NetComm NP2624M manual Issue on Trunk and Stacking mode

5.4.3Issue on Trunk and Stacking mode

There are Two basic rules here:

1.Stacking members cannot and should not truck each other.

2.Stacking members can trunk with non-stacking members.

The packet traffic between stacking members are transferred only through Giga module. Trunking between stacking members may cause the spanning tree protocol (STP) to alter the topology and change the routed ports. If this happens, Giga port traffic may break and the stacking mechanism will fail.

For non-stacking member, there is no such limitation.
