MST Configuration Identification

This window is used to view and configure the MST configuration identification settings. These settings
will uniquely identify a multiple spanning tree instance set on the switch. The switch initially possesses
one CIST, or Common Internal Spanning Tree, of which the user may modify the parameters for but
cannot change the MSTI ID for, and cannot be deleted.
To view the following window, click L2 Features > STP > MST Configuration Identification, as shown
below:
Description
Select the link type option here. Options to choose from are Auto,
P2P, and Shared. A full-duplex port is considered to have a point-to-
point (P2P) connection. On the opposite, a half-duplex port is
considered to have a Shared connection .The port cannot transit into
the forwarding state rapidly by setting the link type to Shared. By
default this option is Auto.
Select the port fast option here. Options to choose from are Network,
Disabled, and Edge.
•
In the Network mode the port will remain in the non-port-fast
state for three seconds. The port will change to the port-fast state
if no BPDU is received and changes to the forwarding state. If
the port received the BPDU later, it will change to the non-port-
fast state.
•
In the Disable mode, the port will always be in the non-port-fast
state. It will always wait for the forward-time delay to change to
the forwarding state.
•
In the Edge mode, the port will directly change to the spanning-
tree forwarding state when a link-up occurs without waiting for
the forward-time delay. If the interface receives a BPDU later, its
operation state changes to the non-port-fast state.
By default, this option is Network.
Select to enable or disable the TCN filter option. Enabling TC filtering
on a port is useful for an ISP to prevent the external bridge to a core
region of the network, causing address flushing in that region, possibly
because those bridges are not under the full control of the
administrator. When a port is set to the TCN filter mode, the TC event
received by the port will be ignored. By default, this option is Disabled.
Select to enable or disable BPDU forwarding. If enabled, the received
STP BPDU will be forwarded to all VLAN member ports in the
untagged form. By default, this option is Disabled.
Select the priority value here. Options to choose from are 0 to 240. By
default this option is 0. A lower value has higher priority.
Enter the hello time value here. This value must be between 1 and 2
seconds. This value specifies the interval that a designated port will
wait between the periodic transmissions of each configuration
message.
