Chapter 1: Product description System management

• Read Only

• System Administrator

Read Only and System Administrator users are associated with fixed views allowing access to

the whole of the MIB, excluding the objects associated with SNMPv3 security. System

Administrators have read/write access as defined in the standard and proprietary MIBs.

Web-based management of SNMPv3 security allows an operator to define the security levels

and protocols for each of the security roles; all users with the same role share a common

selection of security level and protocols.

Web-based security configuration is re-initialized when any of the following occurs:

• All ODU configuration data is erased.

• The SNMP Engine ID Format has been changed.

• The SNMP Engine ID Format is Internet Address and the Internet Address has been

changed.

• The SNMP Engine ID Format is Text String and the text string has been changed.

• The SNMP Engine ID Format is MAC Address and configuration has been restored using a

file saved from a different unit.

• SNMPv3 Security Management is changed from MIB-based to web-based.

Additionally, all SNMP user accounts are disabled when the authentication protocol, the

privacy protocol, or the security level is changed.

Downgrade of the license key

A possible lockout condition exists if a user downgrades the PTP 700 license key so as to

disable the AES capability when SNMPv3 users are configured with AES privacy and VACM is

configured to require privacy. In this case, recovery is by either (a) restoring the correct license

key, or (b) using recovery mode to rest all configuration and entering new configuration.

Option (b) will cause default users and access configuration to be re-created.
