I am trying to use the cdp neighbor information gathered in cisco.ios.ios\_facts to configure the descriptions on the interfaces that are relevant to the neighbors. in the following code, I can iterate through the interfaces with neighbors on them just fine, but I cannot get the descriptions to parse through the “hosts” that are given in the output. I can reference each member of the list, or put every member of the list on each line, but I am having trouble getting the hosts/interfaces to line up. Much of the following code is filled with my attempts to understand what output I get with each debug statement. ```auto code --- l PLAY [Update Interface Descriptions] ******************************************************************************************************************************************************************************************************** TASK [Gather Facts] ************************************************************************************************************************************************************************************************************************* ok: [10.140.1.92] TASK [set_fact] ***************************************************************************************************************************************************************************************************************************** ok: [10.140.1.92] TASK [debug] ******************************************************************************************************************************************************************************************************************************** ok: [10.140.1.92] => (item=GigabitEthernet0/1) => { "msg": "GigabitEthernet0/1" } ok: [10.140.1.92] => (item=GigabitEthernet0/14) => { "msg": "GigabitEthernet0/14" } ok: [10.140.1.92] => (item=GigabitEthernet0/9) => { "msg": "GigabitEthernet0/9" } TASK [debug] ******************************************************************************************************************************************************************************************************************************** ok: [10.140.1.92] => (item=[{'host': 'SEPDCEB94BC2486', 'platform': 'Cisco IP Phone 8811', 'port': 'Port 1', 'ip': '10.140.50.45'}]) => { "msg": [ [ { "host": "SEPDCEB94BC2486", "ip": "10.140.50.45", "platform": "Cisco IP Phone 8811", "port": "Port 1" } ] ] } ok: [10.140.1.92] => (item=[{'host': 'USACRSSRFSW090.newmont.net', 'platform': 'cisco WS-C4506-E', 'port': 'GigabitEthernet6/41', 'ip': '10.140.253.252'}]) => { "msg": [ [ { "host": "USACRSSRFSW090.newmont.net", "ip": "10.140.253.252", "platform": "cisco WS-C4506-E", "port": "GigabitEthernet6/41" } ] ] } ok: [10.140.1.92] => (item=[{'host': 'GQ_NET_Office', 'platform': 'cisco C9130AXI-B', 'port': 'GigabitEthernet0', 'ip': '10.140.14.87'}]) => { "msg": [ [ { "host": "GQ_NET_Office", "ip": "10.140.14.87", "platform": "cisco C9130AXI-B", "port": "GigabitEthernet0" } ] ] } TASK [Merge provided configuration with device configuration] ******************************************************************************************************************************************************************************* ok: [10.140.1.92] => (item={'msg': 'GigabitEthernet0/1', 'failed': False, 'changed': False, 'item': 'GigabitEthernet0/1', 'ansible_loop_var': 'item'}) ok: [10.140.1.92] => (item={'msg': 'GigabitEthernet0/14', 'failed': False, 'changed': False, 'item': 'GigabitEthernet0/14', 'ansible_loop_var': 'item'}) ok: [10.140.1.92] => (item={'msg': 'GigabitEthernet0/9', 'failed': False, 'changed': False, 'item': 'GigabitEthernet0/9', 'ansible_loop_var': 'item'}) PLAY RECAP ********************************************************************************************************************************************************************************************************************************** 10.140.1.92 : ok=5 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0 ``` ---

Here is a cleaned up version of the mess I had created earlier. What I am trying to accomplish is the following: I want to gather cdp neighbor information, then write that cdp neighbor info in the description of the corresponding interface. \\ * * * - name: CDP Neighbor information hosts: trial tasks: \\ Output: PLAY [CDP Neighbor information] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* TASK [Gather Facts] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ok: [10.140.1.92] TASK [debug] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ok: [10.140.1.92] =\> { “msg”: { “GigabitEthernet0/1”: [ { “host”: “SEPDCEB94BC2486”, “ip”: “10.140.50.45”, “platform”: “Cisco IP Phone 8811”, “port”: “Port 1” } ], “GigabitEthernet0/14”: [ { “host”: “USACRSSRFSW090”, “ip”: “10.140.253.252”, “platform”: “cisco WS-C4506-E”, “port”: “GigabitEthernet6/41” } ], “GigabitEthernet0/9”: [ { “host”: “GQ\_NET\_Office”, “ip”: “10.140.14.87”, “platform”: “cisco C9130AXI-B”, “port”: “GigabitEthernet0” } ] } } TASK [debug] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* fatal: [10.140.1.92]: FAILED! =\> {“msg”: “dict object has no element 0. dict object has no element 0”} PLAY RECAP \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* 10.140.1.92 : ok=2 changed=0 unreachable=0 failed=1 skipped=0 rescued=0 ignored=0 \\ I cannot figure out how to iterate through each interface AND assign the descriptions accordingly. I can iterate through the interfaces, but wind up either putting ALL of the neighbors in all of the descriptions, OR putting a select neighbor on all of the descriptions. I see it print out beautifully in the first debug, but I can’t find the way to access that and use it elsewhere in the playbook. ---

@shicks Thank you for the details. How about below tasks: ```yaml - name: CDP Neighbor information hosts: trial tasks: - name: Gather Facts cisco.ios.ios_facts: gather_subset: - all gather_network_resources: - interfaces - name: Configure interfaces cisco.ios.ios_interfaces: config: - name: "{{ item.key }}" description: "to {{ item.value[0].host }} {{ item.value[0].ip }}" # customizable loop: "{{ ansible_net_neighbors | dict2items }}" ``` ---

I have tried similar formats, and I tried the above this morning. I keep getting a “The error was: ‘item’ is undefined.” message. I have tried several iterations of this and get the same “item is undefined error.” I have manipulated this code many times, and get close, but can’t seem to get this across the finish line. ``` - name: Configure interfaces cisco.ios.ios_interfaces: config: - name: "{{ item.key }}" description: "to {{ item.value[0].host }} {{ item.value[0].ip }}" # customizable loop: "{{ ansible_net_neighbors | dict2items }}" ``` the problem seems to be here somewhere, but I don’t know how to fix it… ---

@shicks It seems indent of `loop` is wrong. Please ensure. ```auto - name: Configure interfaces cisco.ios.ios_interfaces: config: - name: "{{ item.key }}" description: "to {{ item.value[0].host }} {{ item.value[0].ip }}" # customizable loop: "{{ ansible_net_neighbors | dict2items }}" ``` ---
