switch has the lowest Bridge Identifier, it will become the Root
Bridge. The user may choose a time between 6 and 40 seconds. The
default value is 20.
Bridge Hello Time: The user may set the time interval between
transmission of configuration messages by the root device, thus
stating that the Switch is still functioning. A time between 1 and 10
seconds may be chosen, with a default setting of 2 seconds.
Bridge Forward Delay: The maximum amount of time (in seconds)
that the root device will wait before changing states. The user may
choose a time between 4 and 30 seconds. The default is 15 seconds.
Port Path Cost: This defines a metric that indicates the relative
cost of forwarding packets to specified port list. The value between
1 and 65535 to determine the cost. The lower the number, the
greater the probability the port will be chosen to forward packets.
The default value is 10.
Port Path Priority: Select a value between 0 and 255 to specify the
priority for a specified port for forwarding packets. The lower the
value, the higher the priority. The default is 128.
SNMP Setting
Simple Network Management Protocol (SNMP) is an OSI Layer 7
(Application Layer) designed specifically for managing and
monitoring network devices. SNMP enables network management
stations to read and modify the settings of gateways, routers, switches,
and other network devices. Use SNMP to configure system features
for proper operation, monitor performance and detect potential
problems in the Switch, switch group or network.
Managed devices that support SNMP include software (referred to as
an agent), which runs locally on the device. A defined set of variables
(managed objects) is maintained by the SNMP agent and used to
