Module resets and user receives the %SYS-3-MOD_PORTINTFINSYNC:Port Interface in sync for Module error message in Catalyst 6500 Series Switches that run CatOS software

Core issue

This message confirms that the module booting up has synchronized the onboard ASICs that handle the transfer of packets between the backplane and the network ports. [dec] is the module number.

The module reset can occur at unpredictable times or this may be a one time issue.

This problem is identified in Cisco bug ID CSCeb35612.


This is an informational message and does not affect any system performance.

If the reboot occurs several times, then upgrade the Cisco Catalyst OS (CatOS) Software on the switch to the latest maintenance release in order to resolve this problem. The software can be downloaded from Catalyst 6500/6000 CatOS System Software.

For more information, refer to the Troubleshoot WS-X6348 Module Silent Reloads section of Troubleshooting Catalyst 6500/6000 Series Switches Running CatOS on the Supervisor Engine and Cisco IOS on the MSFC.

Additional details can be found in article Module WS-X6348-RJ-45 resets frequently with the "%SYS-5-MOD_OK: Module [dec] is online" error message in a Catalyst 6000 switch that runs CatOS version.
