Cisco Systems BC-109 Monitor and Maintain the SRB Network, Report Spurious Frame-Copied Errors

Monitor and Maintain the SRB Network

Report Spurious Frame-Copied Errors

An IBM 3174 cluster controller can be configured to report frame-copied errors to IBM LAN Network Manager software. These errors indicate that another host is responding to the MAC address of the 3174 cluster controller. Both the 3174 cluster controller and the IBM LAN Network Manager software can be configured to ignore frame-copied errors.
