The NE MAC Address/Bridge Address value is displayed in the NE MAC Address/

22.2.9 SNMP Mode
The 9500 MPR supports access from SNMP managers implementing both SNMPv2/
v1 and SNMPv3 protocols. The supported SNMP operating modes are the following:
• SNMPv2: This is the default mode. Only SNMPv2/v1 managers are allowed
access to the NE for both reading and writing.
• SNMPv3: Only SNMPv3 managers are allowed access to the NE.
SNMPv3 addresses security problems by adding two new features on top of the
existing SNMPv1 and SNMPv2 network management protocols:
• Authentication using hashing and time stamps.
• Confidentiality using encryption.
SNMPv3 is based on the following:
• The User based Security Model (USM), which provides strong user
authentication, data integrity, privacy (encryption) and time stamp management
(timeliness),
• The View base Access Control Model (VACM), which provides a mechanism for
managing what information is available to users.
Authentication is provided using the HMAC-MD5-96 standard authentication
protocol.
The SNMP operating mode is stored in permanent memory on a Flash card.
Caution: Changing the SNMP mode requires the NE to restart in the new mode.
Caution: When the NE has been configured to operate in SNMPv3 mode, the database
must be cleared for the NE to be returned to SNMPv2 mode.
