Dear Mr Tim, Well ...Let me introduce myself first..I am Dheerendra from India working for an ISP. The answer to your query regarding what is meant by serial resets and how does it occur can be described here Interface Resets: Number of times an interface has been completely reset. This can happen if packets queued for transmission were not sent within several seconds' time. On a serial line, this can be caused by a malfunctioning modem that is not supplying the transmit clock signal, or by a cable problem. If the system notices that the carrier detect line of a serial interface is up but the line protocol is down, it periodically resets the interface in an effort to restart it. Interface resets can also occur when an interface is looped back or shut down regds dheeru Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=20363&t=20363 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
