Chapter 2. Accessing the switch
This chapter explains the types of connections that you can use to physically
access the switch. Once the connection is established, you will configure the IP
information (either through the terminal interface or through DHCP or BootP), and
then choose which user interface you want to use to manage it. Therefore, all
interfaces support configuring the switch and obtaining information from it, thus
providing greater flexibility in how you manage your switch.
Types of Connectivity
There are two connection methods used to physically access the switch:
v
Out-of-band connectivity, which provides access to the switch through the EIA
232 port.
v
In-band connectivity, which provides access to the switch from a remote station
using the Ethernet network
Table 10 outlines the user interfaces that are available depending on your method
of connection.
Table 10. Connection methods and available user interfaces
Type of Connection Available User Interface
Out-of-band Terminal interface via the EIA 232 port
(terminal directly attached, or remotely
attached to modem)
In-band
v
Terminal interface via Telnet
v
SNMP-based management interface
v
Web-based management interface
Out-of-band connection
Out-of-band connection lets you access your switch through the serial EIA 232 port.
It can be either through a locally attached PC running VT100 terminal emulation
software, or through a remotely attached PC running VT100 terminal emulation
software connected to a modem.
Locally attached terminal
To establish out-of-band connectivity using a locally attached terminal, make the
physical connections and set up using the following procedure:
1. Attach one end of a null-modem cable to the EIA 232 port of the switch as
shown in Figure 9 on page 20, and the other end to the COM port of your PC
(see “Appendix C. Cable Pinout Diagrams” on page 109).
