The CTM server and managed nodes must be synchronized with the same date and time. If the CTM server and managed nodes do not have the same date and time, there might be inconsistencies in retrieving
3.11.1 Viewing Clocking Sources
CTM supports manual clock configuration. This configures both a primary and secondary clock source, which are distributed throughout the network. The secondary clock source takes over if the primary clock source fails. You can configure a network setup with one master clock source, and a secondary to ensure network clock stability.
On Cisco MGX 8850 (PXM45) switches, clock source configuration is done on a PXM45 card, and clock sourcing information is passed to other nodes over AXSM lines.
Clock synchronization is done directly on the Cisco MGX 8880 using the CLI.
These topics are used to manage and configure clocking sources:
