Accessing the User Interface 39
Accessing the User
Interface
You can access the user interface in the following ways:
■
From a PC or workstation, to a Layer 3 Module IP address, using
Telnet.
■
Through an SNMP-based network management application such as
the 3Com Transcend Network Control Services suite of network
management tools.
Using an IP
Management
Interface
An IP management interface allows you to manage the system through
an Ethernet port. After you configure an IP management interface with a
unique IP address, you can also use Telnet to connect remotely to the user
interface using the TCP/IP protocol from a host computer, or you can
reach the SNMP agent from a network management application.
When you enter the user interface, the system prompts you for an access
level and password:
Select access level (read, write, administer):
Password:
The passwords are stored in nonvolatile memory. You must enter the
password correctly before you can continue.
Levels of User
Access
The Layer 3 Module supports three password levels so that the network
administrator can provide different levels of access for different users.
Table 12 describes these access levels.
