Using Data Group List in iRule in a Partition

 

Another note: we had to remove the "$::" form the data groups.

 

Is there a syntax for referencing UAT Data Groups in iRules?

 

V10.2 LTM

 

 

 

This fails to use the UAT- Data Groups that are in the UAT partition:

 

iRule in UAT partition.

 

 

 

======================================================

 

Apply SNAT as specified in snatPoolVip for all

 

packets originated from dataGroupSnatSipHa members.

 

Exclude packets addressed to members of

 

dataGroupSnatExcluded.

 

======================================================

 

when CLIENT_ACCEPTED {

 

if { [matchclass [IP::remote_addr] equals $::/UAT/UAT-dataGroupSnatSipHa] }

 

{

 

if { [matchclass [IP::local_addr] equals $::/UAT/UAT-dataGroupSnatExcluded] }

 

{

 

}

 

else

 

{

 

snatpool UAT-snatPoolSipVip

 

}

 

}

 

}

 

 

 

 

This works with the XXX- data groups in the Common Partition.

 

iRule in UAT partition.

when CLIENT_ACCEPTED {

 

if { [matchclass [IP::remote_addr] equals XXX-dataGroupSnatSipHa] }

 

{

 

if { [matchclass [IP::local_addr] equals XXX-dataGroupSnatExcluded] }

 

{

 

}

 

else

 

{

 

snatpool UAT-snatPoolSipVip

 

}

 

}

 

}

    You should also avoid using hyphens in DG names as these are not always correctly interpreted.
