Setting Up and Configuring the Router
L2 Switch Tab
Mirror Port—Select the mirror destination port from the drop-down menu.
RSTP
The RSTP (Rapid Spanning Tree Protocol) protocol prevents loops in the network and dynamically reconfigures which physical links in a switch should forward frames.
System Priority—Enter the system priority from 0 to 61440 in increments of 4096. Valid values are 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768, 40960, 45056, 49152, 53248, 57344, and 61440. The lower the system priority, the more likely the Router is to become the root in the Spanning Tree. The default is 327688.
Hello Time—Enter a number from 1 to 10. The default is 2.
Max Age—Enter a number from 6 to 40. The default is 20.
Forward Delay—Enter a number from 4 to 30. The default is 15.
Force Version—The default protocol version to use. Select Normal (use RSTP) or Compatible (compatible with old STP). The default is Normal.
Protocol Enable—Check this box to enable RSTP on the associated port. The default is unchecked (RSTP disabled).
Edge—Check this box to specify that the associated port is an edge port (end station). Uncheck the box to specify that the associated port is a link (bridge) to another STP device. The default is checked (edge port).
Path Cost—The RSTP path cost for the designated ports. Enter a number from 1 to 200000000, or auto (autogenerated path cost). The default is auto.
