SNMP test result is fail, because sonic-mgmt tell this reason "ERROR! 'snmp_ports' is undefined"

[dnisqa]

Description

1. SNMP test result is fail, because sonic-mgmt tell this reason "ERROR! 'snmp_ports' is undefined"
2. DUT is Delta-AG9032v1
3. sonic-mgmt build number is 368 from "https://sonic-jenkins.westus2.cloudapp.azure.com/job/bldenv/job/docker-sonic-mgmt/"

Steps to reproduce the issue:

1. "./testbed-cli.sh gen-mg vmst0-1 lab password.txt" produce t0 topology minigraph file.
2. To deploy t0 minigraph file to DUT.
3. To verify T0 - 4VMs has been started and working.
4. ansible-playbook -vvv -i lab -l sonic-ag9032 test_sonic.yml -e "testcase_name=snmp testbed_type=t0 testbed_name=vmst0-1"

Describe the results you received: TASK [test : Verify lldpLocPortTable is present] *** task path: /var/johnar/sonic-mgmt/ansible/roles/test/tasks/snmp/lldp.yml:41 Wednesday 29 August 2018 07:22:19 +0000 (0:00:13.877) 0:09:28.842 ** fatal: [sonic-ag9032]: FAILED! => {"failed": true, "msg": "ERROR! 'snmp_ports' is undefined"}

Describe the results you expected:

1. The snmp test item is pass on old sonic-mgmt(old sonic-mgmt doesn't has snmp/lldp.yml file).
2. lldp table and lldp neighbors status of DUT are normally.

1."./testbed-cli.sh gen-mg vmst0-1 lab password.txt" produce t0 topology minigraph file. 2.To deploy t0 minigraph file to DUT.

@dnisqa, i have two questiones. in step1, where do you get the t0 generated minigraph file? in step2, how do you deploy t0 minigraph file to DUT?

[dnisqa]

Hi Hui:

step1: "./testbed-cli.sh gen-mg vmst0-1 lab password.txt" <= this command will general my sonic switch minigraph file in our sonic-mgmt docker we have setting our sonic switch " manager IP, switch name, switch hwsku, switch speed, and docker-ptf IP in "lab" file of sonic-mgmt. we have setting our topology information (ex:

conf-name,group-name,topo,ptf_image_name,ptf_ip,server,vm_base,dut,comment

   ptf-p1,ptf-p1,ptf32,docker-ptf,192.168.59.181/24,server_1,,sonic-ag9032,SQA Test ptf for sonic-ag9032
   vmst0-1,vmst0-1,t0,docker-ptf,192.168.59.181/24,server_1,VM0100,sonic-ag9032,SQA Test T0 for sonic-ag9032
  ) in testbed.csv of sonic-mgmt

step2: "To deploy minigraph file to DUT" command ./testbed-cli.sh deploy-mg vmst0-1 lab password.txt

Attached file is our minigraph file

[li7hui]

Hi Cheng, I can now generate the minigraph file with this commond:./testbed-cli.sh gen-mg vms-sn2700-t0 lab password.txt However, I got problem when deploy the minigraph file. it has following errors. The very first it has following error: The second time, and the times since the second time, it shows the following errors: where the "config load_minigraph -y" command hangs there.

Could you show me your 'lab' file of sonic-mgmt please?
