600 CHAPTER 14: BULK CONFIGURATION
There is a security risk associated with configuring RADIUS secrets on the
devices over the network because the SNMP protocol that 3Com
Network Director uses to configure the devices is unencrypted. It is
possible that a user of the network could deliberately intercept the
packets sent out during the bulk configuration operation and determine
from them the RADIUS secret used. This risk can be reduced by
scheduling bulk configuration of RADIUS secrets to take place out of
office hours, or eliminate the risk by configuring the devices individually
using a console connection.
The RADIUS Servers feature places restrictions on the values that can be
set for the following parameters:
