NS3552-8P-2S-V2 User Manual
You can modify each port state by using management software. When STP is enabled,
every port on every switch in the network goes through the blocking state and then
transitions through the states of listening and learning at power up. If properly
configured, each port stabilizes to the forwarding or blocking state. No packets (except
BPDUs) are forwarded from, or received by, STP-enabled ports until the forwarding
state is enabled for that port.
STP parameters
STP operation levels
The industrial managed switch allows for two levels of operation: the switch level and
the port level. The switch level forms a spanning tree consisting of links between one or
more switches. The port level constructs a spanning tree consisting of groups of one or
more ports. The STP operates in much the same way for both levels.
Note:
On the switch level, STP calculates the bridge identifier for each switch and then
sets the root bridge and the designated bridges. On the port level, STP sets the root
port and the designated ports.
