Configuring Timing References
Listed below is an example to configure timing reference parameters.
Example:
config>system# sync-if-timing
config>system>sync-if-timing# begin
config>system>sync-if-timing# ref1
config>system>sync-if-timing>ref1# source-port 1/1/1
config>system>sync-if-timing>ref1# no shutdown
config>system>sync-if-timing>ref1# exit
config>system>sync-if-timing# ref2
config>system>sync-if-timing>ref2# source-port 1/1/2
config>system>sync-if-timing>ref2# no shutdown
config>system>sync-if-timing>ref2# exit
config>system>sync-if-timing>commit
The following displays the timing reference parameters:
*7210-SAS>config>system>sync-if-timing#info detail
----------------------------------------------
ref-order ref1 ref2
ref1
source-port 1/1/1
no shutdown
exit
ref2
source-port 1/1/2
no shutdown
exit
no revert

Using the Revert Command
If the current reference goes offline or becomes unstable the revert command allows the clock to
revert to a higher-priority reference.
When revert is switching enabled a valid timing reference of the highest priority is used. If a
reference with a higher priority becomes valid, a reference switch over to that reference is
initiated. If a failure on the current reference occurs, the next highest reference takes over.
If non-revertive switching is enabled, the valid active reference always remains selected even if a
higher priority reference becomes available. If the active reference becomes invalid, a reference
switch over to a valid reference with the highest priority is initiated. The failed reference is
eligible for selection once it becomes operational.
CLI Syntax: config>system>sync-if-timing
