Hello,
I'm testing IOS XE 16.12.1 in a WS-C3850-24XS. When I tried to use object-group, it does not accept IPv6 network addresses. IPv4 works as expected:
object-group network netA-4 10.1.0.0 255.255.254.0 10.1.20.0 255.255.254.0 host 10.1.10.1
But if fails to accept IPv6 networks:
object-group v6-network netA-6 switch1(config-v6network-group)#fdca:aaaa:aaaa:aaaa::/64 ^ % Invalid input detected at '^' marker. switch1(config-v6network-group)#host fdca:aaaa:aaaa:aaaa::1 switch1(config-v6network-group)#
I can only add hosts to object-group v6-network. I tried both ULA and global addresses, different mask and nothing seems to be accepted.

Hi,
What is your license? For IPv6 features, you usually need IP Services license.

I'm using IP Base. However, AFAIK, IP Base lacks stuff like dynamic routing and other enterprise features.
IPv6 seems to be now a "standard feature" and not an "add-on feature", not something to buy as extra.
It does not make sense to avoid using object-group IPv6 network but allow the same result using individual ACEs.
object-group only simplifies ACL management, not a final feature. If it were something that we need to "buy", I would expect it to offer IPv6 prefix/network match before it allows individual IPv6 host match, as the later uses more resources.
