12.2.3.2.2 Network Interfaces and System Monitoring
Status monitoring of the system and network interfaces can be done via the standard MIB-
II (iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2(1)). The following table shows some of
the information elements available via MIB-II:

12.2.3.3 Security Concerns and Measures
Since SNMP allows write-access to configuration parameters, it is important to protect this
interface. The following security measures are available:
 A community string (password) can be defined for read-only access and for read/write
access.
 It is possible to limit access to SNMP to a trusted peer (single IP address or a range of
addresses).
 SNMPv3 provides an significant security improvement over SNMPv1/2. Version 2.8.0
will support SNMPv3 and will allow the service provider to configure SNMPv3 security
parameters.
 SNMP traffic can be allowed over an IPSec secured connection – check availability
with AudioCodes.
