Using Telnet
Any Telnet facility that emulates a VT100 terminal
should be able to communicate with the Switch
over a TCP/IP network. Up to three active Telnet ses-
sions can access the Switch concurrently. If a con-
nection to a Telnet session is lost inadvertently, the
connection is closed by the Switch after 2–3 min-
utes of inactivity.
Before you can start a Telnet session you must set
up the IP parameters described in “
Switch Manage-
ment Setup” on page 3-9.
To open the Telnet session, you must specify the IP
address of the device you want to manage. Check
the user manual supplied with the Telnet facility if
you are unsure how to do this.
Once the connection is established, the main banner
of the VT100 management interface is displayed
and you can log on.
Managing Over The Network
Any Network Manager running the Simple Network
Management Protocol (SNMP) can manage the
Switch, provided the MIB (Management Informa-
tion Base) is installed correctly on the management
workstation.
Each Network Manager provides its own user inter-
face to the management facilities. 3Com's
Transcend
®
range of Network Managers all have
facilities for managing the Switch.
The Switch supports SNMP over both IP and IPX
protocols.
IP Addresses
If you are uncertain about IP addresses that may be
assigned to your devices, contact your network
administrator first.
To operate correctly, each device on your network
must have a unique IP address. IP addresses have
the format n.n.n.n where n is a decimal number
between 0 and 255. An example IP address is:
191.128.40.120
The IP address can be split into two parts:
■
The first part (191.128 in the example) identifies
the network on which the device resides.
■
The second part (40.120 in the example) identi-
fies the device within the network.
