Hi, as i understand CE is default mode for vlan and if fabric feature not installed or not enabled - 'mode' option even is not available for setting and can raise an error.

get_vlan() will return the current vlan mode regardless of whether fabricpath is enabled or not. See response from NXAPI sandbox with no fabricpath:

{
"jsonrpc": "2.0",
"result": {
"body": {
"vlanshowrspan-vlantype": "notrspan",
"is-vtp-manageable": "enabled",
"TABLE_vlanbriefid": {
"ROW_vlanbriefid": {
"vlanshowbr-vlanid": 15,
"vlanshowbr-vlanid-utf": 15,
"vlanshowbr-vlanname": "test15",
"vlanshowbr-vlanstate": "active",
"vlanshowbr-shutstate": "noshutdown",
"vlanshowplist-ifidx": "Ethernet1/4"
}
},
"TABLE_mtuinfoid": {
"ROW_mtuinfoid": {
"vlanshowinfo-vlanid": 15,
"vlanshowinfo-media-type": "enet",
"vlanshowinfo-vlanmode": "ce-vlan"
}
}
}

For the module the mode argument is not mandatory so I see no problem with that.

ok, i missed, i thought about setting vlan mode, but already found it in other pull request https://github.com/jedelman8/nxos-ansible/pull/29/files
