used to identify this SNMP agent
to the SNMP manager.

Authentication Enables or disables SNMPv3
mode authentication.

5.
Password The password used to encrypt
authentication credentials.
Privacy settings (only applicable to SNMPv3)
Privacy mode Enables or disables SNMPv3
encryption.
Type The security model used to
encrypt messages.
DES: Data Encryption Standard
56-bit encryption.
AES: Advanced Encryption
Standard 128-bit encryption.
Password The password used to encrypt
messages.
The VCS does not support SNMP traps or SNMP sets, therefore it cannot be managed via SNMP.
Note: SNMP is disabled by default, because of the potentially sensitive nature of the information
involved. Do not enable SNMP on a VCS on the public internet or in any other environment where you
do not want to expose internal system information.

Configuring time zone and NTP server settings

time zone.
NTP server
The NTP server is a remote server with which the VCS synchronizes in order to ensure its time setting
is accurate. The NTP server provides the VCS with UTC time. Accurate timestamps play an
important part in H.323 authentication, helping to guard against replay attacks. For this reason, if you
are using authentication in a deployment that includes H.323, both the VCS and the endpoints must
use an NTP server to synchronize their system time.
