MCPD generates a warning any time the 'dag-globals dag-ipv6-prefix-len' setting is updated, even if the update is setting it to its current value: warning mcpd[8822]: 01071859:4: Warning generated : Configuring DAG Global IPv6 Prefix Length still might require modification of vlans previously created with the old setting.
Unwanted warning log lines.
On a tenant running on an F5OS system, this will occur any time platform_agent processes a configuration update from the host, provided the 'dag.userconfigipv6prefixlen' DB variable is set to its default value of 'false'. On all platforms, this will occur any time the setting is modified by a user, either explicitly via tmsh or implicitly via an upgrade with the same old value as before.
Ignore the generated warning.
