SNMP (Simple Network Management Protocol)
Used in network management systems to monitor network-attached devices
(routers, servers, switches, projectors, etc) for conditions that warrant
administrative attention. SNMP exposes management data in the form of
variables on the managed systems, which describe the system configuration.
These variables can then be queried (set to ReadOnly) and sometimes set (set
to ReadWrite) by managing applications.
Mode: Set to Off when you want to disable the SNMP network service.
ReadOnly: Set to ReadOnly
network service for queries only.
ReadWrite: Set to ReadWrite
network service for both queries and commands.

Using E20
Community
Community. SNMP Community names are used to authenticate SNMP
requests. SNMP requests must have a 'password' (case sensitive)
in order to receive a response from the SNMP Agent in the codec.
The default password is "public". If you have the Cisco TelePresence
Management Suite (TMS) you must make sure the same SNMP
Community is configured there too.
password is case sensitive.
System
System Contact.
System
System Location.
Host IP
then be sent to the host listed.
The system's SNMP Agent responds to requests from SNMP Managers
(a PC program etc.). SNMP Traps are generated by the SNMP Agent to
inform the SNMP Manager about important events. Can be used to send
event created messages to the SNMP agent about different events like:
system reboot, system dialing, system disconnecting, MCU call, packet
loss etc. Traps can be sent to multiple SNMP Trap Hosts.
SIP
Determines whether the system should be able to place and receive SIP calls.
to
On: Set to On to enable the possibility to place and receive SIP calls.
This is the default setting.
HTTPS
Off: Set to Off to disable the possibility to place and receive SIP calls.
NTP (Network Time Protocol)
The Network Time Protocol (NTP) is used to synchronize the time of the system
with a reference time server. The time server will subsequently be queried
every 24th hour for time updates. The time will be displayed on the top of the
screen. The system will use the time to timestamp messages transmitted to
Gatekeepers or Border Controllers requiring H.235 authentication. The system
will use the time to timestamp messages transmitted to Gatekeepers or Border
Controllers that requires H.235 authentication. It is also used for timestamping
Placed Calls, Missed Calls and Received Calls.
Auto: The system will use the NTP server, by which address is supplied
from the DHCP server in the network. If no DHCP server is used, or the
DHCP server does not provide the system with a NTP server address,
the system will use the static defined NTP server address specified by
the user.
