Catalyst 3550 - SC Gigabit ethernet ports not blocking spanning tree
I have a stack of 7 3550 switches that are in a cluster together. All switches have 2 1000BaseSX modules which are used to link all switches into a ring topology. When the last link is connected, the Gigabit Ethernet interfaces do not calculate and block a port. Portfast is disabled on all Gigabit ethernet interfaces. When the link is connected and the uplink modules are initialised, the system delays for a short time and then all LEDS flash quickly and in unison
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
