Click Apply to reflect the change.
Choose the link type option. The options available are
Auto, P2P and Share. A full-duplex port is considered to
have a Point-to-Point (P2P) connection. On the other
hand, a half-duplex port is considered to have a shared
connection. The port cannot migrate to the forwarding
state promptly by setting the link type to Shared.
By default, this option is set to Auto.
Choose the port-fast option
as follows.
• Network - The port keeps remain in the non-port-
fast state for three seconds. If no BPDU is received,
the port becomes the port-fast state, and then its
state becomes changed to the forwarding state. If
the port receives the BPDU later, the port becomes
changed to the non-port-fast state.
• Disabled - Always, the port keeps the non-port-fast
state. Always, it waits until the forwarding state.
After that, the forward-time delay occurs.
• Edge - If a link-up occurs, the port directly transits to
the state of spanning-tree forwarding without
waiting for the forward time delay.
• If the interface receives the BPDU later, its operation
state changes to the non-port-fast state. By default,
this option is set to Network.
This parameter enables or disables an option of
Topology Change Notification (TCN) filtering. If a port is
set to the TCN filtering mode, TC events received by a
port are ignored. By default , this option is set to
disabled.
This parameter enables or disables BPDU forwarding.
If enabled, the STP BPDU received are transferred to all
the VLAN member ports with the untagged form.
By default, this option is set to disabled.
Choose the priority value. The range of values to choose
is from 0 to 240. By default, this option is set to 128.
The lower the value, the higher priority will be.
Enter the value of hello time. The range is from 1 to 2
(seconds). the value specifies an interval for a
representative port to wait during periodic
transmissions of each configuration message.
