switch & swith -globe question

Hi LillyM,

You cannot switch an IP::addr command the way that you were doing it. See this conversation switch statement, [IP::addr], and varying subnet masks.

The class command (class match $trx1), works with Data Groups. The $trx1, is the variable set in your binary scan. So you can switch off of it, but not perform a class match against it.

Try something like this and let us know if it works for you:

when CLIENT_DATA {
set pay1 [TCP::payload 8]
binary scan $pay1 IA4 len1 trx1

if { [IP::addr [IP::client_addr] equals "x.x.x.x/24" ] } {
switch -glob [ $trx1 ] {
"A" { do something }
"B" { do something }
"C" { do something }
default { do something else }
}
}
elseif { [IP::addr [IP::client_addr] equals "y.y.y.y/24" ] } {
switch -glob [ $trx1 ] {
"D" { do something }
"E" { do something }
"F" { do something }
default { do something else }
}
}
}

Hope this helps!

Hi Micheal,

 

 

It gave some error, I am trying to figure them out. If I could, then I will let you know in a few minutes.

 

Otherwise, I will send you the error and the code that I modified.

 

 

Million thanks

Hi again Micheal,

 

 

I am taking the following error for these lines: " switch -glob [$trx1] {"

 

 

[invalid list: list element in quotes followed by "{" instead of space] []

 

 

I will appreciate it if you could help on this too..

 

 

Thanks

 

 

Lilly

You should investigate your binary scan command and possibly log the value to your LTM Log to see what you are getting.

 

 

TCL Reference Manual: binary

4 character ascii command and no problem in it. It seems to me that it is related with switch -globe command and the error also says like this.

 

 

Why do you think it is about binary scan?

 

 

Thanks

Can you post the error that it is logging?

I cannot even load and save this IRULE, I got the following error:

 

 

[invalid list: list element in quotes followed by "{" instead of space] []

 

 

Thanks

You should just need to remove the square braces from the switch string:

when CLIENT_DATA {
set pay1 [TCP::payload 8]
binary scan $pay1 IA4 len1 trx1

if { [IP::addr [IP::client_addr] equals "x.x.x.x/24" ] } {
switch -glob $trx1 {
"A" { do something }
"B" { do something }
"C" { do something }
default { do something else }
}
}
elseif { [IP::addr [IP::client_addr] equals "y.y.y.y/24" ] } {
switch -glob $trx1 {
"D" { do something }
"E" { do something }
"F" { do something }
default { do something else }
}
}
}

I would have thought that the square brackets could have caused that problem.

Can you let us know if Hoolio's suggestion works?

 

Hello All,

 

 

Firstly I want to thank you for your help and suggestions. In that case (the last one ,Hoolio's suggestion I meant) I only compare the $trx with some strings A, B,C etc.

 

But What I really want to do is, comparing with the content of an external file Like "class match $trx1"does.

 

Is this possible?

 

 

Thanks a lot..
