An IPv6 NetStream-enabled device mustperiodically resend the updated template to NetStream servers. The server cannot associate the statisticswith their proper fields when the following conditions exist:• The version 9 template is changed on the IPv6 NetStream-enabled device.• The version 9 template is not updated on NetStream servers.To avoid this situation, configure the refresh frequency (in packets), the refresh interval (in seconds), orboth for version 9 templates so that NetStream servers can refresh them.
