Viewing G700 Sync Sources

The following tables illustrate example locations of the clock synchronization sources:

Note: Unless otherwise indicated, the following commands issue from the G700 MGP CLI.

Table 50. mgp-001-1(configure)# show sync timing
SOURCE	MM	STATUS	FAILURE
Primary		Not Configured
Secondary		Not Configured
Local	v0	Active	None
Comment: No failures, SIG GREEN on and ACT on when trunk is seized

Table 51. mgp-001-1(configure)# set sync interface primary v4
mgp-001-1(configure)# show sync timing
SOURCE	MM	STATUS	FAILURE
Primary	V4	Locked Out	None
Secondary		Not Configured
Local	V0	Active	None
Comment: No failures, Sig is green and ACT On 2.8s off 0.2s Note that the MM710 in slot 4 has been declared to be the primary sync source but it is not active until the next command is issued

Table 52. mgp-001-1(configure)# set sync source primary
mgp-001-1(configure)# show sync timing
SOURCE	MM	STATUS	FAILURE
Primary	V4	Active	None
Secondary		Not Configured
Local	V0	Standby	None
Comment: The ACT LED does not change its behavior.

Note: The following command is issued from the SAT CLI, and not from the MGP CLI.

To test for slippage, from the SAT, issue the command:

test mo logical 4255 physical 1v4 test 144

The results from the above command are shown in Table 53:

Table 53. TEST RESULTS
Port	Maintenance Name	Alt. Name	Test No. Result	Error Code
001V4	MG-DS1	144	PASS
Command successfully completed

If a secondary is similarly provisioned:

Table 54. mgp-001-1(configure)# set sync interface secondary v3
mgp-001-1(configure)# show sync timing
SOURCE	MM	STATUS	FAILURE
Primary	V4	Active	None
Secondary	V3	Standby	None
Local	V0	Standby	None

To activate the secondary, the following is similarly done:

Table 55. mgp-001-1(configure)# set sync source secondary
mgp-001-1(configure)# show sync timing
SOURCE	MM	STATUS	FAILURE
Primary	V4	Locked Out	None
Secondary	V3	Active	None
Local	V0	Standby	None
Note: The system uses one clock at a time only: therefore only the secondary is active and the primary is locked out.

To activate local the following is done:

Table 56. mgp-001-1(configure)# set sync source local
mgp-001-1(configure)# show sync timing
SOURCE	MM	STATUS	FAILURE
Primary	V4	Locked Out	None
Secondary	V3	Locked Out	None
Local	V0	Active	None

To reactivate the primary, the following is done:

Table 57. mgp-001-1(configure)# set sync source primary
mgp-001-1(configure)# show sync timing
SOURCE	MM	STATUS	FAILURE
Primary	V4	Active	None
Secondary	V3	Standby	None
Local	V0	Standby	None
Note that secondary and local are standby because they are provisioned as fail overs.

If the T1 physical connection were removed, then the secondary becomes active and the primary reports a failure.

Table 58. mgp-001-1(configure)# show sync timing
SOURCE	MM	STATUS	FAILURE
Primary	V4	Standby	Out of Lock
Secondary	V3	Active	None
Local	V0	Standby	None
Note that primary and local are standby because they are provisioned as fail overs.
