Use the Rmon tab of the Graph Port dialog box to view RMON statistics for the selected port.
The following table describes the parts of the Rmon tab.
Octets
Shows the total number of octets of data (including those in bad packets) received on the network (excluding framing bits but including FCS octets). You can use this object as a reasonable estimate of Ethernet utilization. For greater precision, sample the etherStatsPkts and etherStatsOctets objects before and after a common interval.
Pkts
Shows the total number of packets (including bad packets, broadcast packets, and multicast packets) received.
BroadcastPkts
Shows the total number of good packets received that were directed to the broadcast address. Note that this does not include multicast packets.
MulticastPkts
Shows the total number of good packets received that were directed to a multicast address. Note that this number does not include packets directed to the broadcast address.
CRCAlignErrors
Shows the total number of packets received that had a length (excluding framing bits, but including FCS octets) of between 64 and 1518 octets, inclusive, but had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a nonintegral number of octets (Alignment Error).
UndersizePkts
Shows the total number of packets received that were less than 64 octets long (excluding framing bits but including FCS octets) and were otherwise well formed.
OversizePkts
Shows the total number of packets received that were longer than 1518 octets (excluding framing bits but including FCS octets) and were otherwise well formed.
Fragments
Shows the total number of packets received that were less than 64 octets in length (excluding framing bits but including FCS octets) and had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a nonintegral number of octets (Alignment Error). It is entirely normal for etherStatsFragments to increment because it counts both runts (which are normal occurrences due to collisions) and noise hits.
Collisions
Shows the best estimate of the total number of collisions on this Ethernet segment.
Jabbers
Shows the total number of packets received that were longer than 1518 octets (excluding framing bits, but including FCS octets), and had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral number of octets (Alignment Error). Jabber is defined as the condition where any packet exceeds 20 ms. The allowed range to detect jabber is between 20 ms and 150 ms.
1..64
Shows the total number of packets (including bad packets) received that were less than or equal to 64 octets in length (excluding framing bits but including FCS octets).
65..127
Shows the total number of packets (including bad packets) received that were greater than 64 octets in length (excluding framing bits but including FCS octets).
128..255
Shows the total number of packets (including bad packets) received that were greater than 127 octets in length (excluding framing bits but including FCS octets).
256..511
Shows the total number of packets (including bad packets) received that were greater than 255 octets in length (excluding framing bits but including FCSoctets).
512..1023
Shows the total number of packets (including bad packets) received that were greater than 511 octets in length (excluding framing bits but including FCS octets).
1024..1518
Shows the total number of packets (including bad packets) received that were greater than 1023 octets in length (excluding framing bits but including FCS octets).
