remote access to the network using Telnet, Web browser, and SNMP.
Other areas include multiple levels of encryption and MD5-level
security for HTTP connections. The
Security Configuration Menu
( Figure 3-29 ) contains all of the settings related to these functions.
NOTE:
Security enhancements in entraNET 2.3.0 firmware
necessitate that encryption
must be turned
OFF
prior to
upgrading entraNET Remote radios with the new firmware.
Failure to turn encryption off results in loss of communication
between an AP and entraNET Remote radios. Once the
firmware upgrade is complete, you can re-enable encryption.
Additionally, any changes to encryption settings should be
made first at all Remote radios, then at the AP. This prevents a
loss of communication between the AP and Remote radios due
to security mismatches. Communication loss requires a
personal visit to each affected remote site, where restoration
can be performed at the Remote itself (see
CHAPTER 4
REMOTE RADIO MANAGEMENT, beginning on Page 99 ).
3.7.1 Security Configuration Menu
The Security Configuration Menu ( Figure 3-29 ) allows settings of
several parameters related to network access, user credentials, and
encryption. A review of each item on the menu is important to
safeguarding your network from unauthorized access. Review these
settings occasionally to make sure they are applicable to the current state
of your network.
