Chapter 5 Advanced Configuration •• 30 Sec Indicates that the RMON statistics are refreshed every 30 seconds. •• 60 Sec Indicates that the RMON statistics are refreshed every 60 seconds. Drop Events Displays the number of dropped events that have occurred on the interface since the device was last refreshed. Received Bytes (Octets) Displays the number of octets received on the interface since the device was last refreshed. This number includes bad packets and FCS octets, but excludes framing bits. Received Packets Displays the number of packets received on the interface, including bad packets, Multicast and broadcast packets, since the device was last refreshed. Broadcast Packets Received Displays the number of good broadcast packets received on the interface since the device was last refreshed. This number does not include Multicast packets. Multicast Packets Received Displays the number of good Multicast packets received on the interface since the device was last refreshed. CRC & Align Errors Displays the number of CRC and Align errors that have occurred on the interface since the device was last refreshed. Undersize Packets Displays the number of undersized packets (less than 64 octets) received on the interface since the device was last refreshed. Oversize Packets Displays the number of oversized packets (over 1518 octets) received on the interface since the device was last refreshed. Fragments Displays the number of fragments (packets with less than 64 octets, excluding framing bits, but including FCS octets) received on the interface since the device was last refreshed. Jabbers Displays the total number of received packets that were longer than 1518 octets. This number excludes frame bits, but includes FCS octets that had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral octet (Alignment Error) number. The field range to detect jabbers is between 20 ms and 150 ms. Collisions Displays the number of collisions received on the interface since the device was last refreshed. Frames of xx Bytes Number of xx-byte frames received on the interface since the device was last refreshed. Clear Counters button This option will reset all of the statistic counts. 8-Port 10/100/1000 Gigabit Switch with Webview Refresh Now button Use this option to refresh the statistics. Statistics > RMON History The RMON History screen contains information about samples of data taken from ports. For example, the samples may include interface definitions or polling periods. Statistics > RMON History The RMON History screen is divided into RMON History and Log Table. Source Interface Displays the interface from which the history samples were taken. The possible field values are: •• Port Specifies the port from which the RMON information was taken. •• LAG Specifies the port from which the RMON information was taken. Sampling Interval Indicates (in seconds) the time that samplings are taken from the ports. The field range is 1‑3600. The default is 1800 seconds (equal to 30 minutes). Max No. of Samples to Keep Indicates the number of samples to save. Owner Displays the RMON station or user that requested the RMON information. The field range is 0-20 characters. The Add to List button adds the configured RMON sampling to the Log Table at the bottom of the screen. Log Table Sampling Requested Displays the number of samples to be saved. The field range is 1-65535. The default value is 50. 26
