Synchronizing the Network
Network synchronization includes specification of primary, secondary, and tertiary clock sources. The
latter two sources serve as backups in case of clock failures. The cnfclksrc command specifies the
source of a clock and can remove a previously specified clock source. Multiple primary sources, multiple
secondary sources, and multiple tertiary sources are allowed.
Managing Jobs
Tip For information on the switch software commands listed in this section, see the full command
description in the Cisco WAN Switching Command Reference.
A job is a user-specified string of commands. A job can automatically run on a prearranged schedule or
on an event trigger. This section describes how to:
• Create a job
• Run a job
• Stop a job
• Display one or more jobs
• Edit a job
• Delete a job
• Create a job trigger
The system assigns a number to a new job. This job number identifies the job and is a required parameter
for most job control commands. When you create a new job, your privilege level is automatically saved
as the privilege level of the job. Use only commands that are available at your privilege level in your job
specification. For example, a user whose privilege level is 3 cannot include the addtrk command in a
job because addtrk requires a level 1 privilege. This privilege requirement also applies to other job
functions, such as running, editing, or stopping a job.
Tip Not all switch software commands can run as a part of a job. See the full command description in the
Cisco WAN Switching Command Reference to see which commands are allowed in a job.
Table 3-6 Switch Software Commands Used in IGX Clock Synchronization
Command Description
clrclkalm Clears an alarm associated with a clock source or path. The
cause of an alarm is usually a failed clock source or one that
is outside frequency limits. You must clear a clock alarm
before the corresponding clock source is usable.
cnfclksrc Specifies a primary, secondary, or tertiary clock source in a
network, or removes a clock source.
dspclksrcs Displays all the currently defined clock sources.
dspcurclk Displays the clock source that the node is currently using.
