96 Chapter 6 Configuring RMON using Device Manager
Field Description
UndersizePk
ts The number of packets received during the sampling interval
that were less than 64 octets long (including FCS octets, but
not framing bits).
OversizePkt
sThe number of packets received during the sampling interval
that were longer than 1518 octets (including FCS octets, but
not framing bits) and were otherwise well-formed.
Fragments The number of packets received during the sampling interval
that were less than 64 octets long (including FCS octets, but
not framing bits) that had a bad FCS with either an integral
number of octets (FCS Error) or a non-integral number of octets
(Alignment Error).
Collisions The best estimate of the number of collisions on an Ethernet
segment during a sampling interval.
Enabling Ethernet statistics gathering
Youcan use RMON to gather Ethernet statistics.
To gather Ethernet statistics:
Step Action
1From the Device Manager main menu, choose RMon > Control.
The RmonControl dialog box opens with the History tab displayed.
2Click the Ether Stats tab.
The Ether Stats tab opens (Figure 36 "RmonControl dialog box --
Ether Stats tab" (page 96)).
