standard 802.1D Spanning Tree state changes, treating each Trunk
Group as a single 802.1D Spanning Tree port.
802.1D Spanning Tree takes about thirty seconds to resolve which
FN100 ports are to become forwarding ports. As ports within a Trunk
Group become forwarding ports, traffic within the Trunk Group is
momentarily halted to guarantee the first-in, first-out ordering of the
Ethernet packets.
3.7 DISABLING TRUNKING
Use the trunk <PORTS> off command to turn off trunking. For example:
> trunk 2-4 off
3.8 DISPLAYING TRUNKING STATUS
Use the trunk <PORTS> command to check the status of your current
trunking configuration.
FN100 > trunk 2-4
LCM responds:
NOTE
The Fast Network-to-Fast Network connections must be
point-to-point. There cannot be any other devices on those
Ethernets. The ports used for trunking can be in any order.
However, both ends of the Fast Network-to-Fast Network
connections must have trunking turned on for the ports that are
being used for the connections.
