Adding VLANs thru EOS SDK API

[krzysztof-sprzaczkowski]

Hi,
How to get VLAN added thru SDK API (trunk_vlan_set() method of eth_intf_mgr) visibled on the global list of vlans (CLI: show interface vlans)? It is only visible as local configuration parameter of the interface (CLI: show active). Is there any additional SDK API method which has to be called to add VLAN to the global list of vlans? I can see that adding VLAN thru CLI to allowed VLANs on the intefrace (CLI: switchport trunk allowed vlan 3000), it is required to perform the second command (CLI: vlan 3000) to see it on the global list of vlans (CLI: show interface vlans).

e.g.
localhost(config)#interface Ethernet 1/2
localhost(config-if-Et1/2)#show active
interface Ethernet1/2
switchport trunk native vlan 1000
switchport trunk allowed vlan 1000,2000
switchport mode trunk
localhost(config-if-Et1/2)#show interface vlans
Port Untagged Tagged
Et1/2 1000 2000
localhost(config-if-Et1/2)#switchport trunk allowed vlan 1000,2000,3000
localhost(config-if-Et1/2)#show active
interface Ethernet1/2
switchport trunk native vlan 1000
switchport trunk allowed vlan 1000,2000,3000
switchport mode trunk
localhost(config-if-Et1/2)#show interface vlans

Et1/2 1000 2000
localhost(config-if-Et1/2)#vlan 3000
localhost(config-vlan-3000)#exit
localhost(config)#show interface vlans

Et1/2 1000 2000,3000

Allowing a vlan on an interface does not also implicitly create the vlan itself, so at that point it is just a forward reference. I browsed through the code and could not find an api to create the vlan itself, so I guess you have to preconfigure those via the cli, for now. Not sure why we thought such api is not needed, or if it just fell through a crack, I will have to ask around.
