33.2.2 Disabling Secure Operation Mode
This section describes how to disable the Secure Operaiton mode.
Note: The following procedures apply to SC Rev.1 boards (using the Solaris OS)
only. Secure Mode is automatically enabled for SC Rev.2 (using the Linux OS)
boards and cannot be disabled .
To disable Secure Operation Mode:
Repeat the same steps as described in 'Enabling Secure Operation Mode ' on
page
307above; however at the Enable Security prompt, choose 0 and press
Enter.
33.3 Secure Access to the SNMP Management
Interface
The SNMP management interface is used by EMS server and/or standards-compliant
3
rd
party SNMP managers to perform most of the Mediant 8000 management,
configuration and status monitoring tasks. For detailed description, see 'SNMP
Management Interface' on page 170.
The Mediant 8000 supports the following SNMP operational modes:
SNMPv2 – a simple default management mode widely deployed in many closed
networks; has a relatively weak security model based on the plain-text read and
write community strings and therefore is a security threat for systems connected
to the public networks (e.g. Internet).
SNMPv2 + IPSEC – a secure version of the SNMPv2 management mode;
communication between the Media Gateway and the EMS server is secured via
IPSEC/IKE protocol with a pre-shared key; any additional 3
rd
party SNMP
manager must have valid IPSEC/IKE association to be able to access Media
Gateway’s SNMP interface.
SNMPv3 – the latest and secure version of the SNMP management protocol; use
of IPSEC/IKE with SNMPv3 is not recommended, because SNMPv3 has its own
authentication and encryption mechanisms.
For secure operation of the Mediant 8000 choose SNMPv2 + IPSEC or SNMPv3
management modes.
See 'Configuring Connectivity between Media Gateway and EMS Server' on page
171 for detailed description on how to configure SNMP management mode and
establish connectivity with EMS server.
