NOTE: Path cost "0" is used to indicate auto-configuration mode. When the short path
cost method is selected and the default path cost recommended by the IEEE 8021w
standard exceeds 65,535, the default is set to 65,535.
By default, the system automatically detects the speed and duplex mode used on
each port, and configures the path cost according to the values shown below.

SNMP Configuration
Simple Network Management Protocol (SNMP) is the protocol developed to manage
nodes (servers, workstations, routers, switches and hubs etc.) on an IP network. SNMP
enables network administrators to manage network performance, find and solve
network problems, and plan for network growth. Network management systems
learn of problems by receiving traps or change notices from network devices
implementing SNMP.
