Configuration Guide
Description Commands in this context configure the system time zone and time synchronization
parameters.
Network Time Protocol Commands
ntp
Syntax [no] ntp
Context config>system>time
Platforms Supported on all 7210 SAS platforms as described in this document, including platforms
configured in the access-uplink operating mode
Description Commands in this context configure Network Time Protocol (NTP) and its operation. This
protocol defines a method to accurately distribute and maintain time for network elements.
Furthermore this capability allows for the synchronization of clocks between the various
network elements.
The no form of this command stops the execution of NTP and removes its configuration.
authentication-check
Syntax [no] authentication-check
Context config>system>time>ntp
Platforms Supported on all 7210 SAS platforms as described in this document
Description This command provides the option to skip the rejection of NTP PDUs that do not match the
authentication key ID, type or key requirements. The default behavior when authentication is
configured is to reject all NTP protocol PDUs that have a mismatch in either the
authentication key ID, type or key.
When authentication-check is enabled, NTP PDUs are authenticated on receipt. However,
mismatches cause a counter to be increased, one counter for type and one for key ID, one
for type, value mismatches. These counters are visible in a show command.
The no form of this command allows authentication mismatches to be accepted; the counters
however are maintained.
Default authentication-check — rejects authentication mismatches
