NOTE: The EUM factory default settings have ports 137, 138, 139, and
1512 filtered out for both TCP and UDP, to prevent Network
Neighborhood from seeing other end users’ computers.
7.7 Configuring the SNTP/UTC Time Clock
To configure the SNTP/UTC clock
• Add an NTP server, if the one to which you want the CCU to synchronize has not
already been added. You may want to delete the default NTP servers, to force the
CCU to synchronize to the server you are adding.
• Set the SNTP client resynchronization period. The factory default setting is
3600seconds, and WaveRider recommends not changing this default setting.
• Set the SNTP client retry period. The factory default setting is 30seconds, and
WaveRider recommends not changing this default setting.
• Enable the SNTP client, to force the CCU to synchronize to an NTP server.
• Enable the SNTP relay, if you want the EUMs to be synchronized to the CCU.
To add an NTP server
1. Type time add <aaa.bbb.ccc.ddd> and press Enter.
• <aaa.bbb.ccc.ddd> is the IP address of the NTP server you are adding.
2. Type save or commit and press Enter.
CAUTION: The CCU NTP server list must always contain the
local host, which is 127.0.0.1. This entry is required for the case
where the CCU loses connectivity with the other NTP servers in
the list.
NOTE: Up to four NTP servers can be configured in the CCU, which is
shipped from the factory configured factory-default NTP servers.
To add an NTP server, you must delete one of the four defaults.
