You can set the other configuration flag in router advertisements. When the other config flag is set, attached hosts use stateful autoconfiguration to obtain non-address information. If the managed address configuration flag (see Address Configuration Flag (S-, K-Series)) is set, the attached host uses stateful autoconfiguration to obtain non-address information regardless of the other config flag setting.
This example enables the use of stateful autoconfiguration by attached hosts to obtain non-address information on VLAN 50:
System(su-config)->interface vlan 50 System(su-config-intf-vlan.0.50)->ipv6 nd other-config-flag System(su-config-intf-vlan.0.50)->
