SNTP
The ipAddressConfigSntp group provides the configuration necessary for contacting a NTP/SNTP server.
If you are using a NTP or SNTP server (see “Chapter 14 -
SNTP Settings” on page 157 for more details), the
DHCP server already has options that can be set to provide time server addresses, and the order in which
clients use them to attempt to discover servers.
The Mediatrix 4100 uses Option 42 to specify the IP address corresponding to the server that provides NTP/
SNTP (RFC 1769).
 To select the SNTP configuration source:
1. In the ipAddressConfig folder, locate the sntpSelectConfigSource variable (under the
ipAddressConfigSntp group).
2. Set this variable to either static or dhcp.
ETH2 Connector Static IP Address
You can use the ETH2 connector of the Mediatrix 4100 with the network card of a computer. You could then
use this computer to directly access the unit via its LAN interface.
This section describes how to set the static IP address of the ETH2 connector and use this LAN static IP
address according to the VLAN substitution or always enabled configuration.
 To set the ETH2 connector static IP address:
1. In the ipRoutingMIB, set the lanStaticAddressActivation variable to one of the following values:
In the Unit Manager Network Administration Manual, refer to chapter Administration Parameters, section
SNTP.
