RADIUS Authentication
and Accounting
The RADIUS Authentication/Accounting screen lets you define the servers to be
used for RADIUS authentication and accounting functions. You must set up
authentication and accounting parameters if you plan to enable any type of
RADIUS authentication as configured on the Encryption page. These include
primary authentication and dynamic key exchange servers, along with primary and
secondary accounting servers as required. If you enter an invalid IP address for any
of the servers, an error message is displayed.
Once an accounting server is set up, you can turn accounting on or off from this
screen. If the servers are set up and accounting is turned off, the settings remain
saved.
Management
The Management pages let you configure the access point for use with third-party
SNMP management programs and specify the TFTP server you will use for various
administrative functions, including backing up and restoring access point settings
and setting up the access point system log.
SNMP Management
The SNMP Management screen lets you set up the configuration for using the
access point in conjunction with third-party SNMP management programs. From
this page, you can:
■
Modify the Read Only or Read Write community names. Activation of either
Modify button displays the corresponding page where the community names
can be set.
■
Identify one or two host machines to receive SNMP traps.
■
Identify which traps to send to the trap host or hosts.
TFTP Setup
A TFTP server must be set up in order to perform firmware updates, backups, and
restores. The TFTP Setup screen identifies the TFTP server that will be used. If you
do not have a TFTP server, you can install the one shipped with the access point.
Use the 3Com Administrator Utilities CD (Tools and Utilities options) to start the
3CDAEMON and install the TFTP Server Tool.
You must supply the IP address of the TFTP server computer. The default TFTP client
port number is 69, the TCP/UDP port number that is most commonly used for
TFTP, although you can change this to a different port number if required.
System Log Setup
The System Log screen lets you set up one or two computers for saving log files
and to enable or disable logging. Log files are not viewable through the
Configuration Management System or the access point, and so must be accessed
from the host computer.
By default, logging is off. If you turn on logging, you must specify at least one
host. You must also enter the TCP/UDP port number that will be used for sending
the log information from the access point to the host systems using syslog. By
default, the port is set to 514, the TCP/UDP port number that is most commonly
used for syslog, although you can change this to a different port number if
required.
When logging is enabled, log information is saved until the function is turned off.
