more frequently - with every Hello packet. BPDU packets are sent
even if a BPDU packet was not received. Therefore, each link
between bridges is sensitive to the status of the link. Ultimately this
difference results in faster detection of failed links, and thus faster
topology adjustment. A draw-back of 802.1d is this absence of
immediate feedback from adjacent bridges.

STP Function: To selecting enable or disable STP function on the
Switch.
Bridge Priority: This value between 0 and 65535 to specify the
priority for forwarding packets. The lower the value, the higher the
priority. The default is 32768.
Bridge Max Age: This value may be set to ensure that old
information does not endlessly circulate through redundant paths in
the network, preventing the effective propagation of the new
information. Set by the Root Bridge, this value will aid in
determining that the Switch has spanning tree configuration values
consistent with other devices on the bridged LAN. If the value ages
out and a BPDU has still not been received from the Root Bridge,
the Switch will start sending its own BPDU to all other switches for
permission to become the Root Bridge. If it turns out that your
