with the LAN1 port, use the STATUS button on the front panel to obtain the new IP address.
Furthermore, if it occurs to a network port servicing NTP requests, NTP clients will no longer
be able to get a response from that port. In that case, the NTP clients would have to use an
alternate NTP source or become unsynchronized. For this reason, Microsemi recommends
using static IP addresses, only using DHCP for convenience during temporary installations.
IP Version:
n IPv4: The port uses IPv4 exclusively. (Static or DHCP)
n IPv6: The port uses IPv6 exclusively. The user must enter a static IPv6 address.
IP Address: The port's IPv4 address (e.g., "192.168.0.100") or IPv6 address(es) with
scope (e.g., fe80::2a0:6dff:fe00:10).
Mask: The port's IPv4 subnet mask (e.g., "255.255.255.0"). With IPv6, the mask is the
length of the prefix.defined in CIDR format (Classless Inter Domain Routing). Typically, the
IPv6 mask is 64.
Note: The SyncServer does not support masks on IPv6 gateway entry. While the user inter-
face will accept/display a user entered mask, such as “/64” for the IPv6 gateway, the under-
lying software checks for the entered mask and removes it, before sending the unmasked
IPv6 gateway address down to the lower level Linux system components to configure the net-
work interface.
Gateway: The port's IPv4 or IPv6 gateway (e.g., "192.168.0.1"). This is an optional con-
figuration parameter.
Management: Reserved for future use.
Redundant: Bonds LAN3 to LAN2 as virtual device with a single network address.
n Active: The Active port handles network traffic. LAN2 is "Active" by default.
n Backup: The Backup port handles network traffic if the connection to the Active port fails.
LAN3 is the "Backup" port by default.
If the connection to LAN2 fails, LAN2 becomes backup and LAN3 becomes active. After
repairing the connection, the user can manually reconfigure LAN2 as the Active port:
1. In the "LAN2 Configuration" window, select the "Redundant" checkbox, select "Active",
and then click the APPLY button.
2. On the NETWORK - Ethernet page, click the APPLY button.
To release a redundant bond, deselect the "Redundant" checkbox and apply the changes. If
the bond doesn't release, reboot the SyncServer.
Allowed Access: Restricts the LAN port to access by specified IP addresses or address
ranges. If the user leaves this field blank, the LAN port accepts connections from any IP
address. Allowed Access applies to all forms of network traffic, including NTP and HTTP con-
nections. Reconfiguring the IP address of the LAN port erases the Allowed Access list.
The user can specify address ranges by setting the IP address followed by the mask prefix
length, as described RFC 1518 and RFC 1519 for Classless Inter-domain Routing. The
mask prefix length specifies the number of masked bits starting from the left-most pos-
ition. For example, to allow access from the network represented by 192.168.0.0,
