Chapter 5 Advanced Configuration Statistics > RMON Statistics The RMON Statistics screen contains fields for viewing information about device utilization and errors that occurred on the device. Statistics > RMON Statistics Interface Indicates the device for which statistics are displayed. The possible field values are: •• Port Defines the specific port for which RMON statistics are displayed. •• LAG Defines the specific LAG for which RMON statistics are displayed. Refresh Rate Defines the amount of time that passes before the interface statistics are refreshed. The possible field values are: •• No Refresh Indicates that the RMON statistics are not refreshed. •• 15 Sec Indicates that the RMON statistics are refreshed every 15 seconds. •• 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 Frame Check Sequence (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. WebView Switches 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 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 20-150 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. Refresh Now button Use this option to refresh the statistics that are displayed on the page. 29
