Setting The Synchronization Source - Avaya G430 Manual

Synchronization
The port ID parameter only applies if the source is a BRI module.
By setting the clock source to primary, normal failover occurs. The identity of the current
synchronization source is not stored in persistent storage. Persistent storage is used
to preserve the parameters set by this command.
Setting the source to secondary overrides normal failover, generates a trap, and
asserts a fault. Thus, it is only recommended to set the clock source to secondary
for testing purposes.

Setting the synchronization source

Procedure
To determine which reference source is the active source, use the set sync source
primary|secondary command.
If you choose secondary, the secondary source becomes active, and the primary
source goes on standby. In addition, fallback to the primary source does not occur even
when the primary source becomes available.
Result
If neither primary nor secondary sources are identified, the local clock becomes the active
source.
Example
The following example sets the MM710 media module located in slot 2 of the Branch Gateway
chassis as the primary clock synchronization source for the Branch Gateway.
set sync interface primary v2
set sync source primary
If the Branch Gateway includes a second MM710 media module, enter the following additional
command:
set sync interface secondary v3
set sync source secondary
If, for any reason, the primary MM710 media module cannot function as the clock
synchronization source, the system uses the MM710 media module located in slot 3 of the
Branch Gateway chassis as the clock synchronization source. If neither MM710 media module
can function as the clock synchronization source, the system defaults to the local clock running
on the chassis.
