4 Open the Telnet session by specifying the IP address of the Switch. Check
the documentation supplied with the Telnet facility if you are unsure how
to do this.
Any network management application running the Simple Network
Management Protocol (SNMP) can manage a Switch if:
The correct Management Information Bases (MIBs) are installed on the
management workstation.
The management workstation is connected to the Switch using a port
in VLAN 1 (the Default VLAN). By default, all ports on the Switch are in
VLAN 1.
For information about using an SNMP network management application
to manage a Switch, see the documentation supplied with the software.
To manage your Switch using an SNMP network management
application, you need to specify SNMP community strings for the users
defined on the Switch. You can do this using the command line interface
— refer to the command line interface section of the "Management
Interface Reference Guide" on the CD-ROM that is supplied with the
Switch.
To manage a Switch over the network, the Switch must be correctly
configured with the following IP information:
An IP address — for more information, see
A subnet mask — for more information, see
Subnet Mask"
A default IP gateway — for more information, see
on page 32.
If you are uncertain about what IP addresses to assign your equipment,
contact your network administrator.
To operate correctly, each device on your network (for example a hub or
management station) 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 '192.168.100.8'.
