2.2.7.1.1 STP Status
This screen lets you enable
or disable STP.
Modes: Three modes are
available in the drop-down
menu: “STP,” “RSTP”
(Rapid STP) and “MSTP”
(Multiple STP).
If MSTP is enabled, the
following four attributes are
enabled at the same time.
Region Name: This is an
alphanumeric configuration
name.
Revision: This is a
configuration revision
number to identify the region along with Region Name.
Instance ID:
You can configure MSTP on your switch to map multiple VLANs into a single STP
instance.
VLAN Group:
A group associates each of the potential 4094 VlANs to the given instance.
2.2.7.1.2 Current Roots
This screen (not shown) displays information about the current root bridge: MAC address, priority,
maximum age, hello timer, forwarding delay timer and path cost.
2.2.7.1.3 Bridge
Parameters
The spanning-
tree parameters
of BPdU (bridge
protocol data unit)
transmission can
be configured on
this screen.
Hello Time: This
is the interval
between the
generation of
configuration
BPdUs.
Max Age:
This
is a timeout value to be used by all bridges in the lAN.
Forward Delay: This is a timeout value to be used by all bridges in the lAN.
Bridge Priority: This is the switch priority in the lAN.
Transmission Limit: The root switch of the instance always sends a BPdU (or Mrecord) with a
cost of 0 and the transmission limit set to the maximum value.
2.2.7.1.4 Port Parameters
This screen contains a display window to see and edit the current configurations for each port:
Select a port, edit it, then click “Modify” to change the port setting for spanning-tree.
Instance ID: For MSTP (multiple STP) only, configure MSTP on your switch to map multiple
VlANs into a single STP instance.
Path Cost: The valid range is 1 – 65535. The higher cost is more likely to be blocked by STP
if a network loop is detected.
