Are gigastack links treated like any other normal link?\n\nBackground:\nI have 3 3550's that will be gigastacked together. The gigastack will\nbe from (switch A -> Switch B, Switch B -> Switch C, Switch C ->\nSwitch A).\n\nSwitch A will also have a connection back to our "Core A" switch.\nSwitch B will also have a connection back to our "Core B" switch.\n\nAcross those 3 3550's I will have several VLANs running. My questions\nare as follows\n\n1.) Will I need to setup a trunk across the 3550 gigastack links? Is\nthe giagstack link a normal "link" or does it create some type of\nspecial matrix between the switches (i.e. extension of the switches\nbackplan).\n2.) How does spanning tree come into play on this? For example if we\nwere using only one switch one of the links to the core will be\nblocked by spanning tree. Should I expect anything different in a\ngigastack configuration?\n\nThanks\nAmy.
