## Improve validator
- `set service dhcpv6-server shared-network-name foo subnet 2001:db8:201::/64 lease-time default 3000` a number is supplied by CLI treads value as a string this should be checked
- `set service dhcpv6-server shared-network-name foo subnet 2001:db8:201::/64 lease-time maximum 3000` a number is supplied by CLI treads value as a string this should be checked
- `set service dhcpv6-server shared-network-name foo subnet 2001:db8:201::/64 lease-time minimum 3000` a number is supplied by CLI treads value as a string this should be checked
## Migrate CLI
- `set service dhcpv6-server shared-network-name foo subnet 2001:db8:201::/64 sip-server-address|sip-server-name` do the same for the user - only the backend is rendered in a different way. This will be migrated to a new `sip-server` configuration node. This needs updated documentation
- [x] Implement & migrate CLI
- [ ] update documentation @s.lorente
