Hi,

Usually vlan interfaces have a ‘.’ in their names. So it isn’t possible to get information (like address) from jinja form because ‘.’ is used to access attributes.  
Instead of having vlan interface like a physical in facts, I suggest to have something like this:

“ansible\_eth2”: {  
“active”: true,  
“device”: “eth2”,  
“macaddress”: “00:11:22:33:44:55”,  
“module”: “ixgbe”,  
“mtu”: 1500,  
“promisc”: false,  
“type”: “ether”,  
“vlans”: {  
“2111”: {  
“device”: “eth2.2111”,  
“ipv4”: {  
“address”: “10.118.5.241”,  
“netmask”: “255.255.255.0”,  
“network”: “10.118.5.0”  
},  
“ipv4\_secondaries”:   
},  
“2112”: {  
“device”: “eth2.2112”,  
“ipv4”: {  
“address”: “10.118.6.241”,  
“netmask”: “255.255.255.0”,  
“network”: “10.118.6.0”  
},  
“ipv4\_secondaries”:   
}  
}  
}

What do you think about this ?

Did you tried hostvars[‘hostname’][‘ansible\_eth2.2111’][‘ipv4’][‘address’]? It works fine for interfaces with ‘.’ in name.

Yes I tried. It works fine when ‘hostname’ is an another host. If ‘hostname’ is the host on which playbook is running it becomes complex.
