Switch management methods
The 2109 Model S16 Switch can be managed using several remote and local
access methods. If your switch has a front panel display, it can be managed locally
using the front panel buttons. See your switch reference manual for more
information on this option.
In order to manage a switch, you must have access to one of the available
management methods. Telnet, SNMP, and IBM StorWatch Specialist require that the
switch be accessible using a network connection. The network connection can be
from the switch Ethernet port (out of band) or from fibre channel (in band). The
switch must be configured with an IP address to allow for the network connection.
Following this section, a detailed description is provided on how to ensure the
switch has a valid IP address that allows for network management. All other
hardware related information is contained in the IBM StorWatch Specialist hardware
reference manuals.
Before changing any of the factory default settings, become familiar with the
operations described in this chapter, including both the switch functions and
interactive characteristics.
There are several access methods for managing a switch. Table 20 summarizes the
management access methods available.
Note:
Switches can be accessed simultaneously from different connections. If this
happens changes from one connection may not be updated to the other, and
some may be lost. Make sure when connecting with simultaneous multiple
connections, that you do not overwrite the work of another connection.
