DHCP APM iApps template

Hello,

 

I try to use the DHCP APM iApps. Each time the AP execute the irule imported with the iApps , I receive the followinf error message :

 

Nov 9 12:44:33 TOTOTOT err tmm6[5516]: 01220001:3: TCL error: /Common/ir-apm-dhcp-policy <ACCESS_POLICY_AGENT_EVENT> - Command must start with connect.invalid connection handle (line 1)    invoked from within "close $cid "    ("foreach" body line 10)    invoked from within "foreach {svr} $dhcp_svrs {     set sts ""     if {[catch {connect -protocol UDP -myport 67 -status sts -idle 30 "${svr}:67"} cid] ||         ($cid ..."    ("DHCP_req" arm line 133)    invoked from within "switch [ACCESS::policy agent_id] {  "DHCP_req" {   ACCESS::session data set session.dhcp.address "" ; #moriturus te saluto    set e ""   if {([set..."

 

The main error seem to be the

 

Command must start with connect.invalid connection handle (line 1)    invoked from within "close $cid "

 

Does somebody have an idea how tioo solve the problem, and have somebody ised this iApss to allow the APM module use dhcp scope on external DHCP server ?

    i assume this about this iApp?

     

    https://devcentral.f5.com/s/articles/APM-DHCP-Access-Policy-Example-and-Detailed-Instructions

     

    version 3d+, 2018-10-10 ?

     

    you followed it as described in the article, added IP address in variables as suggested?

     

    can you share your TMOS version?

      can you check with tcpdump or the the /var/log/ltm log if a DHCP request is send?

        Hi boneyard,

        Thank you for your answer but with the tcl error the irule execution fails and therefore I have no dhcp request.

        I opened a ticket and the support made me change the version of the iApp (v3g) and now the dhcp relay works correctly.
