new CBQClass]
    45  set lowerClass2 [new CBQClass]
    46
    47  
    48  $topClass setparams none 0 0.98 auto 8 2 0
    49  $lowerClass1 set params $topClass true 0.35 auto 1 1 150ms; 
    50  $lowerClass2 set params $topClass true 0.55 auto 2 1 250ms
    51
    52  
    53
    54  set q1 [new Queue/DropTail]
    55  $q1 set limit_ 20
    56  set q2 [new Queue/DropTail]
    57  $q2 set limit_ 30
    58
    59  $lowerClass1 install-queue $q1
    60  $lowerClass2 install-queue $q2
    61
    62  $cbqlink insert $topClass
    63  $cbqlink insert $lowerClass1
    64  $cbqlink insert $lowerClass2
    
    Now when i try to run the script i get the error message:
    
    can't read "maxidle_": no such variable
    while executing
"if { $maxidle_ == "auto" } {
$cbqcl automaxidle [$link_ set bandwidth_]  [$queue_ set maxpkt_]
set maxidle_ [$cbqcl set maxidle_]
}"
    (procedure "_o16" line 38)
    (CBQLink insert line 38)
    invoked from within
"$cbqlink insert $lowerClass1"
    (file "cbq00.tcl" line 63)

	The peculiar thing thought is that the compiler is not complaining about 
the insert at line 62 but at line 63. When i try to change the setting in 
setparams to a numeric value instead of auto, i get the same complaint. Can 
anybody tell me what i have been doing wrong, if i have?
    
thanks,

Tarik
