Note:
The ATX-to-ATX connections must be point-to-point. There
cannot be any other devices on those LAN segments. The ports used
for trunking can be in any order. However, both ends of the ATX-
to-ATX connections must have trunking enabled for the ports that
are being used for the connections.

3.5.2 Disabling Trunking
Disabling trunking on a port causes that port to return to standard
Spanning Tree operation. You must disable trunking on both ends
of the point-to-point connection, otherwise bridging is not
enabled.

To turn off trunking, at the LCM prompt:
Type:
trunk <port-range> off
For example,
trunk 2-4 off
3.6 CONFIGURING MULTICAST STORM PROTECTION
The ATX provides automatic protection against multicast storms.
Multicast storms are excessive broadcasts to all stations, typically
caused by a malfunctioning device. They can result in severe
network performance problems, including causing the network to
crash.

The way you protect against multicast storms is to define an
acceptable rate for multicast traffic across a port. In many ways
this feature is similar to filtering, however, multicast storm
protection does not involve the use of filters.

Each ATX port can be individually configured for automatic
multicast storm protection. You define what level of multicasts the
ATX will recognize as a multicast storm, by specifying the number
of multicast packets that may be transmitted with a given time
period.
