RS-232 Console
This Console port is used to connect a management station or
terminal with the switch. Out-of-band management means go
through the RS-232 port. For more information about switch
management, see Section 4 “ Connecting to the Network ”.
Software Concepts
Static Address
This feature allows you to enter the addresses that will not be aged
out. It can confine users on certain ports specified by the system
manager, so that they cannot switch to other ports.
Spanning Tree
Spanning Tree Protocol (STP) is an industry standard that prevents
loops configurations in switched networks. The Spanning Tree
algorithm creates a single path through network by making sure that
if more than one path exists between parts of a network, only one of
those paths is used.
This also permits multiple interswitch links to remain active for data
transport while operating in conjunction with the Spanning Tree
algorithm. The IEEE 802.1d Spanning Tree Protocol support for
redundant backbone connections and loop-free networks simplifies
network configuration and improves fault tolerance.
