Priority
Setting
Description
Factory Default
Scroll list with
acceptable values
Configures the priority for ports having identical path cost.
128
Admin Edge
Setting
Description
Factory Default
Edge / Non-Edge
Configures the operEdge flag to start as set or cleared
(the initial operEdge state when a port is initialized). The
operEdge is a flag indicating whether the port is
connected directly to edge devices or not (no bridges
attached). Transiting to the forwarding state is faster for
edge ports (operEdge set to true) than other ports.
Non-Edge
Auto Edge
Setting
Description
Factory Default
Checked /
Unchecked
Check to enable the bridge to detect edges at the bridge
port automatically. This allows operEdge to be derived
from whether BPDUs are received on the port or not.
Checked
Restricted Role
Setting
Description
Factory Default
Checked /
Unchecked
When checked, the port will not be selected as root port
for the CIST or any MSTI, even if it has the best spanning
tree priority vector. Such a port will be selected as an
alternate port after the root port has been selected. If set,
it can cause lack of spanning tree connectivity. It can be
set by a network administrator to prevent bridges external
to a core region of the network influence the spanning
tree active topology, because those bridges are not under
the full control of the administrator. This feature is also
known as Root Guard.
Unchecked
Restricted TCN
Setting
Description
Factory Default
Checked /
Unchecked
When checked, the port will not propagate received
topology change notifications and topology changes to
other ports. If set, it can cause temporary loss of
connectivity after changes in spanning tree
’s active
topology as a result of persistently incorrect learned
station location information. It is set by a network
administrator to prevent bridges external 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 or the physical link state of the
attached LANs transits frequently.
Unchecked
BPDU Guard
Setting
Description
Factory Default
Checked /
Unchecked
If checked, causes the port to disable itself upon
receiving valid BPDUs. Contrary to the similar bridge
setting, the port Edge status does not effect this setting.
Unchecked
