Some time ago it was considered acceptable, even normal, to have a certain level of errors on an Ethernet port.Times have changed.These events are caused by problems in the system configuration or cabling, and will absolutely impact the performance of business applications, voice systems, and video services.When a packet is dropped, if the transport layer supports retransmissions, the missing segment will need to be re-sent by the originating station or server.

Retransmissions take time to send.If these happen at the beginning of a TCP connection, it can take up to three full seconds for the sending stack to flag that a packet was lost.This time can dramatically reduce the performance of critical applications

How can we find these errors?Active SNMP-based tools make this search much easier.This 10 minute video can show you how:
