Runts and CRC errors increment Cisco 2960G-24TL

Unanswered Question

Hi,

Currently I'm facing some network troubleshooting difficulties. Currently I'm connecting 2 units of Cisco 2960G-24TL to a few controllers from Yokogawa. The usage is to transmit their safety system data monitoring/controlling via Yokogawa's proprietary protocol called VNET IP (http://www.yokogawa.com/dcs/products/vnet-ip/dcs-vnetip-02-en.htm).

Yokogawa controller each has 2 cards and each individual card has 2 ports. Yokogawa redundant system consist of 2 BUS lines - BUS1 and BUS2 (both with different IPs). BUS1 will act as primary link and BUS2 as redundant link (in case on one controller's is down, another one will take over).

The problem is there's some problems on the network status of the overall Yokogawa's data flow as from time to time (non-periodical and inconsistent time frame), there'll be some data loss due to CRC errors increment. I've gone thorough the link ( http://supportwiki.cisco.com/ViewWiki/index.php/Runts_and_CRC_errors_increment_in_the_show_interface_command_output_on_a_Cisco_IOS-based_switch,_or_FCS_errors_and_runts_increment_in_the_show_port_command_output_on_a_CatOS_based_switch_due_to_a_duplex_mismatch ) and tried all the suggested solutions, but the result still persists.

Can you please help to advise what might be the possible cause of the problems, what else can I do to troubleshoot?

I have this problem too.
