 Usage: batctl multicast_mode|mm [0|1]
 
+batctl mcast_flags
+=================
+
+display the local D.A.T. cache
+
+Usage batctl mcast_flags|mf
+
+Example:
+
+Multicast flags (own flags: [...])
+       Originator Flags
+02:04:64:a4:39:c4 [...]
+02:04:64:a4:39:c1 [U46]
+02:04:64:a4:39:c3 [...]
+
+where:
+- Originator: the MAC address of the originating (primary interface)
+		batman-adv node
+- Flags: multicast flags of the according node
+- U: wants all unsnoopable multicast traffic, meaning other nodes need to always
+	forward any multicast traffic destined to ff02::1 or 224.0.0.0/24 to it
+- 4: wants all IPv4 multicast traffic, meaning other nodes need to always
+	forward any IPv4 multicast traffic to it
+- 6: wants all IPv6 multicast traffic, meaning other nodes need to always
+	forward any IPv6 multicast traffic to it
+
+If a node does not have multicast optimizations available (e.g. old batman-adv
+version or optimizations not compiled in), therefore not announcing any
+multicast tvlv/flags, a '-' will be displayed instead of '[...]'.
