144 About the Nortel Ethernet Routing Switch 4500 Series
When SNTP is enabled (the default value is Disabled), the system
synchronizes with the configured NTP server at boot-up (after network
connectivity is established) and at user-configurable periods thereafter (the
default synchronization interval is 24 hours). The synchronization also can
happen upon manual request.
The SNTP feature supports both primary and secondary NTP servers. It
attempts to contact the secondary NTP server only if the primary NTP
server is unresponsive. When a server connection fails, SNTP retries for a
maximum of three times, with 5 minutes between each retry.

Ping enhancement

Using the CLI you can specify additional ping parameters, including the
number of ICMP packets to be sent, the packet size, the interval between
packets, and the timeout. You can also set ping to continuous, or you can
set a debug flag to obtain extra debug information.
