I am trying to enable the applicance mode with the following CLI command as per the online documentation:
C:\Users\Pablo>aws ec2 modify-transit-gateway-vpc-attachment --transit-gateway-attachment-id tgw-attach-0b6cb80499a53XXXX --options ApplianceModeSupport=enable
Parameter validation failed:
Unknown parameter in Options: "ApplianceModeSupport", must be one of: DnsSupport, Ipv6Support
I tried changing the DnsSupport option to make sure I'm in the right region and transit gateway attach and works:
C:\Users\Pablo>aws ec2 modify-transit-gateway-vpc-attachment --transit-gateway-attachment-id tgw-attach-0b6cb80499a5383e9 --options DnsSupport=disable
{
"TransitGatewayVpcAttachment": {
"TransitGatewayAttachmentId": "tgw-attach-0b6cb80499a53XXXX",
"TransitGatewayId": "tgw-01e5ee317cd46YYY3",
"VpcId": "vpc-02e3c21f4d7dacZZZ",
"VpcOwnerId": "95107885XXXX",
"State": "modifying",
"SubnetIds": [
"subnet-0c24bb7aae4deeXXX",
"subnet-064acc2ad5667aXXX",
"subnet-03b6351363cd1cXXX"
],
"CreationTime": "2022-09-27T18:09:59+00:00",
"Options": {
"DnsSupport": "disable",
"Ipv6Support": "disable"
}
}
}
It looks like this transit gateway attachment does not have this option. What am I doing wrong?
I got the same response including the region, in fact, I tried it before. As for the second command:
