Usage Guidelines

After you configure Ethernet statistics using the rmon statistics command, the system collects packet statistics on Ethernet interfaces. The command output includes communication information generated since statistics function is enabled. The command output helps you locate faults.

When the device restarts, all statistics are cleared.

**Table 1** Description of the display rmon statistics command output
Item	Description
Statistics entry entry-number owned by owner is status.	The current status of the event entry entry-number created by owner is status. entry-number: Ethernet statistics entry, corresponding to the etherStatsIndex object in etherStatsTable. owner: creator of the entry, corresponding to the etherStatsOwner object in etherStatsTable. status: row status of the Ethernet statistics entry with the specified index, corresponding to the etherStatsStatus in etherStatsTable: undercreation(invalid), valid(valid), invalid(no valid statistics information). You can run the rmon statistics command to configure entry-number and owner.
Interface	Interface where statistics are collected, corresponding to the etherStatsDataSource object in etherStatsTable, followed by the interface OID.
Received	Number of received packets.
octets	Number of received octets.
packets	Number of received packets, corresponding to the etherStatsPkts object in etherStatsTable.
broadcast packets	Number of received broadcast packets, corresponding to the etherStatsBroadcastPkts object in etherStatsTable.
multicast packets	Number of received multicast packets, corresponding to the etherStatsMulticastPkts object in etherStatsTable.
undersize packets	Number of received undersize packets, corresponding to the etherStatsUndersizePkts object in etherStatsTable.
oversize packets	Number of received large packets, corresponding to the etherStatsOversizePkts object in etherStatsTable. NOTE: The S2720-EI, S5720I-SI, S5720-LI, S5735-L, S5735S-L, S5735S-L-M, S5720S-LI, S5720S-SI, S5720-SI, S5735-S, S5735S-S, S5735-S-I, S5730S-EI, S5730-SI, S6720-LI, S6720S-LI, S6720S-SI, and S6720-SI cannot collect statistics on the packets of which the lengths range from 1518 to n. n is the maximum frame length allowed by the interface, and can be set using the jumboframe enable command.
fragments packets	Number of received undersize and CRC error packets, corresponding to the etherStatsFragments object in etherStatsTable.
jabbers packets	Number of received large and CRC error packets, corresponding to the etherStatsJabbers object in etherStatsTable. NOTE: The S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S do not support this item.
CRC alignment errors	Number of received CRC error packets, corresponding to the etherStatsCRCAlignErrors object in etherStatsTable.
collisions	Number of received collision packets, corresponding to the etherStatsCollisions object in etherStatsTable.
Dropped packet	Number of discarded packets, corresponding to the etherStatsDropEvents object in etherStatsTable.
Packets received according to length	Number of received packets with different lengths, corresponding to the etherStatsPkts64Octets, etherStatsPkts65to127Octets, etherStatsPkts128to255Octets, etherStatsPkts256to511Octets, etherStatsPkts512to1023Octets, and etherStatsPkts1024to1518Octets objects in etherStatsTable.
